So with racing cars: the greater the engine power, the greater the potential drag that the designer must then seek to overcome.

ECONOMIST: CAR DESIGN

Thanks in part to ideas born at dB Drag events, the acoustic power of car stereo speakers has increased tenfold in the last ten years, from a maximum of 500 watts per square meter to 5, 000. (A loudspeaker at a rock concert puts out 2, 500 to 3, 000 watts.) Pioneer learned from dB Dragsters to cover speaker coils with ceramics to dissipate heat.

The lower density means dramatically less drag force acting on the spinning disk stack so that mechanical power into the motor is substantially reduced.
