I have conducted several experiments in break-in covering periods as long
as
150 hours. What happens is that you can measure a fall in system or driver
resonance by several percent along with an increse in compliance of a like
amount immediately following an extended break-in period. However if you
allow
the driver/system to rest for several hours you'll find that the unit
returns
to its 'fresh' values.

How about crossover? Do they need break-in?


..... As it turned out that was 7-calendar days (meaning
that a speaker purchased on Monday had until Saturday to get returned but
if
you bought on Tuesday you had a full week) so that meant that in order to
'reach' the speaker's full potential a new owner would have to
use/break-in the
product for 6.25 days non-stop to find out if they 'sounded' as good as he
was
lead to believe..

Most decent High End stores give about 3 months to return a speaker.

cheers.
