Thanks for clearing the magnet up.
You're absolutely right, those magnets do not belong on those frames, at least according to the factory lit.

The factory pics from '78 show 515C as having the "old style" motor pot on the new style 16 inch frame.

But, then there's this factory sheet for the 515C: http://altecpro.com/pdfs/vintage/Spe...%20Speaker.pdf

I'm voting "marriage".
