C214 active bass trap

Introduced 2024$3,950 MSRP

The PSI Audio AVAA C214 is an active velocity acoustic absorber — a compact, electronically powered bass trap that uses an internal microphone, actuator, and control electronics to actively cancel low-frequency room resonances rather than passively absorbing them (source: https://downloads.psiaudio.com/active-basstraps/AVAA_C214_UserManual.pdf). PSI Audio states that its AVAA technology allows one unit to achieve absorption equivalent to a passive bass trap roughly 45 times its physical size, making it popular in mastering and mixing rooms where floor space is limited (source: https://www.bhphotovideo.com/c/product/1782498-REG/psi_audio_avaa_c214_active_velocity_acoustic_bass.html).
