LISTEN TO THE SOUND OF LIMITS BEING SHATTERED

Included: 1 Speedwoofer 10S

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…

I want to thank Joe Rodgers, when it comes to knowledge, understanding, service and with the great customer service skills, I greatly appreciate this lost art in today's world . I own NSD SB 12 SVS I bought 3 years ago. It's been a great subwoofer, I mainly use it for music, I am a Music Person 80% of the time , I do occasionally watch movies. I talked to Joe Rodgers 3 years ago and ask him is RSL speedwoofer 10s a better Sub then SVS NSD sb 12 enclosed. He responded there both good subs and I couldn't go wrong either way. He explain that the RSL is a great musical sub first and wonderful home theater sub as well . I already purchased SVS at the time and was on a 30 day trial with SVS and loved it . I always wanted to get the RSL and just couldn't pull the plug do to this was a want and not a need . After 3 years I decided it's time but due to covid it set me back from getting right away , I had to wait due to parts on container ships. I finally received the Sub, I have 2 systems in my home, one is for all my albums,CD's and other for my home theater . I set up my RSL and knew right away that RSL was the true winner for my music needs, definitely was by far a upgrade to my system. I have Klipsch reference series R-51M towers. I listen to all era of jazz from 1920 to today and all kinds of good music. This sub totally blends in well and intensify the richness of sound accuracy. My SVS is now part of my home theater system and is great sub but RSL, I can not say enough about the accuracy and stellar punch, I was not looking for loud, but looking for precise accuracy of instrumental results . Thank you... Joe Rodgers for making this happen for ordinary American people. Bringing quality, affordability that we can have and achieve. Brent

Just received the latest Speedwoofer 10s from RSL and I’m very impressed. It mates exceptionally well with my Omega 3xrs speakers and adds the foundation I wanted , without interfering with the midrange and treble. The Omegas are exceptionally fast and the Speedwoofer is equal to the task. I had demoed a Rel 7x but that was only used for a couple hours with a set amp (different than the Belles amp/preamp combo used for the RSL) which doesn’t make a fair head to head comparison. I do think the value is outstanding for the speedwoofer 10s, to say I like it is an understatement .

Simply amazing. I am really enjoying my Speedwoofer 10s. I using bothe the LFE and speaker level connections simultaneously. Most subs in this price range don’t even offer speaker level connections and if they do, most I’ve seen make you select one of the options. Just a single Speedwoofer provides all the bass I need for both home theater and 2 channel music listening. I would describe this sub as clear, punchy, and very musical.

Simply amazing. I purchased a single Speedwoofer 10s a few months ago and Am very happy with my purchase. I am using the speaker level and LFE connections simultaneously in my setup which is not a very common feature in subwoofers at this price range. Most I’ve seen with speaker level connections make you select either option when setting up a sub. One Speedwoofer 10s is all I need to enjoy both my home theater and 2-channel music from the same setup, which includes CG5’s and CG25 center.

After months of studying subwoofers, my search is over. I ordered a Speedwoofer 10S on August 29th, and after a long voyage, it arrived on my doorstep on Halloween. It integrated seamlessly with my simple stereo amplifier (no Audyssey required), and it smoothly picked up where my B&W 685 S2's roll off. I plan to make more fine adjustments, but the Speedwoofer sounded great out of the box. I wasn't impressed with the PB-2000 Pro (despite a lot of tweaking), and even less so at the idea of spending even more, only to get just a bit more extension and output (not to mention placing a much larger and heavier unit). The Speedwoofer is almost too small to be this powerful, and in my opinion, its price is almost too low for it to sound this good. RSL customer service is also top-notch. The Speedwoofer is shipped double-boxed, but the domestic shipping carrier managed to puncture both layers and put a good scratch in the side of my unit. Right away, RSL had a new one prepped for delivery. I didn't need to wait for another one from overseas, nor did I have to go without while I waited to the replacement to arrive. RSL recommended that I audition the one I had, then to send it back (with prepaid shipping label!) after I had the replacement. Thanks, Andrew! Not only does my Speedwoofer 10S sound great, RSL's care in making things right has completely exceeded my expectations.

I have been shopping for new subs like a madman for the last year it seems. I even purchased a Monolith 10" by Monoprice as an open box item on Amazon. It was amazing, but not even close to as hard-punching and fast this RSL Speedwoofer is. So far (after the insane L.A./China shipping fiasco) I've had this for about two whole days now and I can't stop listening. The musical quality is amazing and movies don't just rumble, you are literally pressurized with Bass that gives every epic bwaaaa a whole new meaning. Instead of laughing at how overused they are, the bwaaaas are something to look forward to now. I'm so amazed with this sub. It's just gut-wrenchingly loud. I ran Audyssey and just the bass test signal had me excited. Also, Audyssey thought it was a little loud and at half Gain volume, Audyssey adjusted the sub-signal -6dB. What?! I turned it back up to 0dB and then rolled the gain back to about 40% and now I'm in the zone. Thank you guys! Soooo worth the wait! It's like a drug. Now I want a 2nd one.

I didn't see a way to edit my first review that I did a week or two in. I've now had mine for - hm - coming up on a half year, maybe?? I didn't look. This thing has to be the best subwoofer deal on the planet. What hooked me originally was the review in the NYT - a crazy place to get told about a sub. Did the rest of the reviews available. They all say it's as good as other subs at twice the price, so get two. Maybe that should be, but I contimue to be awed by this single (after reading and watching ALL the sub placement vids it ended up directly under the center front and you can't tell that's where it is with your eyes closed) - I have a surround of the Canadian brand with towers in the front, and I'll never get rid of 'em, they're phenomenal, but the big Canadian sub (now out of production) doesn't hold a candle to this thing. Whether I'm playing the P3/Dynavector, the Oppo, or simply streaming 5-channel for boom-boom flicks, the thing is just fabulous. If I'd known about their speakers when I got the Canadian ones, I would have tried them. AND the company does what it says it's going to do, period. Superb equipment, great prices, superb service. Can't ask for more.

