THE 10″ SUB WITH 12″ BASS

LISTEN TO THE SOUND OF LIMITS BEING SHATTERED

You should be wondering, “how can a 10 inch sub outperform a 12?” Well, let us explain.

Bass has to do with so much more than just woofer size. Sure woofer size is a factor, but so is cabinet volume, woofer excursion, and power. The fact is, bass is created by moving air. The more air you move, the more bass you get.

What the Speedwoofer 10S lacks in surface area, it more than makes up for with volume and excursion. This combination allows the Speedwoofer 10S to move more air and reach lower frequencies than top-rated 12″ competitors; but with the improved speed and transient response of a 10. Its the best of both worlds.

Of course, power plays a big role in overall performance as well. That’s why we gave the Speedwoofer 10S the most powerful amp in its class. Besides its monstrous 350 watts RMS, the Speedwoofer’s amp also has wireless technology built in. Add the optional wireless transmitter ($50) and make your Speedwoofer wireless up to 35ft.

The Speedwoofer’s performance defies logic. Nothing like it exists – unless you’re ready to double or triple your budget. But if you do that, why not just get two Speedwoofers and quadruple your bass output…

COMPRESSION GUIDE TECHNOLOGY

THE ACE UP OUR SLEEVE

STANDARD SPEAKERS & SUBS

Standard hollow cabinets do not address cabinet resonance. Resonance adds distortion which reduces sound quality. Speakers sound boxy and unnatural. Subwoofers are slower, prone to slop, and lack articulation.

RSL SPEAKERS & SPEEDWOOFERS

Compression Guide reduces cabinet resonance. Sound remains pure and unaltered. Speakers sound natural and life-like. Subwoofers become drastically faster and more articulate. Bass stays tight and clean at all frequencies.

Compression Guide technology is the difference between RSL Speedwoofers and all other subwoofers. It’s the secret behind our mind-blowing performance. It’s how our subwoofers provide so much power with flawless composure. Watch the video.

“By any measure, this is a fantastic 10-inch sub, one that in many ways delivers the performance of a 12-inch offering”

“It’s hard not to be impressed by the way the RSL sub doesn’t muddy the song’s rhythm section the way other (even much more expensive) subs do.”

This subwoofer is fantastic. Tight, fast, low, clean and down right awesome. The S.V.S. sub is $100 more and 50 watts R.M.S. less power. The Home Theater Direct one is $30 cheaper but 200 watts less R.M.S. in power. Why you would spend $800 - $1,500 on another company's sub when you could get 2 of these makes no sense. The Speedwoofer sounds great with CDs and DVDs. Buy it,. You will not be disappointed.

Holy Jumpin Junipers Batman! I ordered this for my 2 channel system in my bedroom. Primarily for music and streaming when I don't want to fire up the big system. Man Wow. I've never heard a 10 inch sub at this size with this much clean output. It disappears and blends perfect with the main speakers. It's fast musical accurate and tight and quiet in movies very nuance till BOOM!!! You need it to HIT for movies and I mean it hits HARD!!!! Any name brand Polk or Klipsch or Bic 12 incher it Destroys you have to pay WAY more at high-end companies to beat it. I like it so much I'm planning on stretching my budget and ordering another one for 2.2 in my bedroom. Well..... just because.

Good morning, my Speed Woofer arrived. I plug it in, LFE Bypass, set volume to 12 o’clock and WOW! You weren’t kidding tight, accurate and deep! I haven’t even rerun calibration on my Marantz SR-6012 Receiver and I am really, really impressed. This is the bass I have been looking for, exceptional product, very few pieces of audio bring about emotion. I’m sitting listening to Roger Waters Is This The Life You Really Want and with the addition of the Speedwoofer to my system I assure you, emotion is a feeling and the result. I have this album on HD FLAC 48KHz 24 bit and it is stunning with the Speedwoofer. Mind you I have a great music streamer DAC to complement, Cambridge Audio Azur 851N, but the sub made the difference tonight. Thank you for enhancing my musical and theatre experience.

Well I've been looking for a nice sounding subwoofer for sometime now. Read lots of reviews and found came across the speedwoofer 10s was a little skeptical about what this subwoofer was able to do. All I can say is WOW. I'm am truly impressed by the depth this 10" speaker can play. The accuracy of the speedwoofer 10s is simply amazing. I replaced my other home theather subwoofer which is a polk micropro 3000 which is 1200 watts rms and 2400 peak which cant play as deep as the speedwoofer 10s. I'm sold on RSL'S speedwoofer 10s and will be getting a second on for my theater room. Highly recommend speedwoofer 10s and if your unsure about the speedwoofer 10s don't be it's a winner.

For about 2 years time I only had one speedwoofer10s. Before I bought my first one I researched high and low for a decent subwoofer that could get pretty low while maintaining transients for music. I looked at REL subs but was flabbergasted by the price tag for their "budget" models. A good portion probably due to the easily scratchable piano finish. I came across the speedwoofer10s through audioholics' review and was impressed. The review gave me proper expectations for performance. I knew after I plugged and played music through my first one that I wanted another! I got really good impact from one but knee from my readings that two will eliminate the localisation of the subwoofer. So last week I pulled the trigger after saving some money on a second sub from their outlet. RSL found me the best shipping price (I live all the way up in Alaska) way better than what Monitor Audio quoted me for similar weighted bookshelf speakers shipping from the same area. I had some amplifier issues with the first subwoofer. Since the first run of the series they've improved the amps and were able to ship.me another one to replace it with. During my move to Alaska that amp broke as well and they sent me another amp then as well! Only had to pay shipping. I love so much that when I am out of the house I wish I could be home listening to them. If you're looking at a $800+ sub for mostly music don't waste your money. Just get two of these bad boys. I do have to say they don't dig as deep for movie LFE tracks as those other bigger, pricier subs. They will definitely pressurise your room down into gut feeling depths though and pack a big punch. Can't say enough that hasn't already been said about customer service. These are down to earth, great folks and I highly recomend them to all my friends.

I bought the speedwoofer 10s because of the great value and relatively small footprint. I was blown away by the quality and volume of bass that this sub produces. I loved it so much that I just purchased a second one to even out the dead spots in my home theater and create more Headroom. By far one of the best values and Subs you can buy. Strongly recommended!

Punchy, loud, fast... Speedwoofer 10S exactly as advertised. Bought it based on stellar customer and professional reviews. Heard demo subs in showrooms costing twice as much and I must say the Speedwoofer 10S can hang with the big boys. For the precision, price, free return shipping if needed and exceptional customer service, the Speedwoofer 10S is a NO BRAINER and a winner! Great job RSL!

Punchy, loud, fast... speedwoofer 10S is exactly what it is advertised for. I Bought one based on customer and professional reviews. I'm certainly not an audiophile but I've heard demos of other subs in showrooms that cost twice as much and I must say the Speedwoofer 10S can hang with them big boys! For the price, precision, free return shipping if needed, exceptional customer support (I spoke with Joe and he still managed to get it shipped the same day even I placed the order late in the afternoon), this thing is a NO BRAINER!

