POWERFUL SOUND. WITHOUT THE ROOM GETTING IN THE WAY.

Without AVAAs

With no AVAAs present in the room: measurement has been taken in a 20m2 recording studio, equipped with two large loudspeakers, with an obvious room issue occurring at 32 Hz.

With AVAAs

Having added two AVAAs into the room: a better balance is achieved in general, better stereo imaging in the low end and a 300ms reduction is put in place at 32 Hz to combat the aforementioned issue

De-rumbling the room: the AVAA principle


Room modes are one of the biggest challenges in room acoustics. Every room has them, no one wants them, but getting rid of them is very cumbersome and laborious with traditional passive acoustics. Porous absorbers take up a lot of space to be effective in low frequencies. The alternative resonant absorbers like membrane absorbers or Helmholtz absorbers can be effective at low frequencies, but generally only ever cover a very narrow band of the spectrum, to which they need to be tuned. The AVAA system, however, is effective in the entire range from 12 Hz to130 Hz, and as efficient as a porous absorber 40 times its size. No tuning required, it simply does away with the room modes and clears up the sound in the entire room

 

High-power absorption for home cinemas, clubs, and studios

PSI Audio designed the AVAA C225 for applications with lots of energy in the low frequency spectrum. Home cinemas need that intense low rumble to optimally support the pictures of high-octane action movies; clubs make people dance with that energetic thumping of electronic kicks. To fully enjoy these bass-fueled delights, they must be projected concisely, and that is where the room often interferes. Room modes prolong certain frequencies, until the kick turns into a hum with no defined edges. The AVAA C225 counters these effects of the room, taking up much less space than equally effective porous absorbers would require, and not needing tuning like resonant absorbers do. The C225’s two 10-inch membranes absorb up to 135 dB of pressure–ensuring that the boom retains its power but never loses its edge.
