Best way to properly break in a sub prior to daily use is to play FS in free air to around half electrical xmax. At no point during break in do you ever crank it to xmech or you risk damage. Do this for a few hours and it speeds up the process as long as you never exceed electrical xmax.

What is the easiest way to brake in subs after recone, when you have little time to next burp.
how does the expert dbdraggers do it?
Any inputs will be apreaciatet
So now with the question answered heres more food for thought
The reason you do this with most speakers is you have a fresh subwoofer where in alot of cases you have a stiff suspension and it will hold quite tight and you could rip the neck joint,spider glue or spider mound loose without giving it that work in time to ease the suspension.
The type of spiders also will dictate the break in time. Normally if you give it a few hours doing the FS free air at low power you give the spiders to create the stress points needed for further flex/stress. Going to much excursion on the woofer to soon can cause tiny tears in the glue/fibres used to make the spider and thats what manufactures don't want you to do. Also with woofers that use spider spacers and spider mounts that are not direct to the aluminum frame its much easier to break those rings free during the first hours of play if your pushing the limits.
With that said some woofers require no break in time at all. Such as a burp speaker which works best right out of the box and if the score diminishes as it breaks in, it usually means an extra spider or two might be in order next recone.
If anyone remembers that old mtx that was solid when you bought it(you you oldschoolers you know what I mean) I seen many of those break when burped without break in when alot of CV's, RE's etc... never really needed break in time.
I hope that helps.
