New woofer suspensions loosen up a bit with playing time, and are more likely to achieve the response they were designed to do once worn in a bit. Depending on the speakers and the rest of your system, the crossover may experience some audible improvements from burn in too. You can just give them playing time and enjoy the process, or you can pump them with low frequency signal to move the woofers.
Speaker massage ...
Hi there
I don't know how to translate this on english, but new speakers are getting better even more they got played, but how? How do I give them the perfect massage? Do they have to be played loud or on normal sound niveau but for hours? I live in an apartment and can't play loud every day, with respect to the neighbours.
Best regards
