The tale is the same on the 416C, meaning rounded vs. flat magnets?
Yes, round and flat mag versions. Apparently, there were also differences in some of the 416C moving parts during the Telex/EV years.

The various incarnations of 416 i'm not familiar with beyond the B, but i've heard the 515E's of both types in 828 cabinets. I thought the round magnet E sounded nearly identical to 515G. The flat magnet E had the least low extension, and the midrange was dull and lifeless compared to any other Altec woofer, it was bested by 99 dollar(at the time) Dayton 400watt pro cast frame woofers from Parts Express(actually pretty decent woofers).
