There 3 or 4 version of 250 speakers, 3 TIs i think including European version and 1 set that was Charge Coupled from the factory. Part of the confusion comes from JBL switching to the current standard or polarity during the time the 250 series was built. Original woofers went inward when touched to a battery to test, positive terminal to the positive battery . It switched at some year but i would think your version is past the switch. I was never (and still am ) sure if I have polarity each driver 100% correct.
you have gold tweeter , never let it go!! rare
