As I posted earlier I planned on using five 2' X 4' X 4" OC 703 panels
Four are placed across the front and rear ceiling/wall corners, against the side walls
The fifth is behind my listening position

I have two 15" X 5'(front corners) and two 12" X 4"(side walls) ASC type traps. My measurements were taken with the same software, @ 80db. The only differences between the two graphs is that an ECM8000 Mic was used for the second measurement after the panels were installed and an old RS SPL meter did the duties for the first measurement. The proper calibration files were loaded for each measurement

I can't believe the extension the second graph shows because I am not driving my Gallo Reference3's woofers second voice coils.

I am planning to minimize any humps with a DEQ2496 when I get the room as good as I can(with in my limits)

Can you tell me what is going on here??

Here's the original graph

This one is after the panels were installed

Thanks for your help!!
