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

rsl speedwoofer 12

this speedwoofer is amazing. enclosure and porting tuning absolutely exceeded my expectations and easily overpowers my theatre space. would definitely purchase the speedwoofer 10 to compliment the full range of sound the 12 has already accomplished. great value for the money.

Great product great service

I had trouble getting my subwoofer to work at all even though it powered on. I spent time on the phne with customer service attempting varouis fixes. I have a 1970s Marantz system and somehow after unplugging and plugging cords into variouus ports the speaker started wrorking. It was great working the customer support. The speaker has added a whole new dimension to my music.

Nice upgrade!

I had purchased a 12S to replace a pair of old Polk PSW505(s). I was quite impressed with the room filling sound this produces. With the finely adjustable phase control, i had no problems getting the 12S to blend in nicely. Many props to the sound and build quality!

Great Subwoofer

I have had this subwoofer for about a month and it is great. No complaints from me. I did experience some shipping damage but working with Joe in customer service was a pleasure. The damage was cosmetic and did not affect performance at all.

Can’t beat it for the price/performace

If you can’t deal with the larger cabinet and are in this budget range. You can’t get any better sound and quality.
