The ultimate weapon on the bass front
tdd587, 18.04.2018
The AVAA is basically a pressure cancelling device working in the lower frequency domain. All you have to do is to find a good spot where the pressure is maximized, turn it on and you are done. The result will heavily depend on the selected location. If the room modes are evenly distributed in your room (you have a room with good ratios), then the effect can be somewhat limited. But if your room has poor ratios (concentrating room modes into single locations), then the AVAA can help you a lot.
The area of effect of the unit is large but still limited, e.g. in my case a whole corner is problematic from top to bottom, which means only 2 units can cover it properly. Unfortunately there is no mounting option, so you have to figure out in this case how do you put the unit (13kg) 1.5m high above the ground.
With 2-3 units the measurements show night and day difference in the whole bass region - frequency and time domain as well. This is indeed the ultimate weapon against room modes. Of course you still have to treat your room for reflections, SBIR etc.

Pros:
- built like a tank
- no setup required
- no sound is emitted, no DSP involved
- works like a tuned absorber, but in ALL frequencies from 15Hz (!) up to 150Hz
- future proof: works in any room, can be relocated easily if conditions/requirements change over time
- the area of effect is much larger than the unit itself or a single tuned absorber

Cons:
- no mounting option
- high unit price
- a single unit most probably won't be enough
- confined spaces, close large objects can make it unstable (yes, this is true)

Like a miracle.

I had some phasing issues in my studio. Heard about AVAA and ordered two to try out and it worked miraculously. I can hear more solid and focused bass than before.
