Overview

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.

Pros & Cons

👍 Pros

  • High-density, open-celled foam provides effective absorption of mid and high frequency reflections.
  • 12-pack covers 48 square feet, enough to treat key reflection points in a small to mid-size room.
  • Durable construction resists deterioration and crumbling over the life of the panels.
  • Wedge profile increases surface area for improved sound absorption compared to flat foam.
  • Partially soy-based formulation reduces reliance on petroleum-derived chemicals.

👎 Cons

  • 2-inch thickness offers limited absorption of low frequencies below approximately 250Hz.
  • Purple color may not suit every room aesthetic, and the foam cannot be painted without affecting performance.
  • Adhesive mounting can damage walls and makes repositioning difficult.
  • Does not include mounting adhesive or hardware—installation materials must be purchased separately.

Frequently Asked Questions

This pack contains 12 panels, each measuring 2 feet by 2 feet, providing a total of 48 square feet of acoustic coverage.
The 2-inch thickness is designed primarily to absorb mid and high frequency reflections. For significant low-frequency absorption, thicker panels or bass traps would be needed as a complement.
Auralex recommends using their Tubetak adhesive or similar acoustical adhesive for permanent installation. Temporary options include impaling clips or T-pins, which allow removal without wall damage.
No, Auralex Studiofoam is engineered to resist deterioration and will not crumble apart over time, unlike lower-quality acoustic foams that can degrade and shed particles.
Yes, Auralex partially formulates this foam with soy-based components to reduce petroleum-based chemical usage in the manufacturing process.
