Hello, I an building a new house and I want to have a complete 5.1 system for my great room. So far i have purchased the Denon AVR2805. I have 4 Acoustic Research tower speakers. I want a complete home theatre speaker system including a quality sub. My budget is $500. I like the Hsu and SVS subs. My room is 23.4 x 18.2. Any of you HT gurus can please point me in the right direction on speakers. Thank you ps I ma not going to be using the AR towers, I will sell them or put them in garage with a Sony rec.
