WEDGE™ Series

I

The EconoWedge™ Diffsorbers** work well in traditional sanctuaries, video conference rooms, cafeterias, and gymnasiums.

Unmatched Class A fire protection as a complete panel assembly.

Ideal architectural angles that create intelligibility and understanding.

To create the desired listening experience in your room it is important to address sound diffusion to eliminate echo as well as noise reduction to negate reverberation. Perdue Acoustics’ patented Wedge™ Series Diffsorbers slope across the width of each panel and are modeled after the ideal architectural angles that create intelligibility and understanding in listening environments. Perdue Acoustics’ patented Wedge™ Series Diffsorbers are designed to minimize the bothersome high frequencies, as well as the “boomy” low frequencies that cause the most hearing damage. Because the patented Wedge™ Series creates a unique blend of absorption and diffusion, has the highest NRC range of 1.20 to 2.20, and can be covered in a variety of fabric choices to accent your facility’s décor, it is the perfect specialized solution to create your desired communication atmosphere.

Wedge™ and EconoWedge™ Diffsorbers

Perdue Acoustics patented Wedge™ and EconoWedge™ Diffsorbers provide the same aesthetically pleasing appearance of a Flat Panel but offer a 61% increase in low frequency (125 Hz) absorption and a 14% overall NRC increase over our standard 2” Flat 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.

MegaWedge™ and EconoMegaWedge™ Diffsorbers

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 Flat Panels, the MegaWedge™ and EconoMegaWedge™ offer a 358º increase in low frequency (125 Hz) absorption over the standard 2” Flat Panel and 184%increase in low frequency (125 Hz) absorption over the Wedge™ and EconoWedge™.

MaxWedge™ and EconoMaxWedge™ Diffsorbers

Sloping from 1” to 7” across the width of the panel, the MaxWedge™ and EconoMaxWedge™ Diffsorbers are designed to provide additional absorption on the upper ceiling and walls and work well as a bass trap. MaxWedge™ and EconoMaxWedge™ Diffsorbers offer a 341% increase in low frequency (125 Hz) absorption and 110% increase in overall absorption over 2” fiberglass panels.

Wedge™ and MegaWedge™ Diffusers & Reflectors

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. The Wedge™ and MegaWedge™ Reflectors are custom molded smooth reflectors. Both are available in the standard size and can also use the same fabric options as the Wedge™ Diffsorbers, making them interchangeable, allowing custom tuning of a room without changing the look of the product.
