GIK Acoustics Classic Bass Trap Panel (4 inch) vs ATS Acoustics Acoustic Panel with Sona Fabric, 24 x 48 x 2 inch
Which should you buy? Our verdict on both, pulled from our full The Best Acoustic Panels: 4 Compared (and One to Skip) comparison.
The GIK Classic Bass Trap Panel in its 4 inch depth is the pick, because depth is the single variable that separates panels that fix a room from panels that decorate it. The ATS 2 inch panel is the better value when your complaint is echo and harshness rather than boom, and it covers far more wall for the money.

GIK Acoustics Classic Bass Trap Panel (4 inch)
Buy itA genuinely deep absorber that keeps working where thin panels quit, which is the part of the spectrum wrecking most small rooms.
- At 4 inches deep it keeps absorbing down toward roughly 100 Hz, so it treats the low mids that make small rooms sound boomy
- Also sold in 6 inch and 8 inch depths, so you can go deeper in corners without switching brands or fabrics
- Absorbent core in a wood-railed frame with over 20 fabric options, so it survives the living room aesthetic test
- One panel type handles first reflection points and corners, which keeps planning and installation simple
- Costs several times what a foam multipack does, and a room still needs several panels to change
- It is bulky. Four inches plus mounting hardware is very visible on a wall in a small room
- Buying direct from the maker means shipping waits and less casual return convenience than a marketplace order

ATS Acoustics Acoustic Panel with Sona Fabric, 24 x 48 x 2 inch
Buy itThe sensible default panel: mineral wool core, Class A fire rating and enough surface area per panel to actually change a room.
- Rated NRC 1.0 with a mineral wool core, so it works across speech and music mids and highs rather than only the top octaves
- Fire rated Class A per ASTM E84, which matters when you are covering large wall areas or treating a rented or commercial space
- Wood internal frame and woven Sona fabric hold their shape and edges far better than bare foam
- The 2 by 4 foot format means fewer panels, fewer holes and a faster install than tile-sized products
- At 2 inches its absorption tapers off below roughly 250 Hz, so it thins echo and harshness without fixing genuine bass problems
- Air-gapping it off the wall improves the low end, but the supplied hardware assumes a flush mount
- This 2 by 4 foot panel is 2 inches thick (the 4 inch version is a separate, pricier panel), so corners and deep bass still need a thicker solution
