Alnicos though. They probably are far from Junk.

They likely sound WAY better than new stuff with a zillion times bigger mags. Can't judge a speaker by it's magnet size. When 604's adopted the bigger mag used on EV's due to corporate policy the woofer bandwidth shifted upward. Those are way less desirable than earlier 604's with smaller mags.

As I understand Great plains has gone back to the smaller mag.
