I am doing a whole new theater. The room is 16' x 23' with a 8' ceiling. I am thinking about the following system. The use will be 50% TV, 40% movies, 10% music. Mitsubishi 53411 TV Denon 1803 receiver 4 M&K K-5 speakers($300 per pair) 1 M&K k-7 for the center($200) Denon DVM 1805 DVD player After reading the posts on this forum, I am thinking about an SVS subwoofer. My impression is that 20-39 makes the most sense. However, do I go powered or unpowered? Also, as I know very little about speakers, I would appreciate any other suggestions as to alternatives. The 5 M&K speakers will total about $800 and I would like to stay close to that amount. I am planning to buy at ABT in Chicago because of their outstanding customer is always right attitude on everything they sell. They also carry JBL, Canton, Infinity, JMLab, and Mirage. Any suggestions would be aprreciated, thanks in advance.
