I don't agree with the thought that these vintage speakers. They are vintage cabinets. The woofers and their amps are modern so are the crossovers.
The EMIM's were updated with modern versions of the diaphragms by Corydon Johnson and the EMITs have replacement diaphragms (and I assume updated magnets).
I never listened to Paul's updated ones but I have listened to some originals and they are amazing.
