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.
