I went all PolK Audio last year when I re did my HT system.

Polk TSi-300 towers with matching series center and surrounds.
Polk -PSW 100 sub I think it is, 200watts front facing
Klipsch- 450w Sub, down firing.
Yamaha RX-473 Receiver

Thing is I loved the Klipsch, but the horns were just too much in there sound room for my taste even after trying to eq them down. My LR is much bigger than the test room so I've always second guessed my decision. This thing sounds great and shakes the house. TV volume about-28db, TV Movie -22db, BluRay -10db.

Whats your take
