Covid-19 and storm Isaias are probably not helping.
We just got our power back after 2 1/2 days. Ugh.

First, I want to make sure I'm see things the right way: SoulShaker-room-question-1.jpg Is that correct? The LR is over on the right of that photo, beyond the wall, the CR is on the left, the pink insulation and framing visible in the middle is the inner-leaf of the LR wall, and the other wall (closer to the camera, drywall and framing only, no insulation, built inside-out) is the outer leaf of the building itself?
If that's correct, then my next question is: Why is that outer-wall there? Is that a structural (load-bearing) wall that cannot be moved? From the photo, it doesn't seem to be structural. Or at least, there's no framing visible that points to it being load-bearing. So, if it is not load bearing, then wouldn't it just be easier to remove it? That way, your CR could be built in the normal way, and you'd only have two leaves.
Now, if that really is structural and cannot be removed, then probably the best thing to do would be to ignore it: pretend it's not there, and just build your CR in the normal way.
However, the other photo that also has me a bit confused: IMG_3523.jpg If all of that is your outer leaf, and you now want to build your CR within that shell, then all of that drywall on the ceiling and other walls should probably not be there! You should just have bare framing there. Because on the other side of that drywall there is framing (I assume), and on the other side of that framing you must have the outer sheathing of the building and the sub-floor for the room above, so the drywall visible in this photo is going to create a three-leaf system in those directions too, it would seem. Is this because you have no choice but to do three-leaf up there? IS it because you have a ventilated roof up there? The CR is your existing garage, right?
I'm still trying to understand what you are dealing with, so I can suggest how to proceed, so please confirm the above...

https://www.jochenschulz.me/en/blog/roc ... r-material
Here are the room modes identified by Amroc. There's no capability for a sloping roof so I put 11 feet as an approximation. Therefore take calculated modes involving the height dimension with a pinch of salt. From https://amcoustics.com/tools/amroc?l=27 ... 60=0.2room modes.PNG
First mode is length, 21Hz and is below the pitch of most (all?) musical instruments so probably not a concern.
Next is 30Hz, width, and is getting into the musical range. The low B on a 5 string bass guitar is just a little bit higher than this. The second order width mode will be about 59Hz and is definitely in the useful musical range - kick drum fundamental, normal bass guitar. I don't think your current scheme will do much to address this. If you'd like it to, then consider more deep / low density traps where they'll have an effect. Superchunks in the places marked red would help with width a bit, and also length. Make them big and deep though, with low density insulation. Perhaps a couple at the other end of the room as well. If still required after this, go with deeper dedicated traps on the walls you have marked green instead of gobos.
42Hz is the second length mode. Your deep low density trap marked black will address this well. 24" is a minimum, if you could get deeper still it might be worth it.
51Hz is our guess for height, so take with a pinch of salt. Your cloud will address this well if you choose the absorption material wisely.
If you get these ones sorted enough I reckon you'll be close. The rest will be up to taste.
I don't know much about diffusion, sorry

It can be 31" Deep which would bring it out flush with the end of the small wall on right near doorway. It can come down 5' from top of ceiling and can span across the whole back wall of room which is 14'.
Do you think behind the low density insulation at the very back of black trap that it could benefit from a 2” layer of high density rigid insulation?
On the ceiling cloud you said choose the absorption material wisely. What do you recommend?
