Listening room: Rockport Technologies’ main listening room is approximately 30’6"L x 22’9"W x 11’H. Thirty-eight RPG Binary Amplitude Diffsorbor (BAD) panels are mounted on angled soffits, along with integral, tuneable, custom-made quarter-wave bass traps. The wall construction is a triple-layered, constrained-mode-damped sheathing system built on a stud-grid matrix power-nailed to 10"-thick, steel-reinforced concrete walls that themselves sit on 36"-wide, 6’-deep footings.
