PSI Audio AVAA C214 Active Bass Trap

The AVAA C214 harnesses PSI Audio's innovative AVAA technology, designed to effectively eliminate disruptive bass resonances within the frequency range of 15 Hz to 160 Hz. What sets it apart is its ability to achieve an equivalent absorption area up to 45 times its physical size. Remarkably, this breakthrough is achieved without the need for calibration or tuning. AVAA Technology If you want to fight room modes, passive absorption is what first comes to mind. But treating low frequencies requires a lot of space and tuning to be effective with any passive system. If your room size is limited, active bass traps is the solution with the following benefits: extremely compact works on a wide broadband (15 – 160 Hz) doesn’t dampen higher frequencies extremely effective can easily be moved from room to room robust long-lasting product What AVAA's do The AVAAs actively absorb standing modes in a room, specifically those between 15 and 160 Hz. Unlike passive absorbers, the AVAAs achieve this with greater efficiency and in a much smaller form factor. With each AVAA in operation, the effect is equivalent to a much larger hole in the wall – typically ranging between 25 and 45 times larger than the AVAA’s actual size, depending on the frequency and environment. By lowering the acoustic impedance of the air in front of it, the AVAA effectively sucks in low frequencies over an area of about 1 to 1.5 meters. As a result, the optimal position for an AVAA is in the most rigid corners of the room, where pressure is highest and where room modes are most present. It’s important to note that while the AVAA improves room acoustics, it has little impact on the inevitable first reflections of sound. Therefore, proper positioning of loudspeakers and listening equipment is crucial for achieving the best possible sound quality. Reviews SixMoons Hans Beekhuysen
