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…

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

Update to my November 12th review.....I just couldn't help myself...I bought another one. Hopefully Covid-19 will be tamed in a few months or so, but now I probably won't leave my theatre room anyhow.

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!
