Hi everyone. I'm setting up a theater in my fiance's basement. I've got a yamaha htr5990 receiver and a toshiba 62MH195 rear projection tv. My question is what would be the best speaker group to use for a 5.1 system? The basement is oddly shaped, and the walls are 13.5 feet apart. I'm looking to keep the speaker cost under $3,000. Ideas? Thanks!
