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

Great Subwoofer

Great sub. Definitely has that wow this is loud factor. My living room is 18 wide and 28 deep and this easily fills the room with bass. This Thing is Huge. My tv is 75" for reference. And yes I did paint my speakers orange. I have a seating area in my bedroom that I have the mkii and its overkill for it. You really cant go wrong with any RSL subwoofer.

Good Purchase

Your delivery service was GREAT.
And the subwoofer is also GREAT.
I am VERY Pleased with my purchase.
I will probably be purchasing more subwoofers from you in the future.
Again Thanks for the GREAT service.

These guys rock!

I have had my original set of RSL speakers for over 12 years and they still sound fantastic. I wanted to update my system to ATMOS so purchased 4 height speakers and two additional subwoofers, and they all sound excellent. Shipping and product delivery are top notch and RSL is always available to help when you have questions. I dont' think you can beat the value as many of the subwoofers and speakers I looked at cost a lot more and in my opinion RSL speakers sound fantastic.

Spots on top of the speaker

I thought at first I got a used item because of the 2 spots on top of the speaker cabinet. You would not notice it till you look up close but everything else look clean except for those spots. My living room is open to the breakfast table in the back and to the left is the kitchen. I sit about roughly 23 to 24 feet from the subwoofer and I do feel my couch rattle if I crank the volume all the way up. I'm using and old 2003 Oknyo str 600 and still holding up. I am not an audiophile per say, I just liked what I like. I don't know if I need another 12s just to feel it. All in all i'm pretty happy with the subwoofer except for the spots.

Super satisfied

The 12s replaced a cheap Lancaster subwoofer. I now hear (and feel) sounds that I didn’t know was there in movies. I highly recommend this product.
