The AVAAs actively absorb standing modes in a room, specifically those between 15 and 160 Hz. Unlike passive absorbers, the AVAAs achieve this with greater efficiency and in a much smaller form factor. With each AVAA in operation, the effect is equivalent to a much larger hole in the wall – typically ranging between 25 and 45 times larger than the AVAA’s actual size, depending on the frequency and environment.
By lowering the acoustic impedance of the air in front of it, the AVAA effectively sucks in low frequencies over an area of about 1 to 1.5 meters. As a result, the optimal position for an AVAA is in the most rigid corners of the room, where pressure is highest and where room modes are most present.
It’s important to note that while the AVAA improves room acoustics, it has little impact on the inevitable first reflections of sound. Therefore, proper positioning of loudspeakers and listening equipment is crucial for achieving the best possible sound quality.
