Small Package, Big Impact

Tri-Corner Traps are built for compact spaces. Vocal booths recording vocals and instruments. Small home studios where every inch counts. Podcast studios that need controlled low-mids while maximizing floor space. These are environments where low-frequency control from 80 Hz up happens efficiently without crowding your workspace.

Tri-Corner Traps fit directly into vertical corners, absorbing low-frequency energy where it naturally accumulates. They control the frequencies that matter most for vocals, acoustic instruments, and speech — the 80-200 Hz range where muddiness, room resonance, and unclear recordings happen. The triangular design maximizes insulation depth in the corner while keeping your room open and functional.

If you're tracking vocals, recording acoustic instruments, or working in a compact environment, Tri-Corner Traps deliver the low-end control you need while keeping your space workable.

Built for Compact Spaces

Vocal Booths

Vocal booths demand low-frequency control in tight quarters. Tri-Corner Traps absorb from 80 Hz up, controlling the lowest register of vocals and the room resonances that create muddiness and unclear recordings. They fit directly into corners without eating up floor space, keeping your booth functional while improving clarity and reducing unwanted room tone.

Small Home Studios

Small home studios need smart space decisions. Tri-Corner Traps give you low-end and low-mid control from 80 Hz up without sacrificing floor area for equipment, instruments, or movement. Whether you're tracking vocals, recording acoustic guitar, or producing beats, they improve your room's sound while keeping your space functional and open.

Podcast Studios

Podcast studios benefit from controlled low-mids and reduced room resonance. While Broadband and High-Mid Panels handle the heavy lifting for speech clarity, Tri-Corner Traps add low-frequency control without taking up floor space. The result: cleaner recordings, less rumble, and a more professional sound in compact recording environments.

What Changes in Your Room

Tri-Corner Traps give you low-end control where it matters most without sacrificing the space you need to work effectively.

Vocals become clearer

The lowest register of vocals sits cleanly in recordings without muddiness or room resonance clouding the sound.

Room resonances disappear

The boomy, hollow sound that small rooms often have gets controlled, creating a more neutral recording environment.

Instruments sound tighter

Acoustic guitars, bass, and other instruments maintain definition and clarity without low-frequency buildup.

Floor space stays open

You maintain functional room space for equipment, instruments, and movement while still controlling low frequencies.

Recording becomes easier

Less cleanup in post-production, more confidence in your recordings, and a room that supports your work instead of fighting against it.

Performance You Can Trust

We test every product at Riverbank Acoustical Laboratories, one of the most respected acoustic testing facilities in North America, following ASTM C423 standards. This ensures the performance data you see is independently verified and accurate, so when we list absorption at a specific frequency, you can trust the results.

Tri-Corner Traps are tested using corner-mount configuration, delivering effective absorption from 80 Hz up. The data shows strong performance in the 80-200 Hz range where vocals and acoustic instruments carry their fundamental energy.

All data shown is corner mounted.
X Axis = Frequency in Hz | Y Axis = NRC Rating from 0-1

NRC stands for “noise reduction coefficient.” An NRC rating is a percentage grade that represents a specific panel’s ability to reduce noise.

Ratings are typically expressed in decimals from 0 to 1, where 0 represents 0% (meaning the product reflects sound) and 1 represents 100% (meaning the product absorbs sound)

So, for example, if a panel has an NRC rating of .85, that means that roughly 85% of the sound that hits that panel’s surface will stop there

Ratings can go above 1 because they’re calculated by scoring all of the surfaces of the product, leading to ratings like 1.05.

Why Corner Treatment Works

Corners naturally accumulate low-frequency energy, making them strategic locations for acoustic treatment. Tri-Corner Traps take advantage of this by fitting directly into vertical corners where two walls meet, absorbing low-frequency energy from 80 Hz up without requiring floor space.

The triangular design allows the panel to sit flush against both walls while maximizing insulation depth in the corner itself. This creates effective absorption in the frequency range where vocals, acoustic instruments, and low-mids carry their core energy. For small rooms where floor space is at a premium, this design delivers meaningful low-frequency control without the footprint of larger corner solutions.

Tri-Corner Traps work particularly well in rooms where deep bass control below 80 Hz isn't the priority. Vocal booths, small tracking rooms, and home studios benefit from controlling the 80-200 Hz range where most recording happens, and Tri-Corner Traps handle that range efficiently while keeping your room open and functional.

Your Questions: Answered

The answer depends on your priorities: space or performance. Bass Trap Panels straddling corners deliver significantly more low-frequency absorption, extending down to 63 Hz and providing better control across the entire low-end spectrum. They're also more cost-effective. The trade-off: they require floor space. Tri-Corner Traps fit directly into corners without taking up floor area, making them ideal for vocal booths, small home studios, and compact spaces where every inch matters. If you have the floor space and need maximum low-end control, straddled Bass Traps are the better choice. If floor space is limited and you're primarily recording vocals or acoustic instruments (not mixing or mastering), Tri-Corner Traps deliver the performance you need while keeping your room functional.
Tri-Corner Traps are designed for vertical corners where two walls meet. In most small rooms, you'll want to prioritize the corners behind your listening position or recording position first, as these tend to accumulate the most low-frequency energy. For vocal booths, placing them in all four corners can provide excellent control without sacrificing usable space.
Tri-Corner Traps work well for tracking and production, but they're not ideal for critical mixing or mastering environments. For mixing and mastering, you need deeper low-frequency control than Tri-Corner Traps can provide. Bass Trap Panels (straddling corners or wall-mounted with air gaps) or SubFreQ panels are better suited for those applications.

Yes, but they're not the most common choice. Home theaters typically benefit more from Broadband or Bass Trap panels for fuller frequency control. Tri-Corner Traps can supplement a treatment plan if you need additional corner control without sacrificing floor space, but they shouldn't be the primary treatment approach for home theaters.
For vocal booths and small studios, 2-4 Tri-Corner Traps (one in each corner or in the back corners) typically provide meaningful improvement. The exact number depends on your room size and goals. We offer free room layout designs to show you exactly what your space needs and where panels should be placed for maximum impact.
An absorption coefficient measures how much sound energy a material absorbs at a specific frequency. A coefficient of 1.0 means the material absorbs 100% of sound energy that comes into contact with the acoustic treatment at that frequency, while 0.0 means it reflects everything.
We report frequencies where our panels provide meaningful absorption (absorption coefficient greater than 0.5). This ensures you know exactly where our products will make a real difference in your space. When we say Tri-Corner Traps are effective down to 80 Hz, it means the panel absorbs at least 50% of sound energy at that frequency and above.
