Hello! I have two cabinet w/ speakers in them, from the Albee Theater in Cincinnati OH. They were auctioned off when the theater was closed and later demolished. One of the speakers is an 602A Duplex and the other speaker isn't marked, but has a 1600A 1600ohm crossover and a serial number (?) marked 20598. From what I can tell, it appears to be a 605A possibly? Can anyone direct me to a good resource for researching this?

Thanks in advance!

Karen
