Quadratic Residue Diffusor

We are proud to offer our own Quadratic Residue Diffusor at an incredibly affordable price. Exceptionally effective and versatile acoustic tool, it provides low mid-range diffusion and absorption. Today, we are using less bass traps, allowing the bass to develop as best it can.

In small rooms as low frequency is modulated to higher notes, (200 – 500 Hz) the QRD diffuses and lowers this energy helping to smooth frequency response and lower low mid-range reverberation.

Additionally, a fabric wrapped fiberglass absorptive panel can be mounted on the face or back to provide greater and/or variable frequency absorption.

Available in the following:
Size: 24” x 48” x 9.5”
Material: Particle Board
Finish: Unfinished
