Hi Todd,
congrats on the one on the way! just my opinion but if someone was to market a cab that would fit around a stock A7 with furniture grade wood and a nicely done grille I would be interested in two almost immediately, depending on price of course! seems like there is always a lot of talk about WAF and I am including myself in that! the gray utility A7s in the HT room are not the most beloved of my speaker sets. I have actually talked to a cab building firm locally, but the best they had to offer was some kind of engineered looking plywood that wasn't very nice looking. I am a capable carpenter but getting funiture grade corners on large sheet goods is beyond my tool compliment. I also like the idea of a knock down M19. again, it seems like the edges and corners are where most people need the help.
just my .02
