The QuadraPyramid presents a low profile with four pyramids creating sixteen angles of reflection on the surface of a single 2’ X 2’ panel. The unit is designed for wall or ceiling grid.
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)
