Driver 'break-in' period

[phase_accurate]

I asked the manufacturer of my drivers for his opinion on that subject. He answered by e-mail and put the answer on their FAQ as well.
So here is the answer of someone who has actually built many thousands of fine drivers and developed some hundred different types:

Nobody disputed the T/S changes. What is disputed is Spectral changes over time. Nobody has ever proven that this happens.

Anyone who is satisfied by a handwaving statement and a stupid analogy (drivers are not beverages, and not all fine wines improve with age) is not truly a curious person.

I say again, the fact that the changes in sound are anecdotally always to the better indicates that accomodation is the reason for the break-in phenomenon.

Well, T/S changes have been documented elsewhere to be pretty stable over time and with "break-in", having a correlation predominantly with operating temperature.

Of course did some lately. Thats the reason why I asked Per Skaaning about his experience.

TSP do of course influence both the temporal behaviour and the behaviour in the frequency domain. The latter over a small range of course, but if you have multiway speakers ...........

I think I am curious enough. My actual question was definitely answered in a professional manner
The wine statement, although not very technical, isn't that disturbing anyway.
