PSI AVAA C20 Active Velocity Acoustic Absorber 15 Hz to 150 Hz – Graphite Black
It will do so just like passive absorbers but in a much more efficient way and using up much less space. 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.