Wow! I told you that I would get back to you on the dual 10'S subs. I am punishing them right now with some NIN. And they sound fantastic! Clean accurate and they are hitting me in the chest. And I don't have the volume up much at all, well below the 12oclock position.

I purchased two RSL speed woofers and I couldn't be happier with my purchase. First, in regards to customer service, there was a bit of an issue with shipping when I ordered of largely my own making. RSL were very quick to respond once it was identified, and went well beyond what I expected to address the issue. They even took the time to ask me about my setup and discuss some of the different options. You can rest assured you'll be looked after in ordering direct online. In terms of sound quality, like a lot of folks, I wondered if a sub this small was going to be able to produce great sounding deep bass, especially given the price point and features. Figured they had to cut corners somewhere, right? But with all the rave reviews from the professional reviewers and the big audiophile forums, I ordered two. Two months later with 50/50 split source material, I couldn't be happier with the sound stage, overall responsiveness, and build quality. No chuffing or distortion, just very punchy and tight room filling bass. I listened to a lot of subs that sell for over 2x the 10s price before purchasing, and they were not materially better and/or don't have the features of the 10s. The wireless receiver is an outstanding add. RSL have a set a new benchmark for up to medium sized listening environments. I would struggle to recommend anything else.

OH.MY.GOODNESS. I had very high expectations after reading the professional and consumer reviews and the long anticipation of the last many months while I waited to actually pull the trigger. I was going to get two, but dear lord what on earth would I do with 4x the output? I have a rather large listening room, 20x20 and 16ft cathedral ceilings. I'm running a simple stereo setup: Denon PMA-50 integrated bluetooth amp, powering my delicious Paradigm Reference Studio Monitor 20's. The set up is so good, all by itself I've hesitated to put a sub with it. I'm absolutely floored by the impact the RSLSpeedwoofer10s has. Its shocking for its size. The speed of its response feels instant, no hangover or mud even at incredible pressure levels. Keith Urban 'Ripcord' about collapsed my chest - felt like the kick drum thumper thing was actually hitting my chest. Tight, tight, tight beat after beat after beat. Sam Hunt 'Come Over' acoustic version produced a sound stage so large and multidimensional I felt pulled into the false reality that I was in fact at a live performance. Utterly startling, phenomenally great! A few Shakira beats and a Despacito at volume levels that are completely unreasonable and the RSL is unflappable. I may have to take a vacation day tomorrow to enjoy it because the few hours after work that I can play it loud are too few. Set up was pretty quick, when its in the 'right' spot it just melds with its surrounding. Internal crossover is perfect. I almost feel bad only having paid $399. Thank you RSL for letting me have it, you can't have it back 🙂 so you can put your 30 day free return in the drawer...

We, meaning the wife and I, she love's subwoofers, were sooooooooooooooooooo glad we waited for the subs to watch Justice League I am so impressed with these little monsters. As a matter of fact, I must have said that to my wife like 10 times during the movie. I know I'm missing some of the subsonic frequencies, but, what these subs do, they do with an outstanding mixture of finesse and vengeance. I couldn't be more happy with this or any purchase. I hate this upcoming phrase because it always seems to let the air out of a review but sometimes it has to be said. ( for what you pay here ) you are getting 2 or 3 times that price performance. I've had Velodyne, Sunfire, Reaction Audio, B&W, SVS and many more I that can't even remember and the only one that was as accurate as my speedwoofers was the B&W ASW10, very musical but even it couldn't hit as hard as the speedwoofers. Now the SVS PB2PLus was a monster indeed and could shake your butt at 16Hz but I'll gladly give up that for the frigging power punch the speedwoofers have all the way to their lowest frequency, which in my room is about 22Hz. I can't wait to pair them with my soon to be here CG3's and CG23's. Were gonna break some sh** lol - Thank you Joe and than you RSL for taking the time to create such an overachieving product and for allowing the public to enjoy your creations without sending us all to the poor house. 10's across the board......

After about a month with this sub plugged into my system, I just wanted to say how thoroughly impressed I am with the overall performance of the Speedwoofer 10S. This sub replaced an older version of the Velodyne SPL-1000, which cost more than 2 times as much and was rated at 750watts RMS power. I was always happy with the Velodyne, but now, in comparison, the 10S can easily provide as much room-shaking bass for movie watching, but with less distortion. When it comes to music, for me, this is where the 10S really shines. I'm blown away by how fast and tight the bass is-it just makes my entire system sound so much better! I find myself listening to old CDs that I hadn't played in years. Only negative, which has nothing to do with the 10S itself, is that for Canadians, after exchange, taxes etc, the cost is closer to $700,but even with that, no regrets on purchasing the Speedwoofer 10S.

I've replaced my two 12'' Klipsch subs with two RSL Speedwoofer 10S and I'm very impressed. These 10'' guys sound much better than my dual Klipsch. Klipsch were not bad for the money and delivered tight and precise bass, however Speedwoofer is a killer sub at $399. I can't recommend it enough. Even my wife noticed the difference and was impressed. Just buy two of them and stop searching for the best bass under $1k.

If you're reading this review then I'll do you a favor by starting off with the conclusion; this subwoofer is fantastic. I demo'ed a couple different subwoofers (including an extended in-home demo of a popular factory direct company) and dollar for dollar this sub was the best. I have a dedicated home theater that is 12x14x8, which is filled with powerful bass at about 1/3 volume on the sub. In comparison, the in-home demo was the sealed box version of a 12" woofer that was good, but not great considering the specs touted on their website. The RSL is, without a doubt, one of the best values I've come across in regards to home theater.

As you know, the only thing older than my system is me; but only by a few years. I was initially pleased with how the 10S rounded out the bottom end of my music - very fast and quite accurate. The surprise came when pushing the system (hard). The main speaker in the room is the pair of EV SP15's, their combined Alnico magnet weight of around 50 pounds, the Altec 511B with 802HD horn and the EV SP350 tweeter - all stuffed into a 36cf cabinet with an approx efficiency of well over 100db / 1 watt/ 1 meter. Also a pair of Klipsch KG 4.2's (about 95db /1 /1) to fill the balance of my 12'x16' room. Cranking up to MPL (Medium Pain Level) with Shaggy's "It Wasn't Me" (Tropical House remix) immediately dispelled any thoughts of the 10S not keeping up with the efficiency of the rest of the speakers; for with the 10S volume set at the 11:00 position, I soon found my corpulent torso vibrating across the room in syncopation with the music - albeit in an finely articulated and well-defined manner. Did further experiments with Matchbox 20's "Damn," Enya's "Broadicea" and Buena Vista Social Club & Coldplay's "Clocks" and your 10S did all it was supposed to do without a stumble. Even when moving up to the AVL (Aural Vasectomy Level) the 10S maintained composure, though it's volume had to be turned up. Thank you for delivering on all levels; the 10S's quality, accuracy and musicality are indeed music to the ears and an amazing value as well.

