Question regarding airgap implementation with R30 soffit

Hello all

Longtime lurker.. couple questions:

I have an upper corner that is 28" deep, 22" high and 66" long that I want to trap. R30 seems to be the winner here due to GFR, depth and price point.
Since R30 comes 9" high and 15" deep, I plan to stack three 66" long pieces in a wooden enclosure, which brings me to the question of an air-gap.

The online porous absorption calculator leads me to believe a 13" air gap would perform better than a second stack of R30 behind my first stack.
With this being the case, should I build an enclosure all the way to the wall with the air gap inside, or can I close it after the first 15" deep stack of R30 and leave literal air behind?

Attached for good measure are REW tests in two different listening positions.
While front wall is clearly flatter, the asymmetrical nature of my room leads to poor imaging due to only having a wall on one side.

Note: I have 4 monsters and 6 244s on the way from GIK.. Much of my rear wall is currently untreated, which these are for. I have 4 tri traps in the room, 4 4" panels at reflection points, and 2 2" cloud panels.

Thank you, and apologies for any ignorance in advance.
