Infinity Renaissance 90 Piano Black


I am desperate for any help.  I have a very nice pair of Piano Black 90's. I blew the HE-EMIM midrange and can not find a replacement anywhere,  Is there anything I can do ?  can they be repaired?  Im sick over this and do not know what to do.  If I can not fix them what are they worth as parts?  Not that i want to do that at all but i might not have a choice.  Thanks for any help you can provide.

thank you all for your input.  I did take the speaker out that was not working.  I hooked another random speaker to it and it worked.  Would that rule out the crossover issue? 
George i run an ADCOM 555 for them.  Is that enough?  Im somewhat new at this and appreciate all the help.  
@proos - That amp is a little light but Adcom has always had great power output so you should be fine
