Product Description

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″x12″ 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.
