In small rooms, interfering reflections that degrade playback quality can be controlled by absorption or diffusion. However, over-application of absorptive surfaces creates "dead" spaces. The QRD PA is a modular, reflection-phase grating panel, what RPG calls a "One Dimension Quadratic Root Diffusor" (1D QRD.)
This one dimensional diffuser produces a directional hemi-disc polar response that can be oriented in any direction. It also provides low-frequency absorption below the design bandwidth. Its wide bandwidth and low cost make it a logical choice for any project studio or home theatre.
Other applications include vocal booths, instrument and drum isolation booths, gobos, individual practice rooms, band rehearsal rooms and home listening rooms. Each panel has a "Faux Maple" finish.
