Epicure Masonite Tweeters Polarity

[nniemiec]

Has anyone else noticed no consistency at all regarding polarity on these? Using a 1.5v battery to test - I'm noticing the terminals are not all wired / terminated the same - assuming I'm doing this right? = correct orientation results in the inverted cone moving out? sometimes (+) is on the right side, sometimes on the left side. Am I missing something or just the way things were done back then?

How do you determine left and right side? Yes, that is correct, positive on the battery put to the positive terminal of the driver pushes the driver out.

I don't know how the factory did it but they would mark the positive terminal somehow. Whether that be a marker, sticker or size of the connection, different methods for different companies. If they are still marked, you can check them. If not, just test em and mark em.

Most of my Epis have had a little round red sticker somewhere on one side of the back of the tweeter, but oftentimes that little sticker can be found in the bottom of the speaker cabinet, having fallen off at some point.
