Wow, just stumbled upon this thread. Those look amazing! They remind me of the JBL everest styling.
One minor suggestion, if it is helpful. Early diffraction is the worst type of diffraction for imaging and spatial cues. The upper and lower fingernail where the curved front overhangs the front baffle could cause such diffraction. A very easy fix that would be very aesthetically congruent would be to obtain some high density wool felt*, maybe a 1/4" thick, dye it black if you can't source black already, apply it to this fingernail and trim to profile. It should be visually imperceptible but sonically helpful.
* let me know if you have a hard time understanding the kind I refer to. I sourced mine a long while back and can't recall the exact details, but it looks like a very dense matt not hairy in any way.
