Prime7™ Mid-Range Quadratic Residue Diffuser

Overview

Prime7™ Mid-Range is a mid-frequency design for reflective phase grating diffusers that is computer-optimized utilizing quadratic residue number theory with periodic principles and an innovative well design that reduces overall thickness while increasing performance over standard designs. Prime7™ Mid-range are engineered and manufactured to provide one-dimensional (horizontal or vertical) diffusion and wide-range scattering of sound energy without resonances, high-Q reflections or excessive absorption.
