PSI Audio AVAA C20 Graphite Black
Active Bass Absorber – The Revolution in Room Acoustics
The PSI Audio AVAA C20 is an active bass absorber designed to remove standing room modes between 15 Hz and 150 Hz, dramatically improving the acoustic quality of any room. Its efficiency equals that of a passive absorber 25 times its size, allowing superior low-frequency control even in small spaces – without any calibration or setup required.
Placement is simple: just locate your problem areas or experiment – room corners are usually a good starting point. The AVAA C20 operates fully analog, with zero latency, and does not emit sound or alter the source signal. Even two units can make a significant difference in studios up to 25 m². It works perfectly in recording, mastering, or home studio environments.

How It Works
The AVAA C20 absorbs unwanted low frequencies by sensing the acoustic pressure in the room and generating an inverse acoustic impedance. This allows it to reduce room resonances effectively – without using digital processing or affecting the sound source. The result is a tighter, more accurate bass response and improved overall clarity.
No Calibration – No Setup – Instant Results
Simply place the AVAA C20 where your room modes are most pronounced, plug it in, and let it work. It automatically adapts to your space and instantly improves the room’s low-frequency behavior. No calibration, no software, no hassle – just pure analog acoustic treatment.
AVAA – A Revolution in Acoustics
Since its release in 2016, the AVAA C20 has become known as the “secret weapon” of acoustic treatment. It set a new standard for active room correction – delivering natural, balanced bass response without digital coloration. In 2023, PSI expanded this concept with the digital AVAA C214, continuing the evolution of active acoustic control.
