I pulled the alnico Weber Blue Pups that came with my '64 Vibrolux Reverb in favor of new, more period correct, ceramic speakers. I've been playing an iPod through them at between 4 & 5 on the normal channel. Roughly, how long will it take to break in the speakers? Does increasing the volume significantly reduce the breaking period? On another note, do the speakers have a memory? I'm looping Allman Bros. at the Fillmore East was hoping I'll get the same sound when I play though the amp.
