Active Bass Traps

Welcome to the World of AVAA Technology
​​Our AVAA (Active Velocity Acoustic Absorber) C20 & C214 active bass traps are the solution to unwanted room modes and muddy bass. They absorb excess pressure and reduce resonance time, effectively "clearing the air" so you can mix with accuracy and confidence.

AVAA C20 & C214 use Active ​​Technology to Fight Room Modes​

01. 
Two active bass traps
​Since its release in 2016, the AVAA C20 has proven its efficiency in many types of applications: home studios, recording studios, audiophiles… In 2023, we are once again revolutionizing the world of acoustics with our digital bass trap, the AVAA C214.
02.
02. More effective than passive absorption
Active absorption is up to 45 times more effective than any passive absorption of the similar size.
01. 
03. Easy to setup
​The AVAAs are pressure based absorbers and simply need to be placed in a high pressure location to be extremely effective.