I watched The Dark Tower and it was like I had never even turned the subs on before it was that noticeable.

First, I am a seasoned audioholic. I looked at several brands, but the size and aesthetic of this sub spoke to me, and the customer service before even buying was excellent, so I was very comfortable. Numerous stellar reviews from the major AV mags/web sites sealed the deal. I could go on and on about how much I love this subwoofer, it was love at first sight really. And then I plugged it in. The test tone from my Onkyo told me I was dealing with an entirely different breed. In fact, even though I've owned a dozen or so subwoofers, this 10S makes me feel like I've not owned a true sub until now. Suffice it to say, after listening to some great tracks with ample low end, this thing is seriously amazing. Tight, controlled, musical bass. Yes I'm starting off with a different brand of mains I've had for a while, but I was able to blend the sub right in with my system. After some tunes, I put on Dead Pool Blu Ray, running through an Onkyo RZ710. Even with the bass dialed back minus 2 db on the receiver, with sub set at about 11 o'clock, the 10S filled the room with authority-this thing is like a tank on air ride suspension. I will eventually get another and go dual sub, which at this price point is a great proposition over one 800.00 dollar sub. And the fact that wireless is inside, at 399.00---insane. I didn't know quite what I was missing until this baby arrived cloaked in cardboard and foam, but I would not wanna be without her. The Speedwoofer 10S has piqued my interest in seeing what RSL's speaker line is like, I will definitely be considering some stereo mains. I'd say the folks at RSL have done a stellar job with the Speedwoofer, I'm more excited than ever to listen to music and movies. Thank you RSL!

Was everything the reviews say. Can't go wrong with these, unless you have extreme tastes, and if you do you probably wouldn't mind spending MUCH more to find something better anyway. I had some reservations about it filing my large open ended theater area, and they do just fine. Bass is tight and precise and there is enough rumble not even turning it up past 50%. Getting two for $800 is probably the best bang for your buck i can think of and despite being a great value that isn't to say these are "cheap" in any way. Great product, and always a pleasure to do business with RSL, awesome customer service. Got these to my door (in Hawaii) in no time and communication was prompt, personable, and knowledgeable as usual.

Hello. I want to share my impression of the subwoofer. In music, the subwoofer gives accurate solid bass.Even on the fastest songs in the style of rock very good intelligibility bass. The subwoofer does not create distortion, headroom is very large. That is very important to me that in the movies it sounds great. The feeling that you have managed to combine the best qualities of the subwoofer with a closed box and bass reflex. Compared to my previous VELODYNE subwoofer it plays much better, much deeper. You created a versatile subwoofer that plays both in music and in film. System auto off works very well. I'm glad I listened to your advice and bought the subwoofer. I wish you success in your business, and hope that many will appreciate your products.

Bought this after a Velodyne VX-11 plate amp went bad on a sub only 3-1/2 years old. Anyway, sound to me is very similar to my Velodyne but it goes down about another 10 HZ. Takes up a bit more floor space too, but I'm very happy with the quality. Have tested out full orchestra and organ pieces with low bass notes as well as extremely low end frequency effects in THX and movie sound track demos and the output was excellent and clean at fairly loud levels.. enough to feel the bass through the seat of my pants through the couch and floor!

Best sub I've ever owned. I have a decent sized room (20x20 with cathedral ceilings). I have this sub matched with a Marantz SR5010 receiver, Dynaudio Emit M20 fronts, Emit M15c center, and Martin Logan Motion4 surrounds. This setup has PLENTY of power for that room. The sub is great for the 5.1 home theater, but it really shines when playing music. It blends so well with the rest of the system. Not boomy, not muddy, just sweet, solid bass. I debated between this and the SVS SB-1000. Glad I went with the Speedwoofer! Fast shipping and great customer service.

Received this 2 weeks ago, and using it on a Onkyo & Klipsch 7.1 system. Wow what a difference from the Klipsch subs (muddy, chuffing, ground loops hums on both the 10" and 12" Klipsch tried separately) . I didnt want to keep blowing a lot of money on subs but I really need clear quality sound, so the AVS forum steered me here. They werent kidding when they said this thing packs a punch. There wasnt even one negative comment about this product, seemed universally liked. Customer service was praised too. So I pulled the trigger and couldnt be happier. Wish I would have saved myself the headaches and got this first. Pros: + Tight, concise, loud. + The bass is fast and doesnt overshadow the rest of the system. + No ground loop hum, I had hum with both Klipsch I tried. + Wifi adapter was simple to set up, I probably didnt need to read the directions for that. + Best bang per buck, you cant find quality like this without spending twice as much. + Customer service answered on 2 rings and they seemed to already have my info up, they simply asked my first name and told me the order status and explained a few finer points of their subwoofer and wanted me to call them if I had any questions at all. Good people! Cons: None, except I see they're temporarily out of stock now and I wanted to buy another.

I did initially have some setup issues with the sub and called the support number. Howard gave me several troubleshooting tips that ultimately resulted in a great sounding system. The sub is great, but even better is the tremendously responsive, knowledgeable, and helpful customer service provided by RSL. Thanks Howard! Perhaps Howard could talk to my wife about getting a sub for the other room...

Overly impressed with the output of the Speedwoofer 10s in my 5000ft³ living room. I was skeptical of the performance of a 10" driver but after having it for about a week I am convinced. Looking forward to getting a second!

I have been wanting some subwoofers for my home theater setup for a few years. I had it down to RSL, SVS, Hsu amd DIY. I read and read and read and finally thought I would go with the companies that offered free shipping. I just revieved my RSL Speedwoofer 10S today and got them set up. I dont think I will be auditioning anymore subs, I have found the ONE. These things are AWESOME. I put in San Andreas and listened to the earthquake sequence and was blown away. This was at a volume level of 1/3. They will only get better with the break in period. My wife told me everyone will have to buy earplugs now, what a compliment. I also want to say a big THANK YOU to Howard for his help when I called, so easy to talk to and very up front. If you are in the market for some awesome subs get the Speedwoofer you will not be disappointed. I forgot to say I have a BIG room and it is filled with base. I cannot wait for my daughters to hear this now.

Well I received my Speedwoofer yesterday. I set it up in a front right position next to my aj pioneer tower. I performed the denon 910w audessy set up and made some minor tweaks of my own. My wife then joined me to watch Captain America civil war. All I can say is WOW! Now mind you my previous sub was an htib sony pos. so im probably not the best person to trust for a glowing reccomendation. This subs bass was tight and explosive. The wife stated we wouldnt need to schedule any massage appointments, just go to the theater room and crank up an action movie! I took that as a positive reinforcement that this sub was a great investment. The pioneer AJ speakers now sound like a millon bucks as compared to before.

