Ummm, I'm a little confused as to what in a tweeter would take 200 hours. I can understand (and have experienced) woofers taking quite a bit of time to break in.
However, here's a good way to break in the entire speaker:
Face them toward each other a few inches apart and wire one speaker out of phase. Play a burn-in CD or one with wide dynamic range and frequency response and set the player on "Repeat". Set the volume level moderately high and then cover the outsides of the speakers with blankets and stuff to reduce the sound. Let them run however long you like.
