QuadraPyramid™
Sound Diffuser
|
|
 |
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).
