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

Mind blowing!

Watching a movie with this as one of my 4 subs is nothing short of life altering. This sub is worth at least twice what I paid. I love this company.

Outstanding Sub

The 12s replaced a Rel HT 1205 and the difference is night and day. Powerful clean bass, my home theater has never sounded or felt better.

Speedwoofer 12S

Amazing Quality, great price!

Purchased for my audiophile husband. He was not disappointed. Craftsmanship and sound quality are outstanding!

Holy hell

To be fair, I've never listened to a "proper" home theater setup before. All I knew was that every time I went to an IMAX showing or Dolby Vision I was mostly jealous of the sound. Its kind of silly that I have this sub and I'm quite happy pairing it with an $80 LED projector. I got some Paradigm 7SE speakers and I'm using a cheap Lepai 20W amp but honestly I prefer this sound to a proper atmos setup at a theater. I'm sure a good home setup will still blow me away, but as it is I feel like this sub will suite me for the rest of its/my life. I listen to a lot of basshead music and this thing will go low, and tests the limits of my house. It can be inaudible and make the lightbulbs vibrate in their housing. The extra features are super nice to have too and saved me some other hassle. Namely giving me a line level input/output with both a high and low pass filter. Along with a nice remote, and IR receiver input (mines behind my couch so it was necessary) Its heavy. Its big. But its built well and sounds like a dream. The racing scene in Ready Player One feels like your in a car with a crazy engine the way it rumbles my couch. I'm so happy I bought this.