I've had my new Speedwoofer 10S for 2 weeks now and I LOVE it! I have a very challenging medium sized room that opens up to one side into the kitchen. (The dreaded "L" shaped room). The back of the room opens up again into a hallway. I've learned a lot about acoustics recently and an L shaped room is about as bad as it gets. Additionally, there's only one spot I can put a single sub, both for sound and aesthetics.(wifey influence:)) Long story short- THIS SUB IS AWESOME! It fills my jacked up room with Deep wonderfully accurate BASS. Seriously, do your research. The 10S competes with subs that cost twice as much. I would tell anyone considering another company's single $800 sub to just get two Speedwoofers.. You can't beat a multi sub setup and all of its advantages for ONLY $798 shipped!! Trust me, as soon as I can convince the wife I'll be getting another one:). I am by no means saying that one of these subs won't be enough though. It really is an amazing product at an amazing price. Check out the Audioholics review of this sub. If you're not familiar with the guys at Audioholics, get familiar:) If you care about sound:) They test $2000 subs all day long and they are blown away by the 10S's performance at this price point. Anyways, I could go on but put simply- I LOVE IT! I have to add that RSL's customer service is really outstanding! When you call them there's this crazy thing that happens-- A HUMAN PICKS UP "and" they know what they're talking about!!! I had some specific questions that were answered promptly by email as well. I got very friendly and helpful well thought out assistance - EVERY TIME:) Mr. Rogers himself was the man I was corresponding with. Seriously awesome customer service. This will not be my last purchase from RSL. I plan on replacing my front LCR's with 3 of their monitors and getting that second sub to complete my 7."2" system the right way.👍🏼👍🏼 J. Wright

I have to say you can not beat the service we have received from RSL...sound advice, prompt shipping (2.5 days to Canada) and a fabulous product. After a long trial there is no doubt that the sound quality of the 10S has been far superior to our old Paradigm sub, especially when it comes to music.

As a legally blind audio enthusiast sound is very important to me. I have pretty good speakers (Polk LSI/M) for my home theater setup. However, I never really thought of a sub as anything more than a big noise box that goes into action for movie explosions so I didn't put much of a priority on that piece of the HT puzzle. After reading a review in Sound and Vision I decided to upgrade from a Polk PSW 505 to the Speedwofer 10s. I had been happy enough with the Polk for a couple of years as it was more than loud enough for my listening area (roughly 3,000 cubic feet). I was a little concerned at going down from a 12" to a 10" driver, but my fears quickly subsided. The Speedwoofer 10s is surprisingly powerful. Using the audio setup on my Marantz receiver the 10s needed to be turned down a bit even with the volume knob of the sub set to the middle of it's range. So, plenty more power than my room needs. With the "is it enough" question answered I started playing through movie scenes and music that I am familiar with. The thing that struck me the most was how musical the sub sounds. I never thought of a sub in terms of music, but I didn't know what I was missing. Listening to the album Mama's Gun by Erykah Badu I heard subtle tones in the baselines that I didn't know existed. And hearing detail in the rumbles and shakes of movies was equally shocking. Who knew? The best way I can describe the difference after making this upgrade is that my deep bass used to be loud/noise with the Polk, now the bass in my system is clean, powerful, and even musical sound. And the icing on the cake: My wife took one look at it and said that she was happy I made the switch because the 10s "looks" much nicer. This is something that obviously never occurred to me, but it's definitely an added bonus when HT equipment is met with wife approval. I couldn't be happier with this sub. Thanks RSL.

Hello RSL: I have had the 10s sub for more than a month now. I previously was using a 1993 (!!!) Velodyne VA1012 B, but it developed a hum issue. I read the review in S & V, saw the incredible try-before-you-buy deal, and gave it a shot. The bass notes I am just now discovering in much of my music has been eye (ear?)-opening to say the least. The Velodyne did well with slow, deep bass but missed an incredible amount of transients in "quicker" notes. I now sit in my listening room and just pick random tracks from my streaming collection, enjoying the discovery of all the new bass information. As a bonus, with the crossover control I can get a nearly seamless transition from my Goldenears 3D Array soundbar and Invisa in-walls to the 10s. The Velodyne was set at 75 hz, which taxed the soundbar's abilities. Now the soundbar is free to focus on the frequency range it excels at, which has revealed a whole new level of music information coming through the speakers. All in all, the 10s has transformed my system in the most substantial manner I have ever heard. And the price??? Incredible!!! (The Velodyne set me back $699 in 1993)! WELL DONE!

Honestly this sub packs a punch! I was anxiously waiting for it and it finally arrived home last week Fri 8/26. When i connected this bad boy to my Onkyo receiver with another previous RSL sub i have, it blew me AWAY i felt the base running through the floor into my couch all the way to my chest!!! Woooo Hoooo!!! pure raw organic base with no muddiness. Im impressed with the sound, the quality, and the power this sub has. To finish my review i have to thank the guys in RSL for the phenomenal work, customer service and attention to detail they have.

My subwoofer 10S arrived on June 24 and got quickly put into service.WOW! It is impressive - it keeps up with my Magnapan MG12s nicely. I rattled my window A/C right off so down went the volume. I have lots of organ CD's which notably sound much better, but feel like real organs. As for movies, I think all subwoofer manufactures have a deal with moviemakers to show off explosions,and ominous low stuff, etc. to help sell the movies on DVDs - even Neflix. I just wish I had the space & $ to get surround sound, but your woofer puts me in the ballpark. Hope you do well and thanks much for your help on the phone.

Wanted to let you know some preliminary experience w/ my Speedwoofer 10S. Had chance yesterday evening to put on some music which I think took advantage of the Speedwoofer. Music overall sounded fuller, and richer, than I think it did before. I temper my comments with guidance that I'm not an audiophile or audio expert, but, thus far, the 10Ss is a welcome addition in my system. Looking forward to further listening, breaking in the speaker. And, eventually, adding the RSL in-wall and ceiling speakers to replace those which I inherited with my house.

First off let me say I highly recommend the speedwoofer 10s I have two and they are fast and accurate. A good match if you own magneplaner speakers, a tough feat for any sub. Read the professional reviews the only thing I'd add is I definitely don't feel I need any more low end or extension. The reason I'm writing this review is because of the amazing passion Howard has for his speakers and his company. I ordered my Sub's on Friday and July 4th was Monday so good chance I was going to have to wait for my new shiny toy. So then I get the following email from the owner of the company:

Hi Kevin,
Thank you again for your order. The warehouse was backed up today and told us it would be difficult to fill your order today. Since Monday is a holiday and they won't be working, I insisted that they ship at least one of the Speedwoofers and the wireless transmitter so you could get it as soon as possible. They did that and the tracking number is: Xxxxxxxxxxx
To track the order, please visit http://www.fedex.com/us/. A signature is required upon delivery for all orders over $500. The second Speedwoofer 10S will be shipped on Tuesday and we can get you the tracking number for that Tuesday night.
If you have any questions, don't hesitate to ask us. We're always happy to provide expert support.
Have a great weekend and 4th!
Best regards,
Howard

Ok now this is a man who knows how exciting it is to receive a new purchase and how hard it is to wait. This is a company run by a true passion for there speakers! You WILL be treated exceptionally well.

