The QRD 1D 423 is a 1D Schroeder diffuser based on the prime number 23, designed to optimise professional listening rooms, home theatres and recording studios. Due to the large number of bays, sound waves are effectively diffused over a very wide frequency spectrum. Due to the deep shafts, even low-frequency sounds are effectively diffused.
