Question about JBL 6-1/2\ Round Coaxial Speaker By Prospec Electronics" Speaker
An easy way to identify polarity is with a 9 volt battery --connect the plus and the minus of the battery to the speaker terminals ---if the woofer pushes out--then the plus of the battery is connected to the plus of the speaker --if the woofer goes in then the plus of the battery is connected to the minus of the speaker and then mark it with a black dot on the speaker to indicate its the negative for the speaker and now you know which is plus and which is ground--enjoy
