Product description
FOROOMACO Triangular Pyramid Bass Traps 4-Pack
Corner-Optimized Acoustic Design for Low-Frequency Control
Designed for Trihedral Corner
Purpose-built for three-surface junctions, its triangular form fits precisely into ceiling corners to control low-end buildup.
Foam That Serves the Sound
High-density acoustic foam engineered to absorb bass energy where it accumulates most—right at the corners.
Deeper. Cleaner. Controlled
A true 12" depth designed for meaningful low-frequency absorption—delivering smoother, more accurate room response.
Purposeful Geometry and Finish
Defined by its triangular symmetry and dark matte texture, it complements real-world studio spaces with both form and function.

My products arrived slightly deformed. How can I restore their shape?
The foam may compress during shipping.
Lightly soak the bass traps in water, squeeze out the excess, and let them air-dry completely to regain their original shape.
-
The products have a strong smell when first opened. Are they safe?
Yes. The bass traps are made from formaldehyde-free polyurethane acoustic foam and are completely safe for indoor use.
The initial odor may come from sealed packaging but will fade naturally after a day or two in a ventilated space.
-
What’s the best way to mount them to the wall?
Use Foroomaco’s Mini Ear pads for clean, secure installation.
They hold firmly without wall damage or residue.
Make sure the surface is clean and dry before applying.
-
Do I have to install them in the ceiling corners?
Bass traps are designed for three-surface corners where low frequencies naturally build up.
Installing them on flat walls greatly reduces performance.
Place them symmetrically in ceiling or floor corners for optimal sound balance.
-
How can I tell if they’re working properly?
After installation, play music or a bass-heavy track in your room.
You’ll notice that the boomy, muddy low-end becomes tighter and more controlled — a clear sign the traps are absorbing excess bass energy.
