When it came time to build a home theater in the basement of our home (14.5 by 18.5 feet), my wife set the tone by requesting a traditional movie theater décor with a touch of whimsy. On the technical side, I was most concerned about the installation and soundproofing to ensure it sounded as terrific as it looked. The walls, stage, and seating platform are all filled with insulation, and the walls are covered with sound panels, made from 1-inch-thick batting, and covered with velvet fabric and then framed with wood trim boxes. Molding added the extra bit of elegance, and pillars gave the room dimension and function. Doubling as sound panels, two of the pillars have cabinet doors. One of them opens to reveal the equipment rack; the other has shelves for storage.
