PSI Audio expanded its Active Velocity Acoustic Absorber (AVAA) concept in 2023 with the introduction of the AVAA C214 model, suitable for home audio environments. The PSI Audio booth R09 in hall 3 of the MOC Munich will feature a listening room equipped with AVAA C214 and Héritage3 high-end speakers for visitors to experience the effect of the AVAA. There will also be a special demo box to illustrate its principle outside the listening room.

PSI Audio introduced the AVAA C214, a new active bass trap that evolves from its sibling, the C20. The new AVAA C214 active bass trap eliminates room modes from 15Hz to 160Hz without requiring calibration or tuning, while offering a more efficient form-factor for listening spaces due to the use of digital technology and smaller membranes. Easier to move and readjust when conditions in the room change, the AVAA C214 is the next evolutionary step for the company.
