Rebuiding midrangers on Thiels

Rrog, without going into the details, let me just say that I've had my 3.5 midranges and some other Thiel drivers repaired by Thiel for a much more modest sum.
Though we haven't met, I've heard nothing but excellent reports about Bill of Millersound from people who deal with him often, I'm just outside of Philly.
If one were to choose Bill to do the work, considering the drivers custom mods done for Thiel, and that the Thiel cross-overs compensate for the drivers used, perhaps it would be a good idea to bring the good driver for comparison matching.

I had my 3.5 mid drivers rebuilt by Thiel around six years ago. I think I still have the invoice. I can tell you for a fact that it did not cost $300 per driver. That would make the rebuild cost more than what the speakers are worth. I want to say that it was around $75.00 per driver.

New replacement mid drivers are no longer available from Thiel for this model.

Unsound, Good idea providing you have a good driver.
