I have the JL Audio 110's, never had any problems. I now use it for 100% music, and they sound great. When I did surround sound, they sounded fine also. I really appreciate the DSP, it really made setting it up and matching it to the main speakers easy. I get great low bass, but it all sounds as if it's coming from my main speakers. The only thing I'd like is to be able to adjust the volume from an app. But then I'd probably be playing with it all the time, so it's fine.
I've heard good things about SVS and Rel, I doubt you'd go wrong with any of them.
