This is the latest system I've assembled. It has several absolute state of the art products and is playing in a prepared room. The space is 13 feet wide 21 feet long with a 9 foot ceiling. The walls are double suspended dry wall with acoustical batting. We have beams rinning across the ceiling in two locations to aid in breakup of standing waves and the rear of the speaker area is designed as a bass trap to isolate the lowest frequency rumble associated with high spl. The woofer system s computer controlled and room corrected.
