Breaking in speakers on bassman

Hi Dave, 

Having received my vintage shure 520 green bullet with controlled magnetic element from Dennis Gruenling yesterday, which sounds fantastic with my windy city 10 plus,  I have dragged my bassman into the lounge to try the mic through it tomorrow (it's evening here now). I also thought I could break in the speakers as it hasn't had many hours use,  by hooking up my phone and playing music through it . Should I have it on any particular settings to get the best results or is it simply the small movement of the cone that does the job.?

It sounds cool as a hi-fi .

Thanks 

Saul
