See the PSI Audio AVAA C214 in Action Discover how our digital active bass trap transforms room acoustics in a real-world test. In early 2023, we released the AVAA C214 — our new digital active bass trap, designed to control bass precision in your room. Simply place it where the bass resonates, and it will [...]
PSI Audio AVAA C214 eliminates room modes with maximum efficiency PSI Audio continues to turn heads with its AVAA technology. The new active bass trap AVAA C214 expands the AVAA family by a now digitally controlled variant of the original C20. The C214 is more compact and can be adjusted in its sensitivity through a [...]
10 Years of Active Bass Absorption 2026 marks an important milestone for PSI Audio: 10 years of AVAA active bass absorption. When the first AVAA C20 was launched in 2016, it introduced a completely new approach to controlling room modes and low-frequency problems. Originally developed for home studios and compact listening [...]
AVAA C20 review by Sound on Sound Operating rather like a subwoofer in reverse, this crafty device controls low frequencies but takes up far less space than conventional bass traps. Without doubt the most difficult acoustic problem to resolve for the vast majority of project studios is the challenge of low-frequency standing waves [...]
What is RT60 Reverberation time, also known as RT60, measures the time it takes for sound to decay in a room after turning off the sound source. It defines the time required for the sound pressure level to decrease by 60 decibels (dB) from its initial level. Evaluating a space's sound quality, reverberation time [...]

Why are low frequencies difficult to treat? Acoustics is a fluid dynamic. Unfortunately, it is impossible to see what is happening with small pressure waves in air. Waves in water are a good analogy and the 2 pictures hereunder make it easy to understand why short wavelengths are easy to deal with and big [...]
What are room modes? Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker. Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or [...]
