PSI Audio AVAA C20 Active Bass Trap Acoustic Absorber???


Hello, Looking to tame an occasionally annoying bass node at about 80hz.
Does anyone have experience with this Swiss device by PSI?

I have been considering other bass absorption traps (tube traps) but location and placement is problematic.

I have stereo REL Carbon Special subs which integrate nicely, yet still boom at a certain spot on some tracks.

I have also played with Roon DSP but not my first choice.

My speakers are YG Hailey 2.2's, with Audionet amps and preamp and Mola Mola Tambaqui DAC.

These units are not inexpensive at $2800 each, and a room my size may need at least 2 or possibly 4 of them, but manufacturer claims way more effective than bass tube traps.

Any experience or thoughts appreciated!

I have a 40 and an 80 Hz mode in my room that I also cannot cure. Did you buy the PSI device and if so, how is it working?

Thanks for the reply. I have moved my 4 subs throughout the room, or at least to the areas Todd Welti has demonstrated as most likely to work, and still have an audible boom. REW corroborates what I hear.  I may pull the trigger.

Very nice system, by the way.
