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 am located in Canada, so hopefully my review will help potential customers north of the border. There will be two parts to my review: the order process and the Speedwoofers themselves. Order process: First, email correspondence with Joe was fast, professional and exceptionally detailed. In particular, when I asked about shipping costs, I was given an outstanding explanation of how shipping is calculated along with estimates for my address. Second, I was asked to choose how many Speedwoofers I wanted to order (2), the color (black), and whether or not I wanted the wifi modules (no). Third, I was promptly sent an invoice via email to complete the order. My order was placed in the summer (June or July) and I received the Speedwoofers via FedEx in October. I was able to pay the customs fees online via an emailed link from FedEx. The shipping time from California to Nova-Scotia was exceptionally fast (less than a week). The SW10s were double boxed and undamaged. Speedwoofers: First, some background information. I had previously been using a Paradigm PW2200 v1 (12", class AB, very large sub) as well as an SVS SB1000 (non pro, 12", sealed, class D). So these are my points of comparison. I listen in a 2.2 channel system (FL, FR, 2 subwoofers in a stereo configuration). My towers are Paradigm Studio 80 v1. I do not use high and low pass, but use the subwoofers as "bass enhancement" with the towers in full range. Out of the box, I was not impressed with the SW10s. They sounded boomy, boxy, and lacked the warmth and tone of my older Paradigm sub. After a week of experimentation, I contacted Joe to voice my concerns and we shared some back-and-forth as to how I could resolve the issues. Long story short, I was able to isolate the problems. First, in my room, the SW10s had to be placed on the outsides of each of the towers (away from the sidewalls and corners) and toed in slightly (about 30 degrees) towards the listening position. Second, the phase had to be set at 180 degrees, which was completely opposite from both the Paradigm and SVS subs which were both at 0 degrees. Finally, these subs really just needed some break-in time. Once properly set up I was very impressed with the subs. They are fast, powerful, tight, and dynamic. They blend exceptionally well with my towers (better than both the Paradigm and SVS subs) and move a lot of air for 10 inch drivers. The best thing about these subs in my opinion is they do not have to be set loud to create the low end presence I strive for. In my case, I have each set to about 9 o'clock each for volume with the crossovers at about 100hz. When people ask me to describe how the subs perform, I tell them they sound like a very well-tuned car audio subwoofer system; i.e. fun to listen to. Finally, I would like to add that the most important part of this entire experience for me was the personalized service I received from Joe and RSL. I really wish other brands would learn from this business model to improve their service. Thanks again Joe!

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 v
