Hey Guys,
Thanks for all of the additional info....
So I rearranged the room again, putting the record shelves along the side walls. This is going to allow for better placement of panels on the rear wall.
I have yet to do another baseline of this arrangement.
Superchunks are also in the works for the corners. Do we recommend also doing straddled OC703 panels in the upper wall/ ceiling corners? If so, what thickness?
Ill post the new baseline when i get a chance and will keep yall updated as i work.
Thanks for your help.
Erik

To minimize material loss making superchunks, here are the 3 sizes of superchunk DIY construction designs I have seen used based on 2'x4' panels (fills corners with no air gaps).
The front face width (hypotenuse), panel to row layers and stack heights (assuming 2" stock) are:
To make the 48" wide version just stack 2 smaller triangles to make a single 48" face layer.
Some people use the 1st design to fill the triangular gap and place one (or more) whole vertical panel in front of the stack to smooth out the cut edges and increase the depth.
The non-superchunk versions use vertical panels (sandwiched together, with or without a front FRK membrane) straddling the corners with triangular air gaps behind (most economical versions).
Hope this gives you some ideas.
Internal diagonal and vertical lines are cut lines.

If you don't want to move your speakers then build around them. The room's front is prime real estate for absorption. Regarding the exact form and placement of absorption, experimentation is your friend. More is usually better but specifically what form that takes and where and how those forms are placed is up to your room's unique acoustic interaction. It'll be easier if you just build some stuff that can go in a few places. I've got 9 31"w 4'h super chunks (halved 23" insulation) and 20 4" 8lb roxul panels. In my current room, it just so happened that fully treating my rear wall defeated the room's Z axial mode which serves to neutralize my X axial response. In other words, I took my rear panels down, put 'em on the side, angled, and now I'm good. The only thing I'd do differently is not make super chunks but, instead, make rectangular soffits. Why? Because more is more!

I placed my mineral wool bale above the speakers. They almost touch the ceilling and it help.
