## Features

- Purpose-Built for Trihedral Ceiling Corners – Designed for the three-surface junction where two walls meet the ceiling, placing deep porous foam at a common low-frequency buildup point.
- 16.5 in Face, 12 in Depth – Each pyramid-shaped trap uses deep open-cell polyurethane foam to provide substantially more porous treatment depth than standard acoustic wall panels.
- Cleaner Low-End Monitoring – Helps reduce boomy, muddy corner buildup so bass notes, kick drums and speaker playback are easier to evaluate during recording, mixing and critical listening.
- 4-Pack Upper-Corner Coverage – Treat up to four ceiling corners while preserving usable floor space and keeping vertical wall corners available for stackable Delta Bass Traps.
- Complete Room Treatment System – Pair with acoustic foam panels at reflection points and Delta Bass Traps in vertical corners; ideal for studios, podcast rooms, rehearsal spaces and home theaters.

## Questions & Answers

**Q: What’s the best way to mount them to the wall?**
A: 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.

**Q: Do I have to install them in the ceiling corners?**
A: 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.

**Q: How can I tell if they’re working properly?**
A: 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.

**Q: My products arrived slightly deformed. How can I restore their shape?**
A: 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.

**Q: The products have a strong smell when first opened. Are they safe?**
A: 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.
