YOUR ROOM. YOUR SOUND.

WHEN BASS LINGERS,
DETAIL DISAPPEARS.

You chose your system for what it can reveal. Room resonances can get in the way, prolonging some bass notes and obscuring the next.

AVAA absorbs low-frequency energy in the room, helping those resonances fade faster. So you can listen with greater clarity.

MEET AVAA C214

SMALL FOOTPRINT.
A CLEARER PICTURE.

For the studio where every decision matters.
For the listening room where music comes first.

A slim aluminium enclosure, black or white finishes and optional mounting feet make the C214 easy to integrate into your space. Use the app to switch individual units or groups on and off, and adjust sensitivity.

AVAA IN PRACTICE

LESS RESONANCE.
MORE ROOM FOR MUSIC.

In the published example below, a 20 m² studio had a strong resonance at 32 Hz. Adding two AVAA units reduced decay time at that frequency by 300 ms.

THE AVAA PRINCIPLE

SENSE. PROCESS. ABSORB.

Active absorption acts on the sound energy in your room.
No connection to your audio signal chain is required.

01

SENSE

A sensor monitors acoustic pressure around the absorber.

02

PROCESS

The active control system responds continuously to the pressure it senses.

03

ABSORB

The absorber draws low-frequency energy out of the room, reducing resonant decay.

A FEW PRACTICAL DETAILS

YOUR ROOM.
YOUR QUESTIONS.

Which AVAA should I choose?

Start by exploring the C214 for studios and hi-fi listening. The C225 is designed for higher sound pressure levels, including high-performance home cinema. Your dealer can help match the model to your room and listening levels.

How many units do I need?

The number depends on your room, the resonances you want to reduce and your listening requirements. A dealer can help you plan placement and assess whether additional units would be useful.

Where should I place them?

AVAA works at locations with high low-frequency acoustic pressure, often near room corners. Placement affects the result, so consult the product manual and try suitable locations in your room.

Will AVAA work with my speakers?

Yes. AVAA treats the room independently of your loudspeakers and electronics. It does not need to connect to your audio signal chain.

Does it require calibration?

No calibration is required. The C214 app offers optional sensitivity adjustment and control of individual units or groups.
