Wise wisdom from Frank at The Speaker Shop.

I just got back from The Speaker Shop. One of the Heil tweeter diaphragms has to be replaced, the midrange cones need to be stiffened at the edges, and even Frank didn't have the correct foam size for the midrange in stock. I'm going to try modifying a standard size to fit. Theoretically, I may hear one speaker tonight. Frank Fabian is a resource I couldn't do without, and is very generous with his time and knowledge.