Finally got my Speedwoofer . Got it hooked up to my Harman Kardon 3500 via the subwoofer output ( RCA patch cord ). I have JBL LX500 for my main speakers . LX500's are very good old-school 3-way speakers . I have the Speedwoofer set to internal crossover so it just takes care of the deep bass. I LOVE IT. It really adds a new dimension to the music and movies I play . The Speedwoofer is really non-directional and room filling . You cannot tell where the sound is coming from whether I'm playing music and movies . At low volume ( playing movies late at night ) , I love the full sound . The enclosure is really solid . I hear no port or enclosure noise . And the bass is not colored . It's tight and clean.

I had owned some full range T??t??s that displeased me (I must be very choosy according to them.). I shopped around for a product that would both fit within my space and give me great surround sound. (I'm getting to your product, give me a moment.) These replacements were set of smaller Ohms (another direct seller). The problem (It always is!) was non-formidable bass. I expected that and since I am an A/V guy an unacceptable situation. Audioholics had done a review and I was convinced that with your return policy I could not go wrong in a purchase. This proved true but though it's a mighty device, its bandwidth wasn't catching the RARE lower notes. So I purchased another unit from a competitor to whack the upper teens and lower twenties knowing that its speed was lesser but I was looking for thunder not definition from that unit. This works great (to me) in my small room but the Speedwoofer is the lead and it sits front and center. I am greatly pleased and smug. Now do your due diligence and do make this purchase. These are great and so is this company.

I have used this sub with my B & W 703s for a year or so now and I am very impressed. I have also used the sub with Maggie LRSs and Monitor Audio Sliver 10s with very good results. Detail and definition are amazing for a sub at this price and better than a number of higher cost options I have auditioned. I use the sub in our sunroom with the 703s since this is where I do most of my listening and also, for watching movies. The sub does not make its existence known with music that has no low bass content. When something deep enough comes along the sub produces that bass with great definition and clarity. String bass on jazz cuts sounds really fine. The sub, when properly adjusted, doesn't make the string bass notes sound bloated and fat. One final comment. If a company produces a product that costs thousands and sound good I am not impressed. RSL has produced a product that sounds really good at a cost the average person can afford. That's a much more difficult task to accomplish. Thanks RSL!

I’ll start this short review by saying I’m seriously impressed with the performance at this price point and well beyond. The Speedwoofer is in my 2.1 living room system and used exclusively for streaming movies/music, and it provides such detailed, powerful, room filling bass down to its tuning point that I’m truly impressed . I ordered at the end of 2020, and received it in March 2021. The long wait due to Covid related delays was unexpectedly rewarded with an extra year warranty and a $100 off coupon for future purchases, how awesome is that?! For reference and listening comparisons in my dedicated media room, I have multiple subwoofers with pro audio drivers that cost 10 times as much as a single Speedwoofer. With music, the Speedwoofer honestly sounds as good as any sub I’ve heard or built…which is insane considering the price and the amount of subs I’ve experienced over the years. If you’re on the fence about which sub to buy between all the major ID brands or even retail stores, nothing touches the Speedwoofer for music at even double its price (seriously buy two Speedwoofers instead). You’ll notice I didn’t discuss LFE and movie content, but I didn’t purchase it with expectations or needs for reference level playback. It fills in movie effects admirably and without any hint of port noise, just don’t expect earth shaking bass below 25-30Hz, as the response drops off fairly fast by this point, especially in a large room. That said, the quality of the bass produced never falters. So here’s yet another strong recommendation for the Speedwoofer from this guy!

After about 6 years with a Dayton Audio Sub-1200 I felt that my large room just needed something with more impact to really bring things out in movies. After hearing about the RSL Speedwoofer 10s on an HT Group I belonged to I started doing some research. In the running for this upgrade were the RSL Speedwoofer 10s, Monoprice Monolith 10 inch, SVS PB1000, Rythmik LV12F and the HSU Research VTF2-MK5. I quickly narrowed it down to the Speedwoofer and the HSU VTF2-MK5 as being the best values for the money as I felt comfortable compromising the deep bass at the $399 price point, but didn't feel comfortable with the compromises that the SVS and Monolith offered in the mid-bass range while being within $100 of the HSU Research VTF2 MK5 after taxes. The Rythmik LV12F had some complaints about port noise/resonance issues and once again at $600 I saw little point in compromising when the HSU was within $50 in price. Although the VTF2-MK5 by all accounts is a better performer in all respects the Speedwoofer 10s won out for 3 reasons: 1) Compact Footprint. I'd already had issues with kids tripping over my Dayton Audio SUB-1200 and the idea of having a solid performer fitting in less than a 17 inch cube was very appealing to me as it fits perfectly against my furniture and doesn't stick out. 2) The $399 price point made it a more affordable choice and was definitely easier to convince my wife than the $643 shipped pricetag of the HSU Research VTF2-MK5. 3) The 30 day return policy essentially made it so I could try out the RSL Speedwoofer 10s and recover every penny of my money if I wasn't satisfied. Conversely if it turned out that the HSU Research VTF2-MK5 didn't live up to my expectations/all the hype I have heard about them, I would recover the value of the subwoofer itself but would end up eating over $160 in shipping costs (cost of shipping it to me and cost of shipping it back to HSU since shipping costs are separate). It also put me in the potential position where I could compare firsthand the RSL and the HSU without having to ultimately be stuck with the purchase price of both. After giving the Speedwoofer 10s a chance to break in I can definitely say this thing moves and it's mid bass output for such a compact footprint and price point is amazing. My Speedwoofer easily outperforms my Dayton Audio SUB-1200 in the mid bass range and keeping in mind I have my gain just a hair shy of 50% on my Speedwoofer 10s and run about 90% gain on my Dayton Audio SUB-1200 to get it sounding good. Admittedly the 12 inch Dayton Audio does have a hair more response in the deep bass range being a 12 inch sub that is cranked nearly to the max, but I have to be within a few feet of the sub to even notice it. Strangely enough I am currently running the Dayton Audio SUB-1200 and the Speedwoofer 10s as dual mismatched subs which although many frown on has proven valuable in the comparison department and due to the neutral nature of RSL products the two actually blend together fairly well even though the Speedwoofer generally outperforms the Dayton Audio, the Dayton Audio still is able to make it's presence known due to it's location away from the Speedwoofer. It should be noted that my HT is in a large open area that measures 31.5 feet long x 17.5 feet wide and has 11 foot vaulted ceilings so filling this space is a challenge. I do feel that the Speedwoofer 10s would be more complete if it offered more in the deep bass area for HT applications, but understand the compromises made due to the subwoofer size and price point. Above 20 HZ though it performs beautifully and hits hard and accurate. It is well suited for music that demands accuracy (ie multiple bass drum punches in quick succession) and certainly outperforms my Dayton Audio which has all the grace an accuracy of a poor old lady falling down the stairs by comparison. Bottom line if RSL ever made a 12 inch version of this sub in the $500-$600 range I would be very scared if I were running SVS, HSU Research or Rythmik.

