IIRC you need a bias voltage in the range of like 500V DC for electrostatics, and popular amps claim 1000V+ peak-to-peak (a few hundred rms) voltage swing. Those levels are higher than speakers, but the power consumption is not necessarily. I guess the impedance is not as low, or actually, I'd need to check the method of operation. I don't really know much about them either.
