Very nice looking layout of those panels.
But if you really want to tame the room, you need to add thick area rugs.
At least between the LCRs and the seating.
I live in an all concrete house (all that way here). And I do have panels along my right wall, behind the curtains. The other side is not a real problem.
And my LCRs are a minimum of 4 ft forward of the wall behind.
The biggest improvement was when I bought more area rugs. Hard horizontal surfaces cause more problems than vertical surfaces.
I have an 8 ft ∅ rug in the middle. It is quite dense (think of a tightly coiled rope).
I just recently bought three more thick rugs 1.2m x 1.7m and have them side-side making a carpeted area of 6' x 12' completely covering the area between the LCRs and seats, with the round rug acting as the carpet pad underneath.
Below is from: Perceptual Effects of Room Reflections

The most surprising was scenario #4 where the outcome was “greatly degrading effect.” Let me repeat: the same distortion created electronically and sent out of the speaker was a very negative thing. The reason is that when comb filtering is created that way, we don’t get the nice benefit of the image widening, or the psychoacoustic factors that reduced its severity. This is how Clark concludes the paper:
“Two speaker mono was considered superior to the one speaker, one path mono. A reflection from a vertical surface was barely audible but a horizontal reflector was more audible. An electronic delay comb filter was highly audible and annoying.”
