HI QuadD,

Which bass freq. did you have trouble eliminating with the QRD's and diaphragmatic absorbers?
Did you measure your room before and after applying the PSI AVVA's or did you do it just by ear?

Regards,

Geoff

Using its staggered 4-mic array, my Trinnov Amethyst captures data in multiple domains, including height/distance azimuth, phase, timing, and frequency. Let me try to dig up some screenshots to demonstrate how the AVAAs have been effective in reducing undesirable room resonance (mostly in multiples of 35Hz) present in the rectangular space (extension of my lining room into the balcony) to the R of my R loudspeakers.

First post!

I just picked up the PSI Audio line for my audio business and have 2 in my 26'x17'x8' audition room. They really are interesting and have made quite in an impact. I have found that placement is a bit tricky and not what I originally thought, but the results are very good. If you are in the Mineeapolis area, come over and play with them yourself!

So, not in corners? Not in front corners?

My room runs to 18'x43', clg ht varies from a 4' at side walls up max of 9' at midline apex.

Hi! My wall is made of concrete. There is no deep sound where you sit, but if you walk in the room you may be deaf from elsewhere.
What can I do?
