While on the OEM driver topic, and JBL made drivers for Fender. Some people's understanding is that those Fender are orange color, therefore if not orange then its not a JBL/Fender driver. This is not an accurate way.

True that many Fenders are orange, however JBL made some black drivers too for Fender! On a list page of about 15 Fender drivers, 10 are orange and 5 are black (so 1/3rd). This makes JBL/Fender positive identification or not a little more tricky.

One cannot rely on driver color alone for the black ones, which may or may not be of JBL origin. Then the driver's number needs to be checked, and such number doesn't look like a traditional model identification but instead more like a part number. Bottom line the "black sheep" requires a verification to know for sure. Hopefully you haven't thrown away a black Fender driver thinking that it was some poor speaker, while in reality it might have been a JBL...
