Does anybody know anything about this 12 inch loudspeaker? It is in my
guitar amplifier. What is it worth, and is it any good? 8 ohms

Essentially an updated version of the 417 with a ceramic magnet.
Sort of the 12" baby brother to the 421A (15"), an excellent
PA/guitar speaker. Very efficient and durable.
Competitor to the EV and JBL offerings of the era.
I think these have a 3" VC.
