Textbook has that producing bass note requires more energy than high frequency musical notes (e.g. singer level). Some subwoofer need a new electrical circuit to run. What's the theory behind that? Why isn't higher frequency speaker need more eletrcial power instead?

Bass requires more air movement than higher frequencies. To move more air, speaker must be larger with greater lateral movement. It requires more power to drive.

Simple - a subwoofer has a larger coil to energize, a larger, heavier core to move (and it moves a greater distance between its "in" and "out" position), and a larger cone pushing against more air.

the diaphragms are smaller in the high freq and take less power to vibrate.
