Auralex 4 Inch Studiofoam Wedge 2x2 Foot Panels - Burgundy x 6 400-Series-PriceDrop Overall widthProduct Information: 4" Studiofoam Wedges are 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 (e. g. voiceover or drum booths, forensic audio labs and mastering rooms). 4" acoustic Studiofoam Wedges provide 3X the low end control of 2" and can effectively tame even the worst sonic anomalies.
