Perdue Acoustics patented Wedge™ and EconoWedge™ Diffsorbers provide the same aesthetically
pleasing appearance of the Original Fabric Panels but offer a 61% increase in low frequency (125
Hz) absorption and a 14% overall NRC increase over our standard 2” Original Fabric Panel. The
Wedge™ and EconoWedge™ Diffsorbers are designed to minimize not only the bothersome high
frequencies, but also the “boomy” low frequencies that cause the most hearing damage.

STANDARD DIFFUSERS
Pyramidal Diffusers
Perdue Acoustics’ Pyramidal Diffusers are custom engineered and vacuum molded of high-impact
styrene. The Pyramidal Diffusers diffuse and help diaphragm low frequencies. These Diffusers can
be ceiling or wall mounted and fabric covered or painted.

Barrel Diffusers
Made from the same high-impact styrene as the Pyramidal Diffusers, Perdue Acoustics’ Barrel
Diffusers have a slightly curved face that diffuses sound and stops echoes while preserving
reverberation. The Barrel Diffusers absorb low frequencies, creating a better balance between high
and low frequency sounds. The Barrel Diffuser can be wall mounted, laid in a standard ceiling grid,
or hung from the ceiling as a “cloud” and can also be fabric covered or painted.
