currently my EP500 is part of a built in entertainment center- which affects the visceral feel of the sub, I'd like to either liberate it and use a smaller one in it's place, or add another EP500 somewhere in the back of the room. Right now I have too many little fingers that would tear it up if it was out in the open. In a perfect world I'd have an EP600 on either side of my plasma (see my sig for photos)...
