PSI Audio AVAA C20 Active Bass Trap

The PSI Audio AVAA C20 is a revolutionary active bass trap designed to transform the acoustics of listening rooms, home cinemas and professional studios without the need for large passive acoustic treatment. Rather than simply absorbing sound like traditional bass traps, the AVAA C20 actively reduces low-frequency room modes, dramatically improving bass clarity, definition and timing while preserving valuable floor space.

Operating entirely in the analogue domain with zero processing latency, the AVAA C20 works across the critical 15Hz–150Hz frequency range to reduce room mode resonance by up to 50%. Installation couldn’t be simpler—just position the unit where bass pressure naturally builds, connect the power, and it immediately begins improving your room without calibration or complex setup. Handmade in Switzerland, the AVAA C20 has become an essential upgrade for audiophiles, recording engineers and mastering studios around the world.
