In 2016, PSI Audio released the first active bass trap, named AVAA C20, which is fully analog. From then on, the company continued to develop the AVAA technology. In 2023, the first fully digital AVAA, the AVAA C214, was introduced. PSI is not the first or only manufacturer to produce an active bass trap, as Pass Labs had a large, floor-to-ceiling pipe-shaped active bass trap in the early eighties, and Bag End has produced the E-Trap since 2008. However, PSI did the same for the popularity of active bass traps as Apple did for portable music file players. Furthermore, PSI AVAA is the only solution that works automatically on all resonances, without any adjustments, within 15Hz and 160Hz, in such a small enclosure. While critics will object that digital processing is not 100% real-time, PSI indicates that this is not critical at such low frequencies, as the long wavelengths allow more than enough time for the required calculations.
