Hi juergenk,

Note that now, for constant voltage sinewawes at the system input, the voice coil displacement of the treble unit under the crossover frequency remains constant until its resonance is met, although its level decreases.

That's why I recommend at least 2nd order high-pass for tweeters. First order filters have trouble keeping dome displacement under control.
