I have the following and am wondering if they were made by JBL and is there any value to them.
1950-1960's Dukane 15" Low-Boy Speaker model 5A425
Dukane Spectra-Phase-12 5A440

Well it's definitely not a JBL. Could be an Altec with the vent through the cap. Is that a cast frame or a stamped. Stamped is thin cast is at least 1/16 thick or more usually aluminum.

1950 -1960 ferrite magnet :o:
