I am currently building a home theater room in my house. So far I have purchased a Yamaha 667 receiver, Polk Tsi400's for L and R channels, Polk CS10 center channel, and Tsi100's for surrounds. I also bought an Epson 8350 projector and built and 120" fixed screen. I need some suggestions for a good sub. My room is 16' x 16'. I'm not wanting to really spend a lot of money because my wife is going to have a stroke if I keep on spending. I would like to stay around $200 if at all possible. Absolutely no more than $350. I would really appreciate any suggestions! Thanks!
