14 ohm 7” midrange driver

@foeraus

If you are handy with a soldering iron and software, use REW wizard to properly measure the driver impedance.  Otherwise get DATS V3. 

It drives me nuts to see people spending weeks on a problem the right tool could solve immediately.

I was fortunate to find a guy who could repair mine. 
He did great work and there is no inconsistency between the left & right speaker.

The speakers are still working today , quality work.

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

Good info. Thanks!

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
