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?

No I did not buy these.

 

I did two things:

1) switched the subs to wireless so I could move them around.  Made a big difference getting them outboard of my main speakers and angled towards the front not pointed straight to the rear.  They were booming back off the rear wall.

2) I got a good deal on some corner traps and round traps used put them in offending corners.  It made a huge improvement.  Good Luck
