I have a HT with CS400 and 4 RT55's plus Sub. In my old HT it sounded great. Now I moved and finished the basement in the new house, built a custom HT but it sounds terrible. The ceiling is a custom coffered ceiling made by Owens Corning called Quietzone Acoustyle. Well between the partially eposed cermic tile floor, the drywalls and ceiling it is way too lively and basically sounds like crap.
Any ideas how I can get my sound back?
