Overview
Prime7™ is a computer-optimized 1-D diffuser design utilizing quadratic residue diffuser number theory and periodic reflection phase grate principles in a highly finished acoustical product that can be mounted to most architectural surfaces. These products are precisely engineered and manufactured to provide one-dimensional broadband diffusion and wide-range scattering of acoustical sound energy without resonance, high-Q reflections, or unwanted absorption. Prime7™ are meticulously constructed to dampen unwanted resonances and resist impact and damage. It comes standard with a matte white painted finish, which provides excellent light reflectivity. Custom color options and optional fabric facings are also available.
