Until RMAF this year I was not even familiar with GIK treatments. I am a believer now. Last year the very large room we were in (Iris) was a mess acoustically. Lots of echoes and bass nulls and peaks. We did the best we could programming the DEQX to compensate.
This year was a completely different story. Same room, but with GIK treatments thanks to Bryan Pape and Chris Hoff who recruited Bryan. Difference was night and day. The walls simply dissappeared. First time at any show I felt like I was in a really large concert hall.
Also, the WAF was huge. The panels behind the speakers had superb stratocaster graphics. We own them now.
