Auralex 4" Studiofoam Wedges are recommended for medium to large areas - like concert halls, gymnasiums and churches - as well as rooms with pronounced low-frequency problems or where sonic accuracy is mandatory and maximum absorption is required (e.g., voiceover or drum booths, forensic audio labs and mastering rooms).

Auralex 4" Studiofoam Wedges provide three times the low-end control of 2" Studiofoam Wedges and can effectively tame all but the worst sonic anomalies. In some instances, using 4" Studiofoam Wedge can lessen the need for significant dedicated bass trapping. If you desire the best absorption possible, go with Auralex 4" Studiofoam Wedges.
