The 4" Studiofoam Wedge-22 acoustic panel from Auralex is recommended for medium to large areas like concert halls, gymnasiums and churches, rooms with pronounced low frequency problems, or where sonic accuracy is mandatory and maximum acoustic absorption is required.
The panel provides 3x the low-end control of the 2" Studiofoam Wedge-22 and can effectively tame even the worst sonic anomalies. In some instances, using 4" acoustic Studiofoam can lessen the need for significant dedicated bass trapping.
