It's a simple reason if you have the math background: signals with compact
support in the time domain have infinitely long tails in the frequency
domain. By having more high frequency range, you improve the temporal
response of the transducer.
At the ends of the frequency range, the group delay becomes significant and
shifts some components of the signal more than others. A wide-band
transducer with high damping is better able to reproduce the signals that
you feed it, but also loses some of its capability to deliver power.
