Prime7-2D™ Two-Dimensional Quadratic Residue Diffuser

Overview

Prime7-2D™ is a two-dimensional quadratic residue diffuser that diffusers and backscatters sound uniformly from all angles of incidence. It comes standard with a matte white painted finish, which provides excellent light reflectivity.  Custom color options and optional fabric facings are also available. This product’s design is optimized with the use of quadratic residue number theory and computer modeling analysis, then precisely manufactured to provide desirable, two-dimensional diffusive scattering of returned acoustical sound energy.
