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.

Budget Bad Ass!

Title says it all. Love these subs especially with all of the different input connection options. I can use in 3 different systems utilizing these. Keep it up RSL!

Such an incredible subwoofer.

After all the research, countless reviews, videos, etc ... I decided to purchase the 10S MKii subwoofer. Like some, I had my doubts that a subwoofer this cheap and small could perform as they said it would. I'm coming from subwoofers from 3 other companies, and with a price tag of $799 (10-inch price). I needed a more musical sub, with the ability to go low for movies, and of course the RSL certainly fits that bill. When I first connected it, and ran my room correction, I was not thrilled with what I was hearing. I called RSL and spoke to a very nice man who stayed on the phone with me until all my questions were answered. I let the sub burn in for some time, (not knowing I needed to do this for a sub) and now I am among the convinced. I've got this in a 2.1 stereo system, with stand mount speakers as mains, and I am complete musical heaven. As others have said, I now hear the bass - not just feel it. Bass just never sounded go good. What an amazing speaker, and an equally amazing company. Just a fantastic deal to have one of these - and I imagine I will not ever be buying another one from another company again.

I recently had the pleasure of purchasing the Speedwoofer 10s MKII from RSL Speakers and, I have to say, I am thoroughly impressed. The 10s MKII delivers a deep, powerful punch while also filling the room with smooth, low-frequency bass. Sound is clear and controlled. The enclosure is capable of reproducing a wide range of frequencies from 90Hz to just below 25Hz. Most impressive. As expected, the subwoofer is easy to set up and intuitive to use. I would definitely recommend the Speedwoofer 10s MKII to anyone looking for an affordable, high-quality subwoofer solution. Great job RSL!

Much has already been said about the incredible build quality and performance of this subwoofer, especially at its price point. The feeling that I get when I sit down on the weekend after a hard week at work, knowing that I didn't have to compromise my kid's college fund to own such a nice product, is almost as enjoyable as the product itself. High pride of ownership, zero post purchase remorse. There is a very small handful of companies that still operate like this and the ones that do, have my loyalty. Thanks RSL!

I purchased two MKIIs to fill out a ~5,500 cubic space and the result has been terrific. A lot of fun and a far superior listening experience. I imagine that like many people I am not super deep on sub specs and came to RSL via a combo of great reviews and price point. I do know a lot about customer service, however, and theirs is top-notch. Quick and in-depth responses to my questions, quite a bit of patience and help as I had to reset my order a couple of times, and a general friendliness to the whole process. All in very happy and would recommend.
