I'm in the process of fully upgrading my home theater. I'm in search of great front and surround speakers. My theater is about 12 x 16 and 10 foot ceiling with two rolls of seating. I'm planning of mounting the speakers on the walls about 8 feet high in front and back Current system Denon 4300 ( New ) Klipsch Quintet speakers ( need to upgrade ) SVS PB1000 SUB ( New ) I was looking at the Polk S20 at Best Buy at 299 a pair. I listened to then a bit at the store but it's hard to read in that noisy environment. I'm on a tight budget, in search for the best bang for the buck. Thanks for your help.
