It's surprising that the response changed so much (from 63Hz-200Hz) with the addition of the traps (at least to me). It looks like the traps are "tuned" for that bandwidth...
Ethan stated the center frequencies of the panel traps would be approximately 90hz and 150hz, but I was surprized how effective a single wall treatment can be down into the midbass.
I'm probably going to install another 8'x2' midbass trap in the ceiling directly over the listening position; maybe I can get that 50-60 range up into the low 70's; there's definitely a major cancellation in my room in that region.
Sorry I've been such a stranger the past week.
Between building these traps and keeping up with my business, I've barely had time to sleep! (September/October is always a busy time in my graphics business)
Hopefully we can get that meeting together later this week if the phone stops ringing for a day or two.