I bought the Speedwoofer because my system's subwoofer blew up. I did some research and it was quality at a good price and wow what a difference great sounding bass and the set up instructions are spot on my Denon AVR1706 circa 2005 never sounded better it sounded so good I bought a pair CG 5's "blemish sale" though I still can't find the blemish. I put the cg 5's as front speakers, crystal clear amazing sound, and my old m&k speakers as rear surround speakers, now I have 7.1 surround system that sounds like a brand new stereo! I mainly use it for music listening and everything sounds amazing it's like hearing great songs for the first time again. I'm enjoying the heck out it. Words don't do these speakers justice just listen to the music: classic rock, classical, jazz, jazz fusion? It doesn't matter it all sounds amazing. What a find!

I have received my Speedwoofer 10S just ten days ago after a long wait, but it was totally worth waiting. I tested it by connecting it to my TV soundbar as well as with my integrated amplifier for stereo listening. It's an amazing subwoofer. I do not think I will enjoy watching TV or listening to music without it. My wife has already told me I could order another one (in the future). I love the wireless transmitter option; I am glad I purchased it. I am going to keep the subwoofer. At the end, I highly recommend it to anyone who is looking for subwoofer. You will not regret it. And I believe you will probably be adding a second one in the future. Thank you for such a high-quality affordable subwoofer

Obviously, the last thing you need right now is yet another rave review, but yet here it is. I have what I think is a reasonably capable system - Marantz 5015, PSB Imagine T2 front pair, and the Imagine center and bookshelves for the rear. I had a PSB HD10, and thought it was helpful until after a decade it developed a 60hz buzz all its own. That's when I started hunting, and for better or worse for you folks, NYT published that rave review. That led to hunting everything I could find on the Speedwoofer. FINALLY decided to push the button and lo, you're out of stock. What the heck, I'll plunk the $400 and wait. Well, here it is for the past week or so. I've had to fiddle because Audyssey over-and under-estimates a lot in this crazy room. Audyssey set the sub at -12db, which is too much for 2.1 off the P3 or the Oppo, and not quite enough for 5.1. I've read/listened/watched a bunch of the sub setup stuff, and truly now believe. Two feet makes an enormous difference. It now disappears and the bass either comes out of nowhere or right out of the front pair. Strange phenomenon. I'm awed. The Speedwoofer is INFINITELY clearer than the old sub; I've heard from a few that there's a break-in period, but if there is I've not been able to notice. I cannot even begin to tell you how glad I am to have listened to the reviews and been patient. The Speedwoofer has added an entire dimension to the musicality of my recordings (and hd streaming music), and of course makes movies FAR more fun. Thanks you guys and ladies. For everyone else, hope you can ante up a bunch of these things.

I bought an entire 5.1 system from RSL based on all the reviews I had read and all the positive PR. I was on a budget so I opted for the CG23s as L/C/R speakers and a pair of ceiling speakers for my rear L/R channel. Naturally the subwoofer was going to be the 10S given the value they represent. I got the wireless version and it works flawlessly. The sub has plenty of punch to rock the house! So much so that I have to turn the volume down so that we do not disturb the neighbors! It also does a great job as a 2.1 system for listening to music. The sub blends seamlessly with the CG23s to give me a full range for my music.

I don’t write reviews but felt compelled this time. It’s 2/14/2021..... I ordered my 1st speedwoofer on 5/5/2020 when production was slowed by the pandemic. In an act of blind faith I orders a 2nd unit 10days later having no 1st hand experience with them. I had some some email correspondence with Joe before my 1st purchase about picking up a b-stock to test the water, what a great business man, I wish some others would take notes on how this company operates.... kind, helpful and legitimately interested in the needs/wants of a potential customer. Skip to today... I’ve been using these woofers for a while now and I’m happy to report that they are phenomenal. I worried that a 10” woofer wouldn’t be enough for the large room they live in (16x36 with 9 foot ceilings), honestly, one would have worked great but I’m so happy to have the extra overhead with the pair. I’m a two channel guy and live for clean, accurate, punchy music. I really don’t think I could have made a better choice. The fact that I had such a great buying experience is just icing on the cake.

