there's is no break in period for speakers as far as i know, but everytime i do i show, i usually start with my Mackie boards gain ( volume) down to 0 and i gradually raises it up to about 30 and i'll play music for about 1/2hr. and i then will gradually raises it up to the unity gain , i have a Mackie SRM450 powered speakers and i have them on 1/2 way ( 12 o'clock ) to full gain ( volume )the entire duration of my show.. by doing these steps it will prevent me from blowing my speakers from a sudden burst of sound...i've seen people starting up with all volumes turned up and blowing their speakers...i only use my boards faders to turn up/down my vouume..when i used to used a non powered speakers, i had all my amps turned all the way up,( used to have 6 of them ) and still used to do the same steps...
