3723000-4 Speakers. 12 Ohm thin, Size: 2" Diameter, ALNiCo Magnet 

Speakers made with ALNiCo magnets are often raved about as the vintage-certified choice of true tone hounds. The fact that the alloy used to make them is more expensive—thanks to some of the precious metals it includes—than the ferrite used in ceramic magnets also implies a sort of “better than” relationship. ALNiCo speakers are made with magnets containing aluminum, nickel and cobalt.
