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.
