Darrin, woofers cycle hundreds of times and tweeters thousands of times in their first second of operation. Any breaking-in has already happened when the speaker was briefly tested at the factory. You can expect that you'll become more accustomed to the sound of a speaker after a while, but tests show no permanent changes after a very short initial break-in of no more than a minute or so. In any case, you don't have to do anything special, because if there was a "break-in" it would happen automatically.
