Any feedback on Rythmik Audio Subwoofers?

This is a fantastic sub. I use one with the GR Research driver, and it is much tighter and faster than the $4000 velodyne dd15 that it replaced.

I own the 12" version and love it. I have a dual system, Audio & Theatre. I plan on buying a few more. I want to setup a stereo sub configuration as well as a couple extra for the theatre system.

I just Bought a Rythmik Audio Sub's. I bought 2 15" subs. I built 4cu. foot boxes to put them in. So far I am very pleased with the results. I would do it again if I had to. It's amazing to hear the difference. I have not found the words to describe what I hear, but it seems to be music and not noise.

I bought one of their 12" sub a month ago. I'm very happy with it since I can hear very well some clean, focussed and tight bass from the lower frequences under 60.40.20.14 with no problem. Something I've been missing for so long. The 15 month old Velodyne sub had to go(sold out). I can't believe the difference this sub makes in my B&W 800 system.
PRICELESS! PRICELES!
This new guy packs up enough punch to knock out any competitor, no matter the price range.
And you can always return it within a month if you dare not liking it.

I purchased one of Tyler Acoustics DS12 subs; this using the Rhythmic A370-PEQ DirecServo amp and one of their drivers. I'd echo the comments from others above, as this sub is extraordinary not just for the price but compared to other quality subwoofers. Plenty of drive but very well controlled . . . . capable of very focused sound. In combo with Ty's D3M monitors it is a standout speaker system.

In my 30 x 40 x 12 high listening room, the single sub works just fine. So much so that my initial thought of having two subs is still that . . . a thought, with still no compelling reason to purchase the second.
