I bought a pair of alnico 2405 slots recently for a steal. They were used in SR applications and the diaphragms have been changed at least once as evidenced by a hole in the rear decal of each driver.
The seller claimed the untis were maintaned by a pro sound company who used only JBL OEM diaphragms. I removed the horns and the units appear to be OEM based on some other dead OEMs I have lying around.
Anyway, is there anyway to assess the condition of the current frams or should I assume they should be replaced and the cores re-maged?
Other than an Ohm tester, I don't have access to other test equipment.