Full disclosure: since you are out of stock on Speedwoofers on your website I purchased a SVS SB-2000 last week for $500 and it arrived yesterday, I spent last night tuning and tweaking it and have it connected to the same receiver that my current Speedwoofer is connected to. I much prefer my Speedwoofer and I have now gone through the SVS, an Infinity R12 ,and a JBL 550P and the Speedwoofer outperformed them all for tight, punchy, full bass,. I am generally allergic to buzz and have read many of the articles of acclaim that your company and products have garnered, but I have a keen ear and your Speedwoofer is simply a fantastic component. Congratulations on creating a truly iconic product whose reputation is well-deserved.

Excellent subwoofer. Well worth the wait for the order backlog to clear. These things are fabulous. I bought two, plus one of the wireless transmitters. One Speedwoofer is probably enough for most people. Two takes it to a completely different level. Don't know why all the competitors cost so much more. If you are looking for a subwoofer under $1000, this is the one (or 2!) to get.

Wow... I bought 1 for my small (11' x 10.5') home theater room and was blown away by the quality. I immediately, upon hearing how good it was, ordered a second one for my room and I couldn't be happier. So crisp and clean but yet, chest and hair vibrating goodness. Don't even hesitate. Buy a couple... And yes, this is 100% a real review from a customer... very satisfied and will definitely buy more in the future

I would like to thank you for a quality woofer. I chose this because of the reviews and I’m so glad I did. I knew the sound I wanted but couldn’t explain it. My boyfriend freaked out when he hooked this up. Was surprised that I had made such a great decision. I was hoping that I wouldn’t have to return it. I had a budget at first but after I read the reviews I decided to buy it. I listened to a Sonos impressed but didn’t want to spend that amount of money. This to me is all that and more. I’m hard to please but it was a pleasure to purchase this. These reviews are real . Trust me. Mari

For the past 8 years I have been using 2 Bic F12's....because, they were cheap. For movies, they were adequate..for music, they were barely passable. I remember quite well from my days in car and home audio sales and installation that systems I designed and install with 10 inch woofers always sounded cleaner than those with 12's. Those systems were just more accurate and had a more solid bass response rather than the ba-boom of using bigger woofers. I just upgraded from my 30 year old MB Quart home speakers to some new Q Acoustics 3030i and a 3090i center...those 2 F12's really showed their shortcomings after that. So based on many reviews and my experience with 10's I ordered a Speedwoofer 10s. I got a "B" stock white one at a great price...it came in less than a week...packed super solid. I can't find a blemish on it and it is just beautiful with the white Q Acoustics mains. And, its heavy and just exudes quality. Now, my original intention was to get another in a month or two....no need. This thing is just remarkable. Its fast, its clean...its unobtrusive. It even smells good. Anyone having a doubt that a 10 cant run circles around a 12 need to give the Speedwoofer 10s a try.

I bought a CG23 5.1 package with a Denon x3700h from RSL. Their customer service is second to none and they spent time to help with setup tips for optimal performance. The speakers sound clear and clean, the piano gloss is fantastic, and the Speedwoofer performance was startling. Clean, rich, full bass with tons of power. I’m very happy with my setup, it is everything I was hoping for, so glad I went with RSL. I’m looking forward to adding another and making it a 5.2 when they get back in stock,

So I originally got a pair of SVS SB1000 for their trial run in the hopes that I can get in on the pre-order for the 10s during that window. Time was running out for the SVS but thankfully, RSL came through and sent me the two I ordered. Needless to say, as soon as I heard them, I immediately packed up the 2 SVS subs and never looked back. Holy Crap! A pair of these was everything I wanted in a sub. Punch and Rumble baby!

I only play music on my system. And it it is all vinyl on record changers. The addition of this subwoofer has greatly enhanced my music enjoyment! I own Wharfedale speakers and thought they were great with the bass. This just made it better! Thank you for making a great product!

I recently acquired this subwoofer and have it paired with my Axiom M22 bookshelf speakers in a 2.1ch configuration for a 1000 cu. ft dedicated music only room. After I had everything dialed in and calibrated with my receiver and found the perfect location for my sub, I played some tunes consisting of Jazz, Rock and mainstream Pop. All I can say is this subwoofer truly delivers. Nice, tight, CLEAN bass with a LOT of chest punch, especially for music. I also tried it with movies and couldn't believe the LFE was coming from this 10 inch sub. In my small room, I measured output down to 18-19hz. In short, it has both the qualities of a sealed sub (tight and clean punch) combined with the power and authority of a ported HT sub. In my very small room, the output is more than I will ever need. I've owned other subs from other prestigious and well known internet direct companies which I will not name here. These subs cost me almost twice as much as the Speedwoofer 10s and I can confidently say that none of them beat the Speedwoofer 10s at THIS price point. This is what you call value. Thank you RSL for making such an excellent product. Also a special shout out to the AVS forum members for recommending this subwoofer to me.

I was looking to add a pair of subwoofers to my 2 channel setup. I spent a lot of time researching but you never know what you're getting until you actually hear it in your own room connected to your own system. I hate bloated, flabby, boomy bass and while I know the room plays a big role in the sound I can honestly say I'm blown away by the sound quality of the Speedwoofer. Turn it on and give the caps a bit to charge, play some tunes through it for a couple of hours to break it in and with careful placement and adjustment you'll be rewarded with deep, tight bass that blends very well with the rest of your system. Thanks Joe, I know I had a lot of questions leading up to actually buying something but I hate packing an item back up for return. No worries here though, the boxes have been thrown out!

I added a white speedwoofer to my Q acoustics 3050i 5.1.4 setup. My application is 70% movies and 30% music. This subwoofer really delivers. Tested this sub with test cd for different frequencies and surprisingly it had significant response down to 18Hz. This is very helpful in movies like Underground 6 on Netflix. This have very tight performance which is very helpful in music. All in all I felt the subwoofer had traits of sealed box as well as ported box. Overall this sub Integrates really well with my Q Acoustics setup and serving my medium sized room well for movies and music.

RSL team, I paired the RSL Speedwoofer 10s with some Q Acoustics (sorry, they fit the decor) 3020i and 3090ci speakers and am completely blown away with this subwoofer. I needed a relatively small woofer and wanted deep range and the Speedwoofer exceeds my expectations in all areas. It is transparent in music and a force to be reckoned with during movies. I love the precision and musicality of this sub. Well done!

Equipment: NAD 3020v2 Hybrid Amp, ELAC Uni-Fi UB5 (pair) Room Size: 15' x 12' Sub Settings: Onboard Crossover @100hz, Volume 20% Habits: 85% music, 15% movies Other sub owned: Hsu Research VTF-2 MK5, ELAC 3030, ELAC S10EQ, Polk PSW505 I knew I was in trouble when I plugged in a live LFE line into the sub (thought it was off) and scared the s**t out of me at 50% volume. The ELAC Uni-Fi pair sound good on their own but still need reinforcement on the bottom end for movies and music. First song I tested was Black Parade (Extended Version) by Beyonce and 50% sub volume was way too much for my tastes but damn was it loud clean bass; I dropped the sub volume to 40%. Next song, Are You Even Real? by James Blake, dropped the volume down to 30%. I settled on 20% by playing So What by Miles Davis since I knew how that was supposed to sound. Then it happened, the bass integrated with the bookshelf speakers and sounded non-directional.To make sure I did not sell myself short on bass I played the intro of the movie Edge of Tomorrow and yeah...the bass is definitely still there. Having owned other subs in the $500 - $800 price range, the 10s manages to outperform other more expensive and physically bigger subs. Buy this one (or two) and do not look back, you are getting serious bass for relatively little $$$!

Thank you for building a fantastic product and offering it at an extremely fair price. I’m not sure what’s going on, and I consider myself a fairly experienced user, but your single Speedwoofer provides more satisfying and equally impactful bass as my JL F112 (sealed box-$4,000) in my room. The articulation and air moving capability are similar but the way your sub blends with my Revel Performa 3 speakers is superior. Absolute winner!

First off I'd like to thank Joe for getting back to me at the first of May during this pandemic and also answering other questions I had during the month,which led me to receive my pair of Speedwoofers. I've had a pair of mismatched vintage M&K subwoofers that I've owned since new. One was from 1985 and the other was 2000 and were just not sounding as good as they once did, back when I had my Magnaplaners. Then the amp went on the newer one and it was time to start shopping online for some new ones. I started checking on different forums and then learned about RSL and there Speedwoofer 10s, also found some very excellent reviews for this mighty mouse subwoofer 10in. So I got on RSLs website to find out that black was on back order. During this pandemic I've been listening to a lot more music. I've got a integrated KT88 tube amp,Shiit Gumby dac and cd transport which puts out some wonderful sounding music to my Heresy III speakers,but with out my subs in the mix, it was just not the same. Sure there were other company's,but I liked what RSL had to offer. 30 day home trial, free shipping to and from and no tax. What more could you ask for ! Since having a tube amp there is no preout to hook up subs,so I needed one with high level inputs,plus it has rca in and outs ,also has a real phase knob not a switch. This checked all the boxs,so I pre ordered a pair on May 7th and now the wait. Come June 15th they showed up at my door and started moving stuff out of the way to place the Speedwoofers behind the Heresy III. I've been wanting to hook these up in stereo,left output/left input and right output/right input to help augment the Heresy's, since they only go down to 58db. Went to turn on and got the nasty hum. I use to work in a local audio store in the late 70s and went through everything I could think of from back then to eliminate it,so then I was down to only having the speakers hooked up to the amp,no pwr cord or interconnects and still the same problem. I gave up that evening and thought about it threw the night and remembered that it could be a grounding issue. Got up the next morning and took some left over 14 gauge speaker wire,crimped on some spade connectors and attached to one of the screws on the plate amp and then to gnd lug on HT amp,since tube amp has no gnd lug and walah,all is silent,also did the same for the other sub. I went to set up gain at 12 o'clock,set crossover to 80hz and waited on phase till I got the others right. Went to put in a Dave Brubeck live cd which has a song with a stand up bass and wow to much bass,had to turn them down to about 10 o'clock. To set phase, I've been able to stand over sub and hear the difference as I turn the knob, till it comes in strong and clear. Now I sat back and could not belive what I'd been missing in bass. These subwoofers are very musical,very nice sound with kick drums and stand up bass was great ! Nice thing about the plate amp,is that I was also able to hook up my HT receiver LFE out to Y cords to input and output to y cords to the input to the other subwoofer and just have to switch the crossover to LFE when watching movies,then when listening to music,switch it to internal crossver. I highly recommend the RSL 10S, integrated well with both HT and tube amp. Now it's time to dust off the movie U-571 and listen and feel the depth charges go off, also a DVD of John Fogerty, that has a great drummer Kenny Aronoff slam on the drums. Again I'd like to thank Joe and his staff for all ther hard work during this pandemic and letting me enjoy my music and movies all over again.

I have a townhouse with neighbors on both sides of me. I used 3 different brands of subwoofers and neither of my neighbors has complained about the sound. My 10S has arrived. Wow! What sound! And, within 2 hours of use, I received phone calls from both neighbors asking me to turn down the thunder! Please do not waist any more time reading this review. Instead, get out your credit card and order the 10S. You will thank me.

I just received my Speedwoofer last week and placed it into my humble system. It is paired with a couple of well-burned-in first-generation CG-3s that have had to make due with a cheap sub I purchased a few years ago that finally gave up the ghost, so to speak. Until a week ago, I lived with all the much-harangued issues that tend to come with sub-standard subs and dealt with it by simply turning both the crossover frequency and volume way down to just fill in the very lowest end. That said, with the sub off I enjoyed the wonderful sound that emanated from the CG-3s on their own, I just used the sub for a bit of punch when watching movies, etc. Things have certainly changed! Preferring a simple stereo setup, I have my new Speedwoofer linked to a Yamaha A-S301 via a new Audioquest Greyhound sub cable using the Sub output port. Oh the Irony! I am now in a position--being an apartment dweller--where my humble system has the ability to literally destroy my neighbors cherished belongings! I literally have the volume of the Speedwoofer only 1/4 of the way up and feel every kick drum punch--bass in Jazz recordings is realistic in timbre, bloom, harmonics and decay. It has added so much to the mid-range presentation, as well. All this without the slightest indication of strain or distortion. All the boominess is gone. Bass is tight and quick. Fair warning, Godzilla's roar at half-volume will literally blow your head off! This is how you build a subwoofer! By the way, I somewhat apprehensively ordered a white one (the rest of my system being black) and was very pleased with how aesthetically appealing the look is with the white fabric grill. It certainly has the spouse approval factor covered. Thanks, Joe, and thanks RSL!

5 stars! I bought the Speedwoofer 10S to replace the high end unit I purchased with my home theater redo. Several reviews convinced me to get it a try, despite the really inexpensive price. Now I call it the greatest value in my system. This sub was immediately better and blended strongly and well with my (otherwise) really good system. When the amplifier in the sub went down, RSL was direct, courteous and generous as I was just a bit out of warranty. They sent the replacement amp for free, the install was easy and the unit is really welcome to work (espcially during this shelter in place). Thanks, RSL, love the unit and your service was outstanding.

I've had a Hsu sub for years. It's been one of the best subs I've ever owned. I won't knock it at all here. But, in saying that,it was not going to be enough for my new home theater. I started looking online for a replacement. I kept seeing adds for RSL speakers. So I investigated, and researched for many days. Long story short, I reluctantly bought 2 speedwoofer's. My first concern was price, basically I could get 2 of these for thee cost of one other sub. Second was, would it fill my room? After sitting on these for about a week we finished our new room. I got everything hooked up and started the fun. At first I thought I really missed my Hsu... But after 2 days and some placement rearranging I was dead wrong. These things are magical. I was in awe of the bass and tones these produce. Music is lightening fast and clean. Movies are loud and realistic. I'm almost wonder if 2 was overkill? I'm so glad I found RSL. There subs are phenomenal, no hype, just as described. I keep thinking I need to turn them down. My house has never had this much shake before. This us an excellent product. True to claims and much better than expected. Thanks RSL.

I purchased my Speedwoofer 10S in October 2019, from RSL's outlet. Although "B" stock, I could see no imperfections. Shipping was both free & fast. I ordered it on a Thursday, it shipped the same day & I received it on Monday (on the opposite coast). Used cable to LFE input; Phase at 0; internal crossover to bypass. It was clearly too loud with volume at 12 o’clock position. Turned down to 10 o’clock & ran Audyssey (Denon AVR X4300H w/ MultEq XT32), but it would not proceed until sub volume was at 9:00 o’clock position. When done, Audyssey results showed sub level set to -12, which I read is the limit of adjustment, which means I should run again with sub volume at 8:30. Despite the resulting low signal from the Denon, I have never had an issue with the Speedwoofer not waking up. Based on where I had it placed (rear of 12'x15' room, behind couch), was concerned I would hear the subs location, but you would swear the base is coming from the front/mains & blends very well with them (Monitor Audio S8; 35Hz-25Khz). Although running a 5.1 setup, I was mostly concerned with music quality & was not disappointed. The bass has a fast, clean punch (for both music & movies). I had a few questions both before ordering & after running Audyssey, and received fast, complete responses (directly from Joe Rodgers). Unfortunately, after about 5 months of use, the Speedwoofer's amp failed, but I received a response to my email (from Howard Rogers) the same day & a replacement amp was sent out that day, with free delivery. Again, great customer service! The fact that I didn't do a review until after this happened indicates that I am still very happy with my decision to go with the Speedwoofer & do business with RSL. Will be looking at their speakers/Speedwoofer for another room. Great subwoofer (particularly for the price) & great customer service.

I purchased this subwoofer back in January 2020 with the wireless transmitter just in case I move the subwoofer to a different location. I received the speaker pretty quick from the time I placed the order till the time it was in front my door was about 3 days great job RSL! The box was very well packaged and it was double boxed for extra protection. The fit and finish was excellent no scratches no dings. I used a subwoofer cable to connect to the LFE input. I ran Audyssey set the volume to half way but it was too much so I backed it down to about the 10 o'clock position and I was on my way to finishing uo my set-up. This subwoofer packs a punch when I'm watching movies. I watched "Saving Private Ryan" and the opening scene when they land on the beach all I can say is "WOW"! Everything in my room started shaking and Im not even half way on the volume. I want to thank RSL for producing a very fine subwoofer. The best part of this is that it didn't cost me an arm and a leg to get a great sounding sub!

I bought SVS SB-2000 because it was on sale ($650) with the thinking that it may be better than the Speedwoofer 10S for music. To my surprise, I need to put the volume about 25% more in the 500W SB-2000 to get the same effect as the Speedwoofer 10S for both music and movies. My son, who is a concertmaster for a youth orchestra, and I cannot tell the difference in sound quality for music. I return the SB-2000. The Speedwoofer uses less power (good for the environment), provides a good base quality equivalent to SB-2000 and costs less. Thank you RSL.

Well I'll start off saying I just love all kinds of music and enjoy taking time out of the rat race to enjoy listening. I looked at all sorts of subwoofers and willing to spend much more to be happy. Glad I didn't spend more. Two Speedwoofers are plenty and sound amazing!! They are fast and hit firm. I haven't even spent but 5 minutes adjusting to match to my Jamo towers. These blend so well and add the depth I've been wanting. Very happy customer!

I've listen to very few sub that can play well with Magnepans. This blends seamless. This is some of the fastest, cleanest, most articulate bass I've heard. I've heard subs 5x this price that can't do music this well. It can also hit hard for HT work. I have never heard better value for money in a sub. I've never heard a sub this good that I would say is valued priced.

I’ve only had the Speedwoofer a week (it is not even broken in) and it is astounding. For 20 years, I believed that I had a 5.1 home theater system. Immediately upon hooking the Speedwoofer, it was laughable that I had thought I had a subwoofer. The Speedwoofer projects and disperses bass making it a sound and a force in the room. And this is accomplished with no distortion The Speedwoofer has created an altogether new and very special home theater environment. It will be very disappointing and nonsensical to ever again go to a movie theater. RSL has surpassed itself again,

This is truly an outstanding subwoofer. It plays beautifully for both music and movies and has plenty of headroom. It strikes an incredible balance between finesse and ferocity, handling delicate classical music, thumping hip hop, and explosive movie tracks with ease. It also blends flawlessly with my CG3 and CG23 speakers. The wireless kit and auto on/off works surprisingly well and I have yet to experience a disconnect. I’m using this in a room size that many would say necessitates something larger than a 10” sub, but I welcome them to come listen to what this has to offer. I largely went with a 10” for the size and aesthetics, but after spending time with it, I truly believe RSL’s claim that this can hang with many 12” subs on the market. After researching many options on the market, I’m very happy I went with the Speedwoofer.

Firstly, I have been an amateur audiophile enthusiast for nearly 50 years now. I've gone through many brands through the years. With that in mind, here is my story. I received the speedwoofer 10S about a month ago. I did not immediately hook it up because I was gifted a very nice subwoofer (at 2x the price) by by brother. I was lucky enough to have 2 rooms for viewing and listening. Last night, I set up the speedwoofer in my media room, and the other larger (cylinder shape sub) was already in my living room. So, to test the bass, I used the first minute of "Live, Die, Repeat". In the living room, We could feel the bass very strongly, as this section is below 20 hz. Then my son and I went to the media room, same movie, same level, using my Radio Shack sound meter. This time, we not only felt the bass, but there was a sudden "BOOM" sound that was not present with the other sub. We both jumped up, looked at each other, saying 'WHATTTT!". We did not hear that with other sub. The sound and impact was just there with the Speedwoofer. Yes, the other sub may have gone a tad bit deeper, but the speedwoofer was spades above it for both music and movies. Needless to say, I love the 10S! The downside is that I have to save to get another Speedwoofer. Great job, RSL!

I'I've been an audio enthusiast for 50 years, and I've been around and owned all sorts of respected audio equipment over the years, including McIntosh, Bozak, Apogee. Adcom, Yamaha, Thiel, JBL, Marantz, Paradigm, and others. I've been around the audio block, if you get my drift. I, like most other audio hobbyists, have experienced the hype and flowery ad copy that abounds these days promoting the latest and greatest equipment. I started looking for a new subwoofer a few weeks ago, and I considered several options. My criteria was narrow. It needed to be musically accurate, it needed to be fairly compact, it needed to be capable below 30 hz, it needed to be reliable, and it needed to be easy on the bank book. The Speedwoofer 10 S ticked all of those boxes. I chose wisely...this subwoofer is everything that RSL said it would be, and then some. The bass is articulate, eveloping. punchy when it's supposed to be, and never bloated or boomy. I cannot imagine a subwoofer performing than this one is at 4 or 5 times the price. It's impeccably built, smartly designed. and sublimely musical no matter what the program material is. Well done, RSL!

Let's see. I have been into stereo since 1966 and into home theater since 1992. It seems I purchased 5,891 sub-woofers to tame that bass beast for both music and movies. Never satisfied, until now. Movies now have the impact without sounding bloated. Watching one of the remakes of Jurrasic Park bought out the excitement of the movie with those big guys sounding official. But the one thing that kicks my tush was music. Being a serious part-time musician for more than two-thirds of my adult life, I know what instruments sound like. Watching Simon Phillips via Youtube strut his stuff on his amazing drum set was unreal. The drums were authoritative and punchy. My SACD's and CD's were all musical without the overextension of the bass Thanks, RSL I am in bass heaven!!

