My research has shown you can't have enough bass traps.
First Reflection Zone treatments will be my next venture, as soon as I build my rear bass trap columns. Need to make the wife happy and she doesn't want me to do superchunks in the rear. For the ceiling/wall corners on the ceiling I'll most likely use 4" thick OC703 staddeling the corners. 2" 703 for the RFZ.
I would also recommend downloading the FREE Real Traps tones which span from 10hz to 300hz in 1hz increments, those are the graphs I show in my superchunk thread below yours.
I'm experimenting right now with Room EQ Wizzard, which is a free download from Home Theater Shack. I think it is as good as ETF, a purchased product.
