RE: is speaker break-in real?

When i replaced the diaphragm in my right Beyma CP25 compression tweeter (diaphragm is an aluminium ring), leaving the left one untouched, the new diaphragm sounded noticeably more harsh and peaky (subjectively louder), shifting the stereo image to the right. it took a couple of days before it started to sound like the left tweeter. They now have the same output and i could swap them without noticing.
When I replaced my old Atlas/klipsch midrange drivers with some brand new JohnAllen A55G, the first hours were quite disappointing and it took about 200hours before they completely opened up, largely surpassing the old Klipsch drivers. The first minutes were actually horrible, they sounded more like siren drivers than the Klipsch/Atlas (actual siren drivers... haha) ever did!
