I bought a SB3000 and a Rythmik F12G to see if I could get the performance I wanted from my mains (strictly 2 channel). I liked the SVS because it had an app that made it easy to adjust with my iphone or ipad. The Rythmik ended up being the better sounding sub in a blind test. It just seemed quicker and less like a separate part of the system. In the end I upgraded my mains and am very satisfied...for now ;)
FWIW I owned a Rel S/3 and would vote it 3rd place. I think the cheaper Rel's are the Bose of subs. They market themselves as unique but they are not.
