speaker break in

It depends on how much resolution your system has.  On extremely high resolution and revealing systems, you may have to go 200-300 hours.  On warmer and softer systems, 100 hours is probably fine.   One thing you need to know is the speaker definitely needs to be played at volume because the suspension on the woofers need to be flexed and broken in as well.  This requires movement. 

It not really a matter of hours but sometimes months. I once bought a pair of Wharfedale Denton bookshelf speakers and they still sounded rubbish two years later.

Thanks everyone. To get the speakers to sound dynamic I have to put volume higher than I want for long term listening sessions. I’m thinking break in is still needed

Why not simply email AP and ask them about your specific model's break in time

Be careful with your new speakers and don’t crank them up to speed the process I blew up one of my twitters after one month because of this !
 it’s better to operate on modest to normal volume at the first 200 hours of break in .
