I see a few IMMEDIATE problems with those things.
Those long, unbraced glass panels will ring audibly. Being of several differend widths, they will ring at several different frequencies, adding colorations or distortions at those frequencies to the direct output of the drivers.
The hard, slick baffle will be highly reflective at higher frequencies, leading to audible diffraction issues. I can already hear these, in my mind's ear, sounding "hard," "glassy," and "glary." Jim G. could whip up some nice felt baffle pads for 'em that would alleviate the problem somewhat, but of course that would compromise the "looks."
What about internal reflections and resonances? There is NO internal lining of acoustic foam or felt, and NO stuffing of Dacron, fiberglass, wool, etc. (which would ruin the "looks"). The irregular internal shape will mitigate standing waves somewhat, but the long tall column (regardless of cross-sectional shape) will still have an "organ pipe" resonance, and undamped reflections will still hit the back of the woofer cones, albeit at a greater multitude of angles and frequencies than would be the case with a rectangular cabinet.
Let us assume that the drivers are of the highest quality (sorry, I don't recognize 'em offhand, but that ribbon tweet looks nice), and that the crossover was well designed by a competent EE. The cabinet problems, noted above, will still seriously compromise performance.
