Rebuiding midrangers on Thiels

Call Bill at Millersound.

Send them to Thiel. The Thiel drivers though appearing to be stock items are actually modified to Thiels specs. The midrange drivers for the 3.5's are a bit unusual in that they use paper surrounds. Though out of warranty, Thiel is rightly famous for their customer service, and typically pretty generous with regard to such repairs so long as the drivers weren't abused.

Thiel charges $300 each plus shipping to repair 3.5 mids. I would definitely check with Millersound before spending more than $600 to repair an $800 speaker system. If you are not familiar with Bill (Millersound) he is third generation in the speaker business and all of Bill's work is first class.
