Auralex 2SF22PUR-HP Studiofoam Wedges 2x2 Purple 12-Pack

The Auralex 2SF22PUR-HP Studiofoam Wedges are a staple in acoustic treatment, designed to absorb mid and high frequency sound reflections that cause flutter echo, slap back, and an overly reverberant listening environment. Each panel measures 2 feet by 2 feet with a 2-inch wedge profile, and this 12-pack delivers 48 square feet of coverage—enough to address primary reflection points on walls and ceilings in a project studio, vocal booth, podcast room, or home theater. The wedge shape increases the effective surface area of the foam, improving absorption efficiency compared to flat panels of the same thickness.

Constructed from high-density, open-celled foam, these panels are built to last. Unlike budget acoustic foams that can yellow, crumble, and shed particles over time, Auralex's Studiofoam maintains its structural integrity and acoustic performance for years. The foam is also partially formulated with soy-based components, reflecting a commitment to reducing petroleum-based chemical usage. For installation, Auralex recommends their Tubetak adhesive for permanent mounting, though removable options like impaling clips are available for renters or temporary setups. Keep in mind that at 2 inches thick, these panels are most effective in the mid to high frequency range; rooms with significant low-end buildup will benefit from supplementing with corner-mounted bass traps.
