PSI Audio AVAA C20

Handmade in Switzerland

At our Swiss workshop, all our products are crafted by hand with a passionate attention to detail. Handmade manufacturing has a key advantage over industrial production – it allows us to match and adjust components so that tolerances cancel each other out, instead of building up.

Analog active bass trap

Unique: easy to set up and move, no calibration required, as efficient as passive absorbers 25 times its size, the AVAA C20 typically reduces the resonance time of all room modes between 15 Hz and 150 Hz by up to 50%. With a surface of 0.2 m2, an AVAA is as effective in absorbing low frequencies as 1.5 m2 of perfect sound absorber (such as a hole in the wall).

Key points:

– The AVAA absorbs room modes between 15 and 150 Hz
– 2 AVAAs will make a significant difference in normal sized studios
– 4 AVAAs will allow to achieve even better results in large studios
– Adequate AVAA positioning is easily achieved after a few trials
– No setting are required only ON/OFF

Working from 15Hz to 150Hz

Whether you have 1, 2, 3 or more disturbing room modes, the AVAA C20 will work on all of them. It will absorb all undesired room modes.

AVAA is a revolution

Since its release in 2016, AVAA has grown a reputation of being the secret weapon of the acoustic treatments and a revolution in room acoustics. In 2023, the active acoustic treatment is also done digitally with the AVAA C214.

What does the AVAA do?

The AVAA is a solution for room mode problems. The AVAA is designed to absorb the standing modes between 15 and 150 Hz in a room. It will do so just like passive absorbers but in a much more efficient way and using up much less space. Each operating AVAA will have the same effect as a hole in the wall much larger than the dimensions of the AVAA (that is 0.2 m2). The exact ratio will depend on the frequency and environment but typically range between 5 and 20.

The AVAA will affect the impedance of the air and suck low frequencies around it. Therefore the best position to place an AVAA is in the most rigid corners as that is where all room modes will be most present. It is important to work on the positioning of loudspeakers and listening, as the AVAA will have little effect on inevitable first reflections.

What does the AVAA not do?

The AVAA is a solution for room modes below 150 Hz and absorbs low frequencies only. It is therefore not a total solution for acoustically bad rooms. For best results, it needs to be combined with passive absorption in higher frequencies. The AVAA will only absorb pressure waves within a radius of 1 to 1.5 m around it in these frequencies. It is therefore not a solution for the first reflections a room might have. Correct positioning of speakers and listening position in the room remains necessary.

What are the advantages of the AVAA?

– It is an efficient solution for room mode problems
– It is stable with no settings required
– It can be turned ON and OFF to alter the acoustic environment
– It an easily be moved into a different room

No calibration required

Simply place it where your room modes are and it will absorb them. No calibration required.
