Maniacally is the perfect way to describe this.
I'm driving everyone around me crazy.

Anyway,
No, I don't have any corner trapping at the moment.
I'm going to do the super chunks as soon as the Roxul truck arrives.
I'm going to start by doing the front verticals and the wall/ceiling in the front and the back.
After that, I'll probably do the side wall/ceilings.
I have structural obstacles in both back verticals.

Warning:
Information Diarrhea Forthcoming.

I messed around with putting 4" 703 panels in vertical corners, but I couldn't get them to have any effect.
I had made soffits that were 8'H x 2'W x 18"D out of R30 in the front vertical corners.
They had little or no effect.

Right now, the only absorption in the room are as follows:
Front wall completely covered with 12" R38 kraft paper out.
Some 2" and 4" 703 panels that start at the front wall and go back 6' on the side walls that are 4' high positioned for RFZ.
A 4'x8'x2" ceiling cloud position for RFZ.
A 8'H x 6'W x 18"D section on the back wall of R38, that I don't think is doing much of anything.
There is carpet over the all of the floor except the front 3' or so... where the speakers are.

No matter where I move the speakers I have one or both of two problems.
Problem 1: Null at 60Hz
Problem 2: Nulls at approximately 115Hz, 150Hz and 300-350Hz (it moves).
I do have a console that is about 6.5' long and 3' deep.

With the speakers as far away from the front and side walls as possible the low end response is VERY flat down to 80Hz. At that point the 60Hz null is at it's worst and pulls the response down to -30 @60Hz.

With the speakers almost all the way into the corners, the 60Hz null is almost gone, but the three amigos (115, 150 and 300) are at their worst.

Right now, I have the speakers in the middle of these two places so that both problems are about even and the lowest dip is about -12dB @ 60Hz and around
-10dB for the three amigos.

I am playing around with the idea to use two sets of speakers instead on one pair. One set on the meter bridge (as "nearfields") to get the flat down to 80Hz response, and then a set in the corners (as "mains") to get the thump of 80Hz down.

I know that I need more treatment, but I am skeptical that the 60Hz problem will ever be solved enough.
From what I can tell, it may be a 1,0,1 mode.
The dimensions are 20.4'L x 13'W x 10.75'H.

I have not done any RT60 analysis as of yet.

Thanks,
Seamus
