................... and if they did, i would expect the combo to be ferrite woofer(416-8C) and alnico HF. I've seen more than one pair of 19's with ferrite woofer and alnico HF with owners swearing they're original. I have no clue if they're original, but we even have a member here with such a pair of 19's.

Logically, 802/808 motors were produced in larger quantities than 416-8B. 416-8B's would have been the first component to go scarce, IMO.
