Help us to reduce or eliminate the return fee!

Our return fee is in place for the sole purpose of protecting the Speedwoofers’ industry-leading performance and pricing. The cost of one-way shipping for a Speedwoofer ranges from $40 to $150. Double that and add a substantial cost for repackaging and recertification, and it becomes obvious why returns have such an impact. This holds true for ALL consumer-direct products. So please keep this in mind wherever you shop, and support us in the fight to eliminate the Speedwoofer return fee.

The two leading causes of Speedwoofer returns continue to be simple over-ordering and spatial constraints. As such, we would like to ask you to kindly consider the following before ordering:

  • Measure twice, order once! Please measure your intended subwoofer locations to ensure the Speedwoofer will fit. Then measure again!
  • Check with your family members! Make sure the Speedwoofer’s aesthetics are acceptable for your home.
  • Order LESS! That might sound strange, but if you aren’t sure how many Speedwoofers you’ll need, start with just one. We know that the affordable price makes multiples even more compelling. However, we would rather build your system to where it needs to be, than have you pay return fees later.
  • Ask for guidance! We are always happy to answer questions and make recommendations. No question is too big or small.

We’d love to see the return fees disappear. Together, we can make it happen!

Thank you and best regards,

The RSL Team

Speedwoofer 10S MKII

Overview

The Speedwoofer 10S MKII takes the multi-award-winning and revolutionary performance of the original to the next level.  A brand new RSL XDR™ series (extended dynamic range) proprietary DSP amplifier design, delivers even more peak and continuous power than ever before – 400 watts RMS with 1020 watts peak. The XDR™ amplifier now offers selectable dual mode DSP for a more optimized movie and music experience. Select movie mode (LFE) to use the MKII’s extra power for deeper bass extension and higher output. Music mode sets the performance to match the original 10S performance but with more power and greater dynamics. A new rear-vented Compression Guide™ tuning achieves the same class leading performance but with reduced air restriction and port noise.

Amazing piece of hardware!

I went from a Klipsch sub to RSL Speedwoofer 10S and the difference was clearly heard. Money well spent. Great service , prompt delivery and an exceptional sub .

Ridiculous Value!

Love these subs...period. Got two and we're rocking. All genres, all volumes, fantastic! Only gripe, update the logo...I don't need the "Speedwoofer" on the front, maybe just a tasteful logo. These guys speak for themselves.

MID-FI END GAME

This subwoofer is a very worthy contender in the subwoofer market. In my listening space (14 x 12) one of these is more than ample. You may want 2 in a larger environment. I'm impressed with the technology of this subwoofer, as it appears to provide the best of both the sealed, and ported worlds. The amp provides every feature to dial it into. the room and the main speakers and does so seamlessly. As far as quality in build, very decent, regarding the fact that there is a price point that needs to be adhered to. Sound quality of these units do not need to adhere to anything, RSL has done a fantastic job of bringing all this together at this price point. The actual bass that these produce is some of the most impactful, tight, clean, natural, distortion free bass I have ever heard.
I have Velodynes , Thiel, SVS, & Cambridge , all good subwoofers, but not anyone of these will embarrass the RSL Keep in mind that every unit I mentioned is at least 2 x the cost, with some of the units being up to 8 x the cost!!

Nice bang for the $$

Heard about this product couldn’t find anything negative about it so I ordered it and I’m happy with it thus far. And being a veteran I got 10% off so I got it for $404 and I’m reporting this on Veterans Day today. It’s so good. I might have to get another one.
