im going to use the extra bedroom as a hometheater And need some help, the room is approx 8x10, i was going to have 2 armchairs at the back and screen as big as possible on the other. Now what do i do about the sidewalls, backwall and front wall, i obviously can't do much as i can't modify much but what little things can help? i could nail stuff, that shouldn't be a problem. I'm usint a htpc with promedia 5.1 speakers, so i don't have great speakers but good enough for me. So any advice?
