I think that my house has too much interference for the wireless audio signal to work right... I will say that my "dream" system has four EP600 subs in it. Of course, my "dream" system is an Epic 80 - 600 7.4 with an extra VP150 center so I would have a VP150 above and one below the screen... Sure, that would cost me about $12,700 for the VaSSallo series, but boy would it be nice.

Oh, and the four subs would be fun to be loud, with those subs you should be able to get great low frequency response even at lower volumes....
