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 typically available to ship from stock. The QuadraPyramid™ Diffuser generates a uniform polar response over a broad frequency range. There is very little sound absorption when used as a ceiling mounted device in a standard grid (NRC=0.10). When wall mounted in a specific manner, it becomes a mid-bass absorber in the range of 250 Hz (0.60 SAC) with the skirt of the bell curve extending down to 125 Hz on the low end and 315 Hz at its upper limit (NRC=0.20).
