I have a room 25x25x10 W L H, it has windows on two sides, connecting hall with a large entry, wood floors for dancing. I bought everything the stereo shop guy suggested, Paridigm cinema 90's for the corners, cinema 110 LCR for the center, PDR-8 for the Sub. a Yamaha Rx v2700 reciever, and a DVD S1700 player. The system sounds great..(except out of balance) but should I calibrate with the YPOA. I can hook up a Yamaha LPX 510 for the calibration but I think I'll end up selling it for a LCD display to save the relationship. She doesn't want it hanging from the ceiling. Anyway. The center seems to be the dominate channel and I barely here the satellites. What is the best setting for music?? Would you calibrate based on the center of the room, the rear... Any suggestions would be appreciated.