It is a well known fact that Audiophiles have a good vocabulary. This characteristic exaggerates the performance of equipment being reviewed once too often. Occasionally a piece of audio equipment deserves bombastic words of praise and in my opinion the Speedwoofer10S is where it fits like a glove. Many products carry names that are not justified by performance.The Speedwoofer justifies it quite well. First, a Subwoofer is expected to start and stop quickly during transients which the Speedwoofer excels in. This characteristic makes it sound very tight, focused and never boomy. I purchased this subwoofer after owning products that cost in multiples, this $400 subwoofer replaced a $1100 high end unit. I put it to test from Classical, Blues, Jazz, Rock to EDM tracks that had some of the best transients and bass frequencies that can either make a subwoofer great or a complete failure. Speak to Me, the first track on Dark Side of the Moon is a good test where one does not hear anything for the first 7 to 10 seconds on most subwoofers but the Speedwoofer was able to reproduce the recording in the first 3 seconds, the bass is supposed to dip to the sub 10Hz levels as mentioned in many audiophile reviews. Next, it excelled in transients from classical music and movie soundtracks. I also tested it with Fourplay's Fourplay and Between the sheets CD where the bass was tight and focused. It was able to reproduce with clarity the drum lines on Where do you think you're going track of Dire Straights album. I tested it with Chesky records The Ultimate Demonstration Disk and was able to hear all that was claimed by Mr Chesky for accurate reproduction of bass resonance. It was equally at home showing off how good it was on Rihanna's EDM tracks. Now to say how it improved my overall speaker quality, I tested it with Riding with the King by Eric Clapton and was able to hear a clear and well defined Mid range that I had not heard before.The Speedwoofer is one great product that deserves all the praise. The best Bang for the Buck I should say. If there are any cons it has to do with my own issue of ground loop which was solved by eliminating dimmer switches in the audio room and some grounding with a simple piece of wire. But, it is a very sensitive piece of equipment that needs real fine tuning so be patient and take your time, in the end it will be worth it. It is so powerful that I have the volume knob at the lowest possible level (maybe with a pure Class A Tube amp it may be so). Lastly, the after sales service is out of this world. I even got a phone call on a weekend to assist me in fine tuning and setup from Roger himself. It has been a pleasure of a purchase and intend to use it for a long time to come. Thanks RSL.

Just purchased my 2nd Speedwoofer 10s and all I can say Is my smile just got bigger having 2 of these in my theater room. I actually had to turn them down some. Having 2 Speedwoofers is the way to go as there is no nulls/dead spots in the room anymore. The room is very well balanced now and shakes the sh** out of you when they hit hard. They do play low as I have the HSU VTF-2 MK5 upstairs in our large family room which I'm very happy with too. I used a test cd that came with the HSU sub which has 16hz tones in it and I could feel those with the 2 speedwoofer 10s I have. Very impressed and If you are thinking about getting a speedwoofer 10s dont think about it just do it. Joe, Rodger and the team I just want too thank you for making such great equipment that us average Joe's (no pun intended Joe) can afford and enjoy. I saving up now to get some CG23's for the family room.

I received this subwoofer quickly... thanks for the fast shipping. It was very well packed and protected. There is no fancy box with pretty pics and colors... just a well constructed plain box... and it was double boxed, too! The finish on this subwoofer is good. The textured surfaces don't show dust, etc. like the "smoother" finishes do. The grill cover is nice. The finished product is very good. I bought one of their "Grade B" subs which shaved $30 off the price. I looked for cosmetic defects but found none. The plain Jane box and the exterior finish show that RSL is putting the money into the design and therefore into audio quality, rather than into a fancy, shiny, pretty box (don't get me wrong here... I'm saying it looks just fine). I have to agree that it puts out clean bass like a 12 inch subwoofer. The first evening I had it, I watched TRON: Legacy. Wow. Seems like the whole movie was filled with bass from low rumbles to loud thumps... and the sub handled it all wonderfully. The movie "Oblivion" is next on my list. This sub could be sold for about $500...maybe more. But RSL's commitment to affordability, performance, and online direct sales enables them to offer these at $399. Their return policy is excellent. If you are looking for a subwoofer, give this Speedwoofer 10S a try. I think you will be very satisfied. Thanks, RSL ! ! !

The RSL speedwoofer 10s is an awesome subwoofer and i couldn’t be happier. I previously owned a episode evolution subwoofer until it dries about a month and a half ago. I decided to try out the speedwoofer because of the great reviews and the generous 30 day trial. I wasn’t disappointed. I had some problems with the Audyssey room correction so i reached out to RSL and Joe Rodgers the owner personally helped me through the process of correcting my system and making it sound great. Great company outstanding product.

I've got a modest mid-price set up with a Marantz receiver powering (5) B&W speakers. The two main L/F floor standing speakers with their dual 6" woofers were not cutting the mustard in my large basement. Since I don't have an extremely expensive set-up and budget is always a consideration, I new I had to get two subs. I narrowed the choice to HSU, SVS PB-1000 and the RSL Speedwoofer 10s. I pulled the trigger on the RSL units as all the reviews I read were great and the sub is less expensive than the aforementioned competitors. I've been completely satisfied with the subs. I did encounter a hiccup with each sub due to a known amp issue on earlier models but RSL's service was great and I was shipped replacement parts very quickly and the repair was easy as well. For the money, these subs are terrific. I might add two more in the future.

I considered a wide variety of subwoofers to mate with my Magneplaner 1.7i speakers. Many experts claim that these speakers are so fast and clean, that finding a sub designed to keep up is virtually impossible. Based on the overwhelming number of positive reviews, I decided to give the RSL Speedwoofer 10S a try. I connected the speaker, ran my Audyssey set-up, and was blown away by the sound. The Speedwoofer 10S blended perfectly with my Magneplanars to produce smooth, full audio with none of the booming associated with less precise subs. I honestly didn't expect the sound to be improved to such a degree. If you are on the fence, I suggest you try the RSL sub. It is amazingly musical and warm. If it can mate with my Magneplanars, I'd bet it would be a good fit with just about any speaker system made.

Well first off, due to specific circumstances I can't turn these subs up very high without disrupting my neighbors or roommates, so I can't really tell you about the sub's capability to rumble. What I can say, however, is that the sub has been almost impossibly tight from day 1. I have never heard bass this smooth before in my life, and as someone who listens to music a lot that is a very good thing to have in my book.
