Prime7-2D™ Natural is a two-dimensional quadratic residue diffuser that diffusers and backscatters sound uniformly from all angles of incidence. Its solid wood construction is an attractive complement to architectural design and is suitable for wall and ceiling applications. 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. 


Prime7-2D™ Natural is ideal for rooms and spaces that require an effective, lightweight, acoustical product that diffuses and back-scatters sound where noise control is a consideration. Some applications include:

Auditoriums — Performing Arts Centers — Lecture Halls — Convention Centers — Churches — Music Spaces — Recording Studios