I have received the sub-woofer last week, I have installed it on Saturday. So now the so call “braking time” is over. And my reaction is … WOW !!!

So I am very happy with my purchase.

I want to congratulate you guys on a job well done. I ordered both your 10s and the svs sb1000. I already have the sb13 in my designated home theater but I wanted a cheaper sub for the living room. Since both you and svs offer the home trial (actuallt svs trial is slightly longer) I could just return the sub I liked the least. I have to say I love my sb13 and expected wind up with the sb1000 as well, but figured I'd give the 10s a shot. Well somewhat to my surprise, I sent back the sb. Its a very good sub but doesn't seem to handle the lows quite as well. I was also pleasantly surprised at how much I could feel the bass from the 10s. It was more than I was expecting from something so inexpensive, about 100 dollars less than the sb. You've got a good little sub here. Great service to boot.

This subwoofer is fantastic. Tight, fast, low, clean and down right awesome. The S.V.S. sub is $100 more and 50 watts R.M.S. less power. The Home Theater Direct one is $30 cheaper but 200 watts less R.M.S. in power. Why you would spend $800 - $1,500 on another company's sub when you could get 2 of these makes no sense. The Speedwoofer sounds great with CDs and DVDs. Buy it,. You will not be disappointed.

Holy Jumpin Junipers Batman! I ordered this for my 2 channel system in my bedroom. Primarily for music and streaming when I don't want to fire up the big system. Man Wow. I've never heard a 10 inch sub at this size with this much clean output. It disappears and blends perfect with the main speakers. It's fast musical accurate and tight and quiet in movies very nuance till BOOM!!! You need it to HIT for movies and I mean it hits HARD!!!! Any name brand Polk or Klipsch or Bic 12 incher it Destroys you have to pay WAY more at high-end companies to beat it. I like it so much I'm planning on stretching my budget and ordering another one for 2.2 in my bedroom. Well..... just because.

Good morning, my Speed Woofer arrived. I plug it in, LFE Bypass, set volume to 12 o’clock and WOW! You weren’t kidding tight, accurate and deep! I haven’t even rerun calibration on my Marantz SR-6012 Receiver and I am really, really impressed. This is the bass I have been looking for, exceptional product, very few pieces of audio bring about emotion. I’m sitting listening to Roger Waters Is This The Life You Really Want and with the addition of the Speedwoofer to my system I assure you, emotion is a feeling and the result. I have this album on HD FLAC 48KHz 24 bit and it is stunning with the Speedwoofer. Mind you I have a great music streamer DAC to complement, Cambridge Audio Azur 851N, but the sub made the difference tonight. Thank you for enhancing my musical and theatre experience.

Well I've been looking for a nice sounding subwoofer for sometime now. Read lots of reviews and found came across the speedwoofer 10s was a little skeptical about what this subwoofer was able to do. All I can say is WOW. I'm am truly impressed by the depth this 10" speaker can play. The accuracy of the speedwoofer 10s is simply amazing. I replaced my other home theather subwoofer which is a polk micropro 3000 which is 1200 watts rms and 2400 peak which cant play as deep as the speedwoofer 10s. I'm sold on RSL'S speedwoofer 10s and will be getting a second on for my theater room. Highly recommend speedwoofer 10s and if your unsure about the speedwoofer 10s don't be it's a winner.

For about 2 years time I only had one speedwoofer10s. Before I bought my first one I researched high and low for a decent subwoofer that could get pretty low while maintaining transients for music. I looked at REL subs but was flabbergasted by the price tag for their "budget" models. A good portion probably due to the easily scratchable piano finish. I came across the speedwoofer10s through audioholics' review and was impressed. The review gave me proper expectations for performance. I knew after I plugged and played music through my first one that I wanted another! I got really good impact from one but knee from my readings that two will eliminate the localisation of the subwoofer. So last week I pulled the trigger after saving some money on a second sub from their outlet. RSL found me the best shipping price (I live all the way up in Alaska) way better than what Monitor Audio quoted me for similar weighted bookshelf speakers shipping from the same area. I had some amplifier issues with the first subwoofer. Since the first run of the series they've improved the amps and were able to ship.me another one to replace it with. During my move to Alaska that amp broke as well and they sent me another amp then as well! Only had to pay shipping. I love so much that when I am out of the house I wish I could be home listening to them. If you're looking at a $800+ sub for mostly music don't waste your money. Just get two of these bad boys. I do have to say they don't dig as deep for movie LFE tracks as those other bigger, pricier subs. They will definitely pressurise your room down into gut feeling depths though and pack a big punch. Can't say enough that hasn't already been said about customer service. These are down to earth, great folks and I highly recomend them to all my friends.

I bought the speedwoofer 10s because of the great value and relatively small footprint. I was blown away by the quality and volume of bass that this sub produces.

Strongly recommended!

I purchased two RSL speed woofers and I couldn't be happier with my purchase. First, in regards to customer service, there was a bit of an issue with shipping when I ordered of largely my own making. RSL were very quick to respond once it was identified, and went well beyond what I expected to address the issue. They even took the time to ask me about my setup and discuss some of the different options. You can rest assured you'll be looked after in ordering direct online. In terms of sound quality, like a lot of folks, I wondered if a sub this small was going to be able to produce great sounding deep bass, especially given the price point and features. Figured they had to cut corners somewhere, right? But with all the rave reviews from the professional reviewers and the big audiophile forums, I ordered two. Two months later with 50/50 split source material, I couldn't be happier with the sound stage, overall responsiveness, and build quality. No chuffing or distortion, just very punchy and tight room filling bass. I listened to a lot of subs that sell for over 2x the 10s price before purchasing, and they were not materially better and/or don't have the features of the 10s. The wireless receiver is an outstanding add. RSL have a set a new benchmark for up to medium sized listening environments. I would struggle to recommend anything else.

