Infinity Intermezzo 4.1t Options To Replace Or Repair 3.5" Midrange

I have a pair of Intermezzo 4.1t. I am curious if anyone else has had success with repair or replacement of these drivers. I would be happy to purchase used if anyone had one or more available. The center channel uses the same 3.5" driver. I really like these speakers and would have a hard time replacing them without spending a mint!
