Greetings -

A question about the cone stamp. It's been my experience that the typical cone stamping for the 150-4C reads 150-101.

I have come across a pair stamped 150-102. Could anyone shed some light on the difference?

This particular pair of -102 have the typical oval label on the back, and the old large red and black push terminals.

Every feature of the speakers look legit, so I'm not suggesting any counterfeiting.
