AVAA C2225
The Active Bass Trap for high-SPL environment.
Designed for home cinemas, clubs and small venues, the AVAA C225 extends PSI Audio’s Active Velocity Acoustic Absorber technology to larger spaces and higher sound pressure levels. Operating from 12 Hz to 130 Hz and capable of handling up to 135 dB SPL, it delivers effective low-frequency absorption where conventional acoustic treatment becomes impractical.
Built for powerful low frequencies
When bass reaches cinema or live sound levels, controlling room modes becomes increasingly difficult. Massive passive bass traps consume valuable space yet often struggle to absorb the lowest frequencies.
The AVAA C225 actively absorbs low-frequency energy without requiring large amounts of porous material. Instead of correcting the signal electronically, it treats the acoustics of the room itself, reducing standing waves, shortening bass decay and improving clarity throughout the listening area.
Whether it’s the impact of a movie soundtrack, the energy of a nightclub or the punch of a live performance, the AVAA C225 helps keep low frequencies controlled, precise and enjoyable.



The most powerful way to control low-frequency Room Modes.
The AVAA C225 is a high-performance active bass absorber for home cinemas, clubs, and small venues where low-frequency energy reaches extreme levels.
It is not a phase-cancellation device.
Operating from 12 Hz to 130 Hz, it is a pressure-based absorber that directly reduces room mode build-up and shortens low-frequency decay—even at very high sound pressure levels up to 135 dB.
- Pressure-based absorption
The AVAA is pressure based absorber.Whether you have 1 or multiple disturbing room modes, the AVAA C214 will absorb all of these and reduce the resonance time.
- Multiple room modes, one solution
Whether dealing with a single dominant mode or complex low-frequency build-up, the AVAA C225 reduces resonance time across the entire operating range.
The result is tighter, more controlled and more consistent bass in every listening position.
- No calibration required
Place the AVAA C225 where low-frequency pressure accumulates. It begins working immediately.
- No measurement.
- No tuning.

Which AVAA should I choose?
AVAA C225 or AVAA C214?
Both the AVAA C214 and the AVAA C225 use PSI Audio’s Active Velocity Acoustic Absorber technology to reduce low-frequency room modes without affecting the audio signal.
The right choice depends on your room, your sound pressure levels and your application.
Choose the AVAA C214 if…
- You work in a recording, mixing or mastering environment.
- Your priority is accurate monitoring and bass translation.
- You need precise acoustic control in a critical listening room.
- Your playback levels are typical of professional studios or home listening.
Choose the AVAA C225 if…
- Your system produces very high bass levels.
- You have a dedicated home cinema with powerful subwoofers.
- You operate a club, bar or small venue.
- You need effective low-frequency absorption at sound pressure levels of up to 135 dB SPL.

TRUST BY LEADING REVIEWERS

“Listening to a wide variety of music, with special emphasis on bass test tracks, I again felt the AVAAs C214 made an immediately noticeable difference. The more important point was that the difference was always an improvement. With the AVAAs, bass was better balanced and more natural.”
Tom Martin

“These really work!
When I switched in the AVAA traps, space expanded in all dimensions. The crowd was still raucous, but now it was mostly behind me and to my sides. The performers, still up front, were now spread wider than my room, and their individual contributions (voices, guitar, drums) were distinct and full. Finally, I was able to experience the electricity of this event fully and appreciate Seigén Ono’s reputation.”

“Making low frequency mix decisions is often one of the most difficult aspects of music production, and quite often that’s down to the effect of room modes. The AVAA C214 is a technologically advanced, easy to use and brilliantly effective product that provides a neat solution to a genuine need, and in those terms it’s a triumph for PSI Audio.”
