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.
