I'm not a big believer in "breaking in" speakers either, but
the post quoted below about track thirty on the Autosound test disc
might not have anything to do with break-in.
It specifically said that the tones were for "exercising
woofers before making Small/Theil parameter measurements". That's not
the same as "breaking in" woofers. T/S parameters change
significantly when the speaker is warmed up for a while, and the
parameters go right back to their original values once the speaker
cools back down.
My interpretation of the liner notes has always been that
track thirty is just for warming up speakers so you're not measuring
T/S parameters off of a cold sub.

BTW, I've heard a poster in another group that swore that whenever he
bought new home speakers, they always sounded different once he'd
played them for about a month. Then, he bought a pair of store demo
speakers that already had a few hundred hours on them. Guess what?
They sounded different after a month in his house, too. That's when
he figured that "speaker break-in" is more about our ears adapting to
the speakers than any actual change in the speakers themselves. My
experiences have been similar to his.

Richard Clark started a lot of hype. Clark and his coat-tail riding
