Thanks for the info.
Care to detail some of those differences?
I guess the winding itself must have remained about the same (maybe with a newer adhesive).
Is it Edge Wound Aluminum or Copper?

Apart from high temp glues etc, EV also changed their testing method over the years, from their own band limited pink noise test to various EIA, AES and ANSI standards as they came out. So you even find different power ratings for identical drivers...
Looking at the EDS's for various models over the years is quite enlightening.