OH.MY.GOODNESS. I had very high expectations after reading the professional and consumer reviews and the long anticipation of the last many months while I waited to actually pull the trigger. I was going to get two, but dear lord what on earth would I do with 4x the output? I have a rather large listening room, 20x20 and 16ft cathedral ceilings. I'm running a simple stereo setup: Denon PMA-50 integrated bluetooth amp, powering my delicious Paradigm Reference Studio Monitor 20's. The set up is so good, all by itself I've hesitated to put a sub with it. I'm absolutely floored by the impact the RSLSpeedwoofer10s has. Its shocking for its size. The speed of its response feels instant, no hangover or mud even at incredible pressure levels. Keith Urban 'Ripcord' about collapsed my chest - felt like the kick drum thumper thing was actually hitting my chest. Tight, tight, tight beat after beat after beat. Sam Hunt 'Come Over' acoustic version produced a sound stage so large and multidimensional I felt pulled into the false reality that I was in fact at a live performance. Utterly startling, phenomenally great! A few Shakira beats and a Despacito at volume levels that are completely unreasonable and the RSL is unflappable. I may have to take a vacation day tomorrow to enjoy it because the few hours after work that I can play it loud are too few. Set up was pretty quick, when its in the 'right' spot it just melds with its surrounding. Internal crossover is perfect. I almost feel bad only having paid $399. Thank you RSL for letting me have it, you can't have it back 🙂 so you can put your 30 day free return in the drawer...

We, meaning the wife and I, she love's subwoofers, were sooooooooooooooooooo glad we waited for the subs to watch Justice League I am so impressed with these little monsters. As a matter of fact, I must have said that to my wife like 10 times during the movie. I know I'm missing some of the subsonic frequencies, but, what these subs do, they do with an outstanding mixture of finesse and vengeance. I couldn't be more happy with this or any purchase. I hate this upcoming phrase because it always seems to let the air out of a review but sometimes it has to be said. ( for what you pay here ) you are getting 2 or 3 times that price performance. I've had Velodyne, Sunfire, Reaction Audio, B&W, SVS and many more I that can't even remember and the only one that was as accurate as my speedwoofers was the B&W ASW10, very musical but even it couldn't hit as hard as the speedwoofers. Now the SVS PB2PLus was a monster indeed and could shake your butt at 16Hz but I'll gladly give up that for the frigging power punch the speedwoofers have all the way to their lowest frequency, which in my room is about 22Hz. I can't wait to pair them with my soon to be here CG3's and CG23's. Were gonna break some sh** lol - Thank you Joe and than you RSL for taking the time to create such an overachieving product and for allowing the public to enjoy your creations without sending us all to the poor house. 10's across the board......

After about a month with this sub plugged into my system, I just wanted to say how thoroughly impressed I am with the overall performance of the Speedwoofer 10S. This sub replaced an older version of the Velodyne SPL-1000, which cost more than 2 times as much and was rated at 750watts RMS power. I was always happy with the Velodyne, but now, in comparison, the 10S can easily provide as much room-shaking bass for movie watching, but with less distortion. When it comes to music, for me, this is where the 10S really shines. I'm blown away by how fast and tight the bass is-it just makes my entire system sound so much better! I find myself listening to old CDs that I hadn't played in years. Only negative, which has nothing to do with the 10S itself, is that for Canadians, after exchange, taxes etc, the cost is closer to $700,but even with that, no regrets on purchasing the Speedwoofer 10S.

I've replaced my two 12'' Klipsch subs with two RSL Speedwoofer 10S and I'm very impressed. These 10'' guys sound much better than my dual Klipsch. Klipsch were not bad for the money and delivered tight and precise bass, however Speedwoofer is a killer sub at $399. I can't recommend it enough. Even my wife noticed the difference and was impressed. Just buy two of them and stop searching for the best bass under $1k.

If you're reading this review then I'll do you a favor by starting off with the conclusion; this subwoofer is fantastic. I demo'ed a couple different subwoofers (including an extended in-home demo of a popular factory direct company) and dollar for dollar this sub was the best. I have a dedicated home theater that is 12x14x8, which is filled with powerful bass at about 1/3 volume on the sub. In comparison, the in-home demo was the sealed box version of a 12" woofer that was good, but not great considering the specs touted on their website. The RSL is, without a doubt, one of the best values I've come across in regards to home theater.

As you know, the only thing older than my system is me; but only by a few years. I was initially pleased with how the 10S rounded out the bottom end of my music - very fast and quite accurate. The surprise came when pushing the system (hard). The main speaker in the room is the pair of EV SP15's, their combined Alnico magnet weight of around 50 pounds, the Altec 511B with 802HD horn and the EV SP350 tweeter - all stuffed into a 36cf cabinet with an approx efficiency of well over 100db / 1 watt/ 1 meter. Also a pair of Klipsch KG 4.2's (about 95db /1 /1) to fill the balance of my 12'x16' room. Cranking up to MPL (Medium Pain Level) with Shaggy's "It Wasn't Me" (Tropical House remix) immediately dispelled any thoughts of the 10S not keeping up with the efficiency of the rest of the speakers; for with the 10S volume set at the 11:00 position, I soon found my corpulent torso vibrating across the room in syncopation with the music - albeit in an finely articulated and well-defined manner. Did further experiments with Matchbox 20's "Damn," Enya's "Broadicea" and Buena Vista Social Club & Coldplay's "Clocks" and your 10S did all it was supposed to do without a stumble. Even when moving up to the AVL (Aural Vasectomy Level) the 10S maintained composure, though it's volume had to be turned up. Thank you for delivering on all levels; the 10S's quality, accuracy and musicality are indeed music to the ears and an amazing value as well.

First, I am a seasoned audioholic. I looked at several brands, but the size and aesthetic of this sub spoke to me, and the customer service before even buying was excellent, so I was very comfortable. Numerous stellar reviews from the major AV mags/web sites sealed the deal. I could go on and on about how much I love this subwoofer, it was love at first sight really. And then I plugged it in. The test tone from my Onkyo told me I was dealing with an entirely different breed. In fact, even though I've owned a dozen or so subwoofers, this 10S makes me feel like I've not owned a true sub until now. Suffice it to say, after listening to some great tracks with ample low end, this thing is seriously amazing. Tight, controlled, musical bass. Yes I'm starting off with a different brand of mains I've had for a while, but I was able to blend the sub right in with my system. After some tunes, I put on Dead Pool Blu Ray, running through an Onkyo RZ710. Even with the bass dialed back minus 2 db on the receiver, with sub set at about 11 o'clock, the 10S filled the room with authority-this thing is like a tank on air ride suspension. I will eventually get another and go dual sub, which at this price point is a great proposition over one 800.00 dollar sub. And the fact that wireless is inside, at 399.00---insane. I didn't know quite what I was missing until this baby arrived cloaked in cardboard and foam, but I would not wanna be without her. The Speedwoofer 10S has piqued my interest in seeing what RSL's speaker line is like, I will definitely be considering some stereo mains. I'd say the folks at RSL have done a stellar job with the Speedwoofer, I'm more excited than ever to listen to music and movies. Thank you RSL!

Was everything the reviews say. Can't go wrong with these, unless you have extreme tastes, and if you do you probably wouldn't mind spending MUCH more to find something better anyway. I had some reservations about it filing my large open ended theater area, and they do just fine. Bass is tight and precise and there is enough rumble not even turning it up past 50%. Getting two for $800 is probably the best bang for your buck i can think of and despite being a great value that isn't to say these are "cheap" in any way. Great product, and always a pleasure to do business with RSL, awesome customer service. Got these to my door (in Hawaii) in no time and communication was prompt, personable, and knowledgeable as usual.

