Michael, for the record, the "hump" that I eluded to would be on the outer baffle...the cabinet would be standard Axiom style with flat angled sides, but with another, separate baffle with a CNC'ed hump in the middle attached. The second baffle is a separate piece, the same size as the standard baffle(which is folded and glued up like the standard cab's) but with the extra material in the middle to house the tweet above the midrange.

Perhaps an alternative would be to add a small appendage to house the tweeter on top of the cabinet, glued and screwed from inside the main cabinet. This could be done in black for all the cabinets, no matter what finish the customer chooses on the main cabinet. The "appendage" would only be the size of your fist, or thereabouts.

Half of communication is listening. You can't listen with your mouth.
