My home theater is fairly modest, sony str-dh590, with cerwin vega slx28 left and right with the matching center channel and klipsch 5 inch bookshelf speakers in the rear. That said we were satisfied with the system for over a year.

Then I decided I wanted a subwoofer and was convinced I really wanted the 12 inch or possibly a 15 inch. But after tons of research I was more convinced I wanted the 12 inch. I contacted rsl via email and explained what I wanted, and it's intended use as well as my space that I have. They suggested since my living room was rather small to get the 10 inch. I reluctantly agreed.

I set it up with very minor adjustments though the 1st movie (volume adjustments) and let me tell you it the movie (mad max fury road) came alive. We had watched several movies since that we watched before we received the subwoofer, and we are in awe at the difference it actually made.

I might consider getting a second in a few months and place my towers on top of each one. But honestly fear it might be to much for the house to withstand.

I would definitely recommend this especially at this price point. Absolutely amazing.

The Speedwoofer performs well alongside my Bower & Wilkins 606 S3's. Pleasently provides the bottom end that's needed to accomplish a fulfilling listening experience. (Highly Recommended)

Great sub for listening to music and not half bad with movies as well.

I live in a country with poor sub availability. RSL helped me understand what I'd get, how it would perform differently on my local electric grid, and shipped at a super competitive price.

Honestly, when I buy another sub, this is where I'm coming. It has been a much needed addition to my soundscape.

I have a large space to fill. I just returned a competitor's sub, as it seemed like no upgrade from my old 8" sub. I had a long chat with a member of the support team and decided to pull the trigger on the 10S MKII. I made the right decision! The 10S produces clear, crisp bass that adds much-needed extra depth to the sound. One thing in particular impressed me - the amount of natural, added bass to low-volume listening. I've also been wowed by the sub's performance when using my system for movie soundtracks. And of course, playing music 'loud' is quite the cool experience. Finally, I don't need to be sitting in my living room sweet spot to hear the benefits of the 10S. In summary, I could not be more pleased with what the 10S has added to my system sound.
