I am with Advanced Audio Video, LLC. Our web site at www.advancedaudiovideo.com
has more on how to control acoustics in a room. We do auditoriums, home theaters, etc, and have a background in acoustics. In fact, we have THX certification in our model theater. We've done large commercial theaters for Disney and others, as well as home theaters. Audio is very important, but audio is no good if the room is not properly treated. Visit our web site for more information on treating a room.
