We recently moved into overseas military housing built of concrete blocks and designed for one purpose: to withstand typhoon force winds. With smooth, cement walls and hard, tile floors, it is an acoustical nightmare! My wife and I put moderately heavy window treatments up and carpet on about 2/3 of the floor in the 12 x 25 foot livingroom where we have our HT, but the acoustics are still terrible. The bass is mushy and the highs sound harsh. It pains me that I am not experiencing the true beauty of my Anthem/Parasound/Paradigm Reference system, but I have never had to deal with this kind of situation before. Where do I begin in analyzing and minimizing the problems inherent in this room? Thanks!
