Product Description

AlphaSorb® Max Wedge Foam provides maximum absorption and is ideal for testing rooms, research facilities and anechoic chambers. Max Wedge Foam can dramatically improve the accuracy of sound measurements by eliminating bounce-back sounds such as echo, feedback and resonance. The deep wedge pattern offers maximum absorption and increased mid to low frequency response.

The bold, geometric design of this 3-point wedge may be applied in a variety of patterns to create visual interest and maximize the acoustical performance. Lightweight and easy to install, the anechoic wedges are the perfect solution to your demanding sound absorption applications. AlphaSorb® Max Wedge Foams may be manufactured in custom sizes to specification for testing chambers. Please contact us with your project requirements.
