14 ohm 7” midrange driver


I am searching for a ProAc Response 3.8 midrange driver replacement.

I tried ProAc, Seas and Madisound, no luck.  
Does anyone have a suggestion on sourcing a replacement? 
 

Thanks in advance,

As I recall, I was not able to source replacement drivers and I reached out to a number of places.  

Also....I have seen that the drivers are "custom" also.....vs, the Scanspeak standard model.

But that could just be the printing of ProAc on the dust cap. LOL
