Hi all I am new to this forum and have done a good amount of research but I cannot find a direct answer to my question. I just ordered a set of Polk 75t's. I hope they are good speakers. I currently have a Harmon Kardon Avr 146 that I have barely used and a Sony SA-WM500 sub. I am trying to set up a good 2.1 or maybe 3.1 surround mostly for watching movies and TV. Will my HK 146 be enough power and give me a good realistic surround sound ? What do you gurus think of my setup for a newbie?
