I do not understand why it is not considered plausible, in some circles, for the beginning of this process to be apparent, even if it is in small degrees, just as the end of this process is apparent.
But what about the part that comes between the first change and the last change, that part that basically equates to the lifetime of the speaker? If break-in (or slow break-down), really does occur, then you should be able to notice it constantly throughout the life span of the speaker.
How does a speaker know to stop breaking in after the first 48 (or so) hours, and then wait 10-15 years before wearing out altogether?
And the thing with rubber surrounds is that they either do the job or they don't. If anything, they should affect the sound negatively (by resisting movement) as they age and dry out. If anything, speakers should sound best straight out of the box if it's the driver surrounds that are changing. Do you see where I'm coming from?
