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.

10S MKII bundle with CGM3 bookshelves

I thought my Bose 301 series v with a Polk Audio PSW10 sounded great...I have been educated on sound quality. I replaced the Bose and Polk match up with the RSL bundle. Boy, am I blown away! Just too thrilled with the 10S MKII bundle. I live in an apartment, so can't crank up the volume but even at low volume, the bass comes through nicely after setting the passover, etc. My vinyl collection sounds just the way it should. Shipping to Ottawa Canada was timely and landed cost off bundle CAD $1279 well worth it. If you're thinking about these speakers, don't hesitate.

Really adds depth and richness

Setup couldn't have been easier, apart from a touch of fussiness with the wireless connection.

I listen mostly classical and jazz in a near-field setup, no EDM or anything like that with a heavy bass emphasis, and I don't have a well-treated listening room, just a cluttered office. My stereo speakers are ELAC DBR62s.

It took me a while to dial it in, at first I was getting boominess and weird bass peaks. Doing a room correction using my Wiim Amp Pro resolved much of that, and the sub now blends seamlessly into the overall audio.

This is my first sub so I don't have any basis for comparison with other subs, but I am VERY pleased with the added richness the Speedwoofer provides, and when I A/B my music with and without the sub I can't imagine going back.

I am very happy with the Speedwoofer, and the quality for price. I wouldn't have bought a subwoofer in a higher price range, so I am very happy with what RSL can provide at this cost.

The Truth

Honestly, I'm blown away by the 10S MkII. I am pairing two of these machines with a set of Wharfedale Lintons powered by a Schiit Vidar, Bifrost DAC, and signal coming from a Wiim Ultra. These subs are a huge step up from the SVS SB1000, both in power and musicality. I didn't know what I was missing... but now there's no going back (and I only have them turned up halfway, with gain set to -7 db in the Wiim). The bass in rap reminds me of my car audio days, rocking twin Fi Audio BL 12s (iykyk), but in rock, classical, and folk, the bass is tight and crisp, not overpowering. Perfect.

WOW

I got my hands on the Speedwoofer 10S MKii a couple days ago and I am blown away.

Before this subwoofer, I had an underwhelming subwoofer that did not go below 35hz and its RMS was 120 watts. Movie scenes with a decent amount of bass or video games or music, Just sounded like it was missing something.

Now I feel and hear the bass way more. My couch that is a couple feet away in a medium-large room shakes a bit. It truly changes the entire experience. I highly recommend. I am very happy with my purchase.
