Properly made - just fine. Needs some updating of crossover
parts and new surrounds - easy to do.

I own some University 315-C's made ca 1960; surrounds are cloth.
No problems with either the cones or surrounds.

I had to repair a Jensen G610B many years ago when the back-to-back
electrolytics used as crossover caps failed.

Lastly - I think most of the "break-in" myth was started by people
in the 70's and 80's listening to Alcino magnet speakers. They do

Bookshelf speakers from the 70's and 80's used ferrite magnets, and
not AlNiCo. Professional speakers from the 60's, at least, used
AlNiCo magnet structures and I doubt that they changed much over
time.