Holy s___t this subwoofer is a beast ! It's so powerful. I have a huge 30 x 20 family room and this thing is filling my entire room with accurate bass from the Tron movie. And by the way my last sub was a pb ultra 13 svs. This rsl produces much tighter bass. I knew it was high quality by the components

Hello. I want to share my impression of the subwoofer. In music, the subwoofer gives accurate solid bass.Even on the fastest songs in the style of rock very good intelligibility bass. The subwoofer does not create distortion, headroom is very large. That is very important to me that in the movies it sounds great. The feeling that you have managed to combine the best qualities of the subwoofer with a closed box and bass reflex. Compared to my previous VELODYNE subwoofer it plays much better, much deeper. You created a versatile subwoofer that plays both in music and in film. System auto off works very well. I'm glad I listened to your advice and bought the subwoofer. I wish you success in your business, and hope that many will appreciate your products.

Bought this after a Velodyne VX-11 plate amp went bad on a sub only 3-1/2 years old. Anyway, sound to me is very similar to my Velodyne but it goes down about another 10 HZ. Takes up a bit more floor space too, but I'm very happy with the quality. Have tested out full orchestra and organ pieces with low bass notes as well as extremely low end frequency effects in THX and movie sound track demos and the output was excellent and clean at fairly loud levels.. enough to feel the bass through the seat of my pants through the couch and floor!

I ended up getting one sub and placed it behind on the back wall. What an incredible product. I can't imagine what two would be like because one shakes the room. It just blows me away how good it is. I've heard $3500 subs that I swear don't have the sound this does. What a product to be proud of!

Best sub I've ever owned. I have a decent sized room (20x20 with cathedral ceilings). I have this sub matched with a Marantz SR5010 receiver, Dynaudio Emit M20 fronts, Emit M15c center, and Martin Logan Motion4 surrounds. This setup has PLENTY of power for that room. The sub is great for the 5.1 home theater, but it really shines when playing music. It blends so well with the rest of the system. Not boomy, not muddy, just sweet, solid bass. I debated between this and the SVS SB-1000. Glad I went with the Speedwoofer! Fast shipping and great customer service.

Received this 2 weeks ago, and using it on a Onkyo & Klipsch 7.1 system. Wow what a difference from the Klipsch subs (muddy, chuffing, ground loops hums on both the 10" and 12" Klipsch tried separately) . I didnt want to keep blowing a lot of money on subs but I really need clear quality sound, so the AVS forum steered me here. They werent kidding when they said this thing packs a punch. There wasnt even one negative comment about this product, seemed universally liked. Customer service was praised too. So I pulled the trigger and couldnt be happier. Wish I would have saved myself the headaches and got this first. Pros: + Tight, concise, loud. + The bass is fast and doesnt overshadow the rest of the system. + No ground loop hum, I had hum with both Klipsch I tried. + Wifi adapter was simple to set up, I probably didnt need to read the directions for that. + Best bang per buck, you cant find quality like this without spending twice as much. + Customer service answered on 2 rings and they seemed to already have my info up, they simply asked my first name and told me the order status and explained a few finer points of their subwoofer and wanted me to call them if I had any questions at all. Good people! Cons: None, except I see they're temporarily out of stock now and I wanted to buy another.

I recently added a second speed woofer 10 for a total of nine RSL speakers in my system. My goal was to create a wall of perfectly wonderful sound! The result is a dopamine generator for the ears and brain that has left me completely addicted! Thank you Howard and son for this problem!

I've had the Speedwoofer 10s for about 2 months and am very happy with it. The sound is fantastic with deep, clean, and responsive bass. I did initially have some setup issues with the sub and called the support number. Howard gave me several troubleshooting tips that ultimately resulted in a great sounding system. The sub is great, but even better is the tremendously responsive, knowledgeable, and helpful customer service provided by RSL. Thanks Howard! Perhaps Howard could talk to my wife about getting a sub for the other room...

I have been wanting some subwoofers for my home theater setup for a few years. I had it down to RSL, SVS, Hsu amd DIY. I read and read and read and finally thought I would go with the companies that offered free shipping. I just revieved my RSL Speedwoofer 10S today and got them set up. I dont think I will be auditioning anymore subs, I have found the ONE. These things are AWESOME. I put in San Andreas and listened to the earthquake sequence and was blown away. This was at a volume level of 1/3. They will only get better with the break in period. My wife told me everyone will have to buy earplugs now, what a compliment. I also want to say a big THANK YOU to Howard for his help when I called, so easy to talk to and very up front. If you are in the market for some awesome subs get the Speedwoofer you will not be disappointed. I forgot to say I have a BIG room and it is filled with base. I cannot wait for my daughters to hear this now.

Well I received my Speedwoofer yesterday. I set it up in a front right position next to my aj pioneer tower. I performed the denon 910w audessy set up and made some minor tweaks of my own. My wife then joined me to watch Captain America civil war. All I can say is WOW! Now mind you my previous sub was an htib sony pos. so im probably not the best person to trust for a glowing reccomendation. This subs bass was tight and explosive. The wife stated we wouldnt need to schedule any massage appointments, just go to the theater room and crank up an action movie! I took that as a positive reinforcement that this sub was a great investment. The pioneer AJ speakers now sound like a millon bucks as compared to before.

I've had my new Speedwoofer 10S for 2 weeks now and I LOVE it! I have a very challenging medium sized room that opens up to one side into the kitchen. (The dreaded "L" shaped room). The back of the room opens up again into a hallway. I've learned a lot about acoustics recently and an L shaped room is about as bad as it gets. Additionally, there's only one spot I can put a single sub, both for sound and aesthetics.(wifey influence:)) Long story short- THIS SUB IS AWESOME! It fills my jacked up room with Deep wonderfully accurate BASS. Seriously, do your research. The 10S competes with subs that cost twice as much. I would tell anyone considering another company's single $800 sub to just get two Speedwoofers.. You can't beat a multi sub setup and all of its advantages for ONLY $798 shipped!! Trust me, as soon as I can convince the wife I'll be getting another one:). I am by no means saying that one of these subs won't be enough though. It really is an amazing product at an amazing price. Check out the Audioholics review of this sub. If you're not familiar with the guys at Audioholics, get familiar:) If you care about sound:) They test $2000 subs all day long and they are blown away by the 10S's performance at this price point. Anyways, I could go on but put simply- I LOVE IT! I have to add that RSL's customer service is really outstanding! When you call them there's this crazy thing that happens-- A HUMAN PICKS UP "and" they know what they're talking about!!! I had some specific questions that were answered promptly by email as well. I got very friendly and helpful well thought out assistance - EVERY TIME:) Mr. Rogers himself was the man I was corresponding with. Seriously awesome customer service. This will not be my last purchase from RSL. I plan on replacing my front LCR's with 3 of their monitors and getting that second sub to complete my 7."2" system the right way.👍🏼👍🏼 J. Wright

I have to say you can not beat the service we have received from RSL...sound advice, prompt shipping (2.5 days to Canada) and a fabulous product. After a long trial there is no doubt that the sound quality of the 10S has been far superior to our old Paradigm sub, especially when it comes to music.

