I used to have the JVC HX-Z3 system...460 Watts, fairly similar design w/ subs on the sides of each speaker. I loved the sound. The bass was incredible! Not bad at all for a shelf system. And those are so cheap now. I got mine 3 years ago for $400+. Now they're around $200.
My receiver doesn't work anymore but I still have the twin 8" hyper-power drive subwoofers that I want to use somewhere, somehow.
