Diffusors work on the principle of modifying the location and movement of sound in the space in relation to itself and other frequencies. A proper diffusor impacts sound waves in 3 domains – time, direction, and intensity. GIK Acoustics offers well-type QRD’s (Quadratic Residue Diffusors) which modify the location of various waves in relation to the room through the use of “wells” with different depths. We also have a variety of absorption / diffusion products such as our Alpha Series, PolyFusor and optional Scatter Plate.
