I'm only into stereo CD's at this point. I have a H/K 3370 stereo receiver and Mirage Frx-7 speakers. The speakers are great and actually have decent bass. But I'm gettin' real curious about the sub woofer experience. How bout some suggestions in the $500. and under price range. Also, while thinking about where I would put a sub in my little living room, I want to ask, is it really true that it doesn't really matter where you place the sub at in the room? If you put it off in a corner, wouldn't it make the bass guitar and bass drum seem like it was no longer centered like it's supposed to be?
