NOTE FROM RSL TEAM

Note from RSL Team

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

UNBOXING YOUR SPEEDWOOFER12S

My neighbors hate me

They arrived and immediately played Oppenheimer on 4K UHD. My wife run down the stairs in panic, heard the subwoofer, sat down on the couch and said: "I guess we don't need to go to the movies anymore"
10/10 might get a second one soon.

Heart thumping Base!!!!

I bought this subwoofer for my new media room. Its is performing great and making my overall audio experience great.

This Basshead Loves the Speedwoofer 12S

I am an old school Basshead who left the competitive car audio scene years ago. To satisfy my need for bass, I have used a competitor's 10" home sub for the past few years...and I loved it! This Christmas, I decided to splurge for the Speedwoofer 12S based on internet reviews. Boy oh boy, what an upgrade! It's still breaking in, but the increased power and depth of the bass is immediately noticeable. Yeah, I am truly glad to be a member of the RSL family. And now to fire up my Techmaster PEB, Bass 305, DJ Magic Mike, and Dynamix II CD's!

Awesome Speakers and Supreme Subwoofer

Really enjoying the 12s speedwoofer and the whole 5.1 set that I purchased from RSL. It’s truly bass that you can feel in your chest and great clarity on the 5.1 set. Not only are the speakers amazing but the customer service is top notch and responsive! Incredible packaging of the speakers during the shipping process (which was free by the way) gave me the confidence the speakers arrived unharmed.

Couldn’t be happier with my purchase for the price. RSL makes speakers that are affordable and perform exceptionally well. Would certainly buy from this company again and look forward to seeing what they come up with next.

Five Stars!

Great construction, superbly sounding deep BASS, excellent performance across all genres of Movies and Music. The enveloping SUB-BASS sound waves can and will rattle windows, glass cabinets and anything else in your home that’s not FIRMLY nailed down, including the contents of your cranium and thoracic cavity! Buy this sub without fear or trepidation!
