Our home theater started out as an unfinished basement room with dimensions of 14 by 18 by 9 feet. The room is rectangular, with three doors and no windows. Audio problems are inherently more difficult to solve than video problems. Fortunately, the room dimensions are friendly to acoustic resonances. Since the theater would be right under the great room of the house, the main goal was to decouple the theater from the rest of the house as best as possible.
