They do just that, they operate them. The best makers extensively test
their designs and do excelerated aging tests to produce drivers that
both meet their specs when in real use and stand the test of time.
There is no other way to do it as they or any other system just
doesn't work on the first go as designed from paper initially. All
designs are tested and revised accordingly to meet their design goals
more closely. As makers get more experience, they gather more evidence
and can refer to that rather than start from scratch at each attempt
as a novice, hobbyist or upstart might. They don't share their hard
earned secrets either so those that can't duplicate their efforts
simply dispute them. Try making your own simple pair of two way
speakers from a textbook example and you will see the light, not hear
it...

Hi I though it would be an interesting thread to start.

Burn in of speaker cables, how long for what dielectric. What's
your
experiences?

Bare OFC 5N + PVC +48hrs
Bare OFC 4N + PE about 1 hour
ive not tried Silver+ Teflon yet (need an overdraft 1st)

I have heard half convincing arguments for speaker burn in, i.e. the
suspension becomes more flexible with use I reply how does the
manufacturer
guarantee the final result. But I can see now way that the
performance of
any form of wire will change with normal use.
