Designed to be used in situations where low-frequency issues are a problem, SONEX Super Wedges are most often found in anechoic test chambers. These 12" x 12" wedges are 6 inches thick and feature an exaggerated, yet symmetrical, anechoic wedge pattern. SONEX Super Wedges can dramatically improve the accuracy of sound measurements by eliminating bounce-back sounds such as echo, feedback and resonances.
This product is available in both polyurethane and a Willtec® brand, melamine-resin foam. Click here for important information regarding these 2 materials.
