FLAT PANEL SYSTEM
Perdue Acoustics’ patented Rockwool core standard Original Fabric Panels are the industry leaders in the area of sound absorption with an NRC of 1.40 for the 2” panels. The Original Fabric Panels provide an aesthetically pleasing product with high quality noise reduction and are available in standard sizes from 2’ x 2’ to 4’ x 8’ with custom sizes available.

Using the same Rockwool core as the Original Fabric Panels, Perdue Acoustics’ Original Fabric Baffles provide excellent sound absorption in the upper ceiling area, fitting perfectly between high ceiling beams or joists. The Original Fabric Baffles have twice the surface absorption area, offering the high performance absorption coefficients in standard sizes from 4’ x 2’ to 4’ x 8’ with custom sizes available.

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.

The patented MegaWedge™ and EconoMegaWedge™ Diffsorbers are designed to provide even more low frequency absorption than the Wedge™ and EconoWedge™. With the same pleasing appearance as the Original Fabric Panels, the MegaWedge™ and EconoMegaWedge™ offer a 358% increase in low frequency (125 Hz) absorption over the standard 2” Original Fabric panel and 184% increase in low frequency (125 Hz) absorption over the Wedge™ and EconoWedge™.
MegaWedge™ and EconoMegaWedge™ Diffsorbers
The Wedge™ and MegaWedge™ Diffusers are custom molded using high-impact styrene construction and specially designed diffusion “wells” with varying depths to diffuse echo across the frequency band. Available in the standard size of 2’ x 4’, the Wedge™ and MegaWedge™ Diffusers can also use the same attractive fabric options as the Wedge™ Diffsorbers.

180° SYSTEM
Perdue Acoustics’ unique 180° Diffsorbers have a 503% increase in low frequency (125 Hz) absorption over the standard 2” Original Fabric Panels. In standard sizes of 18” x 36” and 28” x 36” with custom sizes available and the same visually appealing fabric options of the Original Fabric Panels, the 180° Diffsorbers easily fit in to the décor of any facility.

STANDARD 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.

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.
Barrel Diffusers
Perdue Acoustics’ Bowed Diffusers are vacuum molded of high-impact styrene and are used to reflect or diffuse sound. The Bowed Diffusers can either be ceiling or wall mounted and fabric covered or painted.

PANEL CONSTRUCTIONPerdue Acoustics’ Diffsorbers, panels, and baffles start with our patented mineral wool core. The front and back are then covered with a random strand fiberglass mat and fabric wrapped. All product cores have a melting point of 1850° F (ASTM E-136), flame spread of 0, smoke developed rating of 0, tensile strength minimum of 2631 lbs./sq. ft. breaking load, compressive resistance of 480 lbs./sq. ft. at 10% compression, and horizontal sag of not more than 1/2” in 4 ft.
Panels can be fabricated with our regular edge finish or PVC trimmed edge treatment in a square, radius, or beveled edge. Our baffles are fully fabric wrapped and finished with a flap and grommets at the top edge for hanging.
FINISHES - We offer a large assortment of fabrics with many colors and patterns from quality industry textile manufacturers. Web Core micro-perforated vinyl selections are also available to match your facility decor.
