QRCD: Quadratic Residue Ceiling Diffusers

Quadratic Residue Ceiling Sound Diffusers are installed in ceiling grids or hung like clouds for open ceiling designs.  Based on the quadratic residue sequences of elementary number theory, QRCD diffusers use their shape to improve sound quality by disrupting standing sound waves.

Applications:

music rooms, performance halls, auditoriums or large spaces requiring ceiling sound absorption and sound scattering

Finish:

Textured White

Mounting:

Lay-in ceiling grid system

N.R.C.:

.35
