Detail 01
2 inches thick
Absorbs mid and high frequencies well. Below roughly 250 Hz it does progressively less, so bass buildup stays.

Auralex2" Studiofoam Wedge 2'x2'x2" Panels 12-Pack - Charcoal 2"
Independent shopping perspective
The Korena take
Twelve 2x2-foot foam wedge panels, two inches thick, covering 48 square feet. For treating first reflections and flutter echo in a small room.
Strong match
Who this is for
- Treating reflection points in a home studio or vocal booth
- Taming flutter echo in a square room with bare walls
- Voiceover or podcast spaces where mid and high control matters most
Consider the trade-offs
When to look elsewhere
- Anyone chasing bass control — two inches barely touches low frequencies
- Blocking sound from leaving or entering a room
- Large rooms; 48 square feet is a partial treatment at best
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
48 square feet total coverage
Enough for reflection points on two walls plus a small ceiling cloud in a modest room.
Detail 03
2' x 2' panel size
Small squares give placement flexibility. You can spread them in a checkerboard rather than covering whole walls.
Detail 04
Wedge profile
Angled surface scatters some energy rather than reflecting it straight back, which helps with flutter between parallel walls.
Detail 05
Charcoal gray finish
Dark and neutral, so it recedes visually. Foam picks up dust over time and is hard to clean.
Final check
Know before you order
- 01Adhesive is not included — plan on Foamtak or two tubes of Tubetak
- 02Mount to a backing board if you rent and can't glue walls
- 03Spreading panels around beats clustering them all on one wall
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this soundproof my room?
No. Foam absorbs reflections inside the room. It does not block sound passing through walls, which requires mass and sealing, not absorption.
02How do I mount these without ruining my walls?
Glue foam to thin plywood or foam board, then hang that panel. The adhesive grabs foam hard and pulls paint off drywall.
03Is 48 square feet enough for my room?
For a small bedroom studio, it covers primary reflection points. Larger rooms will want a second box or additional bass treatment.
04What is the difference between the 2-inch and thicker panels?
Thickness sets how low the absorption reaches. Two inches handles mids and highs; going thicker extends control further into the low mids.
