ATS Acoustics Sound Absorbing Acoustic Panel with Sona Fabric, NRC 1.0, Fire Rated, 24 x 48 x 2 in (Pitch)
The standard 2 in mineral wool panel for first reflections and rear walls, with published third-octave absorption data and a Class A fire rating that many cheaper panels lack. Plan on four to eight for a typical room.
$90 each typical, as of October 2026

- 24 x 48 x 2 in
- Rockwool AFB mineral wool core
- NRC 1.00 (independent test)
- Class A fire rated, Guilford of Maine Sona fabric
This is the reference 2 in panel: mineral wool core, a Class A fire rating, and third-octave absorption data published by the maker. It handles first reflection points and rear walls in a home theater without the dead, over-damped sound that thicker foam can produce.
Watch out: Sold one at a time, so a typical room order is four to eight separate items.
Pros
- Independent NRC 1.00 test
- Class A fire rated
- Many Guilford of Maine fabric colors
Cons
- No multi-pack on Amazon
- Only 2 in, so not a bass trap
- ATS product photos are small