As a legally blind audio enthusiast sound is very important to me. I have pretty good speakers (Polk LSI/M) for my home theater setup. However, I never really thought of a sub as anything more than a big noise box that goes into action for movie explosions so I didn't put much of a priority on that piece of the HT puzzle. After reading a review in Sound and Vision I decided to upgrade from a Polk PSW 505 to the Speedwofer 10s. I had been happy enough with the Polk for a couple of years as it was more than loud enough for my listening area (roughly 3,000 cubic feet). I was a little concerned at going down from a 12" to a 10" driver, but my fears quickly subsided. The Speedwoofer 10s is surprisingly powerful. Using the audio setup on my Marantz receiver the 10s needed to be turned down a bit even with the volume knob of the sub set to the middle of it's range. So, plenty more power than my room needs. With the "is it enough" question answered I started playing through movie scenes and music that I am familiar with. The thing that struck me the most was how musical the sub sounds. I never thought of a sub in terms of music, but I didn't know what I was missing. Listening to the album Mama's Gun by Erykah Badu I heard subtle tones in the baselines that I didn't know existed. And hearing detail in the rumbles and shakes of movies was equally shocking. Who knew? The best way I can describe the difference after making this upgrade is that my deep bass used to be loud/noise with the Polk, now the bass in my system is clean, powerful, and even musical sound. And the icing on the cake: My wife took one look at it and said that she was happy I made the switch because the 10s "looks" much nicer. This is something that obviously never occurred to me, but it's definitely an added bonus when HT equipment is met with wife approval. I couldn't be happier with this sub. Thanks RSL.

Hello RSL: I have had the 10s sub for more than a month now. I previously was using a 1993 (!!!) Velodyne VA1012 B, but it developed a hum issue. I read the review in S & V, saw the incredible try-before-you-buy deal, and gave it a shot. The bass notes I am just now discovering in much of my music has been eye (ear?)-opening to say the least. The Velodyne did well with slow, deep bass but missed an incredible amount of transients in "quicker" notes. I now sit in my listening room and just pick random tracks from my streaming collection, enjoying the discovery of all the new bass information. As a bonus, with the crossover control I can get a nearly seamless transition from my Goldenears 3D Array soundbar and Invisa in-walls to the 10s. The Velodyne was set at 75 hz, which taxed the soundbar's abilities. Now the soundbar is free to focus on the frequency range it excels at, which has revealed a whole new level of music information coming through the speakers. All in all, the 10s has transformed my system in the most substantial manner I have ever heard. And the price??? Incredible!!! (The Velodyne set me back $699 in 1993)! WELL DONE!

Honestly this sub packs a punch! I was anxiously waiting for it and it finally arrived home last week Fri 8/26. When i connected this bad boy to my Onkyo receiver with another previous RSL sub i have, it blew me AWAY i felt the base running through the floor into my couch all the way to my chest!!! Woooo Hoooo!!! pure raw organic base with no muddiness. Im impressed with the sound, the quality, and the power this sub has. To finish my review i have to thank the guys in RSL for the phenomenal work, customer service and attention to detail they have.

My subwoofer 10S arrived on June 24 and got quickly put into service.WOW! It is impressive - it keeps up with my Magnapan MG12s nicely. I rattled my window A/C right off so down went the volume. I have lots of organ CD's which notably sound much better, but feel like real organs. As for movies, I think all subwoofer manufactures have a deal with moviemakers to show off explosions,and ominous low stuff, etc. to help sell the movies on DVDs - even Neflix. I just wish I had the space & $ to get surround sound, but your woofer puts me in the ballpark. Hope you do well and thanks much for your help on the phone.

Wanted to let you know some preliminary experience w/ my Speedwoofer 10S. Had chance yesterday evening to put on some music which I think took advantage of the Speedwoofer. Music overall sounded fuller, and richer, than I think it did before. I temper my comments with guidance that I'm not an audiophile or audio expert, but, thus far, the 10Ss is a welcome addition in my system. Looking forward to further listening, breaking in the speaker. And, eventually, adding the RSL in-wall and ceiling speakers to replace those which I inherited with my house.

First off let me say I highly recommend the speedwoofer 10s I have two and they are fast and accurate. A good match if you own magneplaner speakers, a tough feat for any sub. Read the professional reviews the only thing I'd add is I definitely don't feel I need any more low end or extension. The reason I'm writing this review is because of the amazing passion Howard has for his speakers and his company. I ordered my Sub's on Friday and July 4th was Monday so good chance I was going to have to wait for my new shiny toy. So then I get the following email from the owner of the company:

Hi Kevin,
Thank you again for your order. The warehouse was backed up today and told us it would be difficult to fill your order today. Since Monday is a holiday and they won't be working, I insisted that they ship at least one of the Speedwoofers and the wireless transmitter so you could get it as soon as possible. They did that and the tracking number is: Xxxxxxxxxxx
To track the order, please visit http://www.fedex.com/us/. A signature is required upon delivery for all orders over $500. The second Speedwoofer 10S will be shipped on Tuesday and we can get you the tracking number for that Tuesday night.
If you have any questions, don't hesitate to ask us. We're always happy to provide expert support.
Have a great weekend and 4th!
Best regards,
Howard

Ok now this is a man who knows how exciting it is to receive a new purchase and how hard it is to wait. This is a company run by a true passion for there speakers! You WILL be treated exceptionally well.

I have received the sub-woofer last week, I have installed it on Saturday. So now the so call “braking time” is over. And my reaction is … WOW !!! This sub-woofer is quite amazing and have a very impressive sound quality considering the price. The capacity of the SW to reproduce all the nuances of the lower bass frequencies is really good. So I am very happy with my purchase.

I want to congratulate you guys on a job well done. I ordered both your 10s and the svs sb1000. I already have the sb13 in my designated home theater but I wanted a cheaper sub for the living room. Since both you and svs offer the home trial (actuallt svs trial is slightly longer) I could just return the sub I liked the least. I have to say I love my sb13 and expected wind up with the sb1000 as well, but figured I'd give the 10s a shot. Well somewhat to my surprise, I sent back the sb. Its a very good sub but doesn't seem to handle the lows quite as well. I was also pleasantly surprised at how much I could feel the bass from the 10s. It was more than I was expecting from something so inexpensive, about 100 dollars less than the sb. You've got a good little sub here. Great service to boot.
