Acoustics First Corporation Flat Panel Diffuser HiPer Panel™ E400

The HiPer Panel™, (Flat Panel Diffuser) combines absorption and diffusion into one sound panel. This device is similar in appearance to standard fabric-covered acoustical wall panels, such as Sonora®, and can be intermixed with them.
Acoustical performance differs significantly from outward panel appearance. The patented internal structure uses two layers of absorption, separated by a barrier septum, to form a low-profile, composite absorber / diffuser product.
The layers have a pattern of wells that yield an equal distribution of absorptive and reflective regions, both vertically and horizontally. Their constructive and destructive interference with incident sound, produced by the varied hole-pattern combinations, creates significant sound scattering in the critical mid-frequencies.

The QuadraPyramid™ is a variation of the traditional offset pyramidal diffuser. It’s patented low profile design presents four pyramids to create sixteen angles of reflection on the surface of a single 2’ X 2’ panel, with each pyramidal quadrant rotated 90 degrees.

The QuadraPyramid is used to provide sound clarity and greater perceived spatial response while at the same time delivering desirable, targeted absorption at lower frequencies. The QuadraPyramid ships “nested” to reduce both freight cost and storage space. Quantities are usually available to ship from stock
