Prime7™ Natural Quadratic Residue Diffuser

Overview

Prime7™ Natural 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. Its solid wood construction is an attractive complement to architectural design and brings a warm appearance to any space. 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™ Natural are meticulously constructed to dampen unwanted resonances and resist impact and damage.  

Applications

Prime7™ Natural is ideal for rooms and spaces that require diffusion to help scatter and blend the sounds in a room for the listening enjoyment of both music and speech. Some applications include Auditoriums, Performing Arts Centers, Lecture Halls, Convention Centers, Churches, Music Spaces, and Recording Studios.
