While looking at the Salk web site to remind myself of the Soundscape 8 for a different thread, I looked around a bit more. Everything looked as expected until I read about the Exotica 3 speaker, and read about its use of alnico magnets:
Long the favorite of vintage audiophiles, Alnico magnets work differently than typical ferrous or Neodymium magnets and result in smooth engaging sound.
Other than being weaker than neodymium and allowing the casting of complex shapes, how does alnico "work differently" than neodymium or the more common ferrous slugs used by other drivers?
