Compensating Non-linear Distortion in an 'Equal-Hung' Voice Coil

Non-linear distortion compensation by DSP has been actively research over the last decade. This paper analyses the potential benefits such distortion compensation systems may provide in complete electroacoustic systems. Specifically, this paper compares the increase in amplifier output required by such systems with the increase in sensitivity provided by shorter voice coils. It is shown that a net increase in the sensitivity is provided if a loudspeaker's voice coil height is equal to its magnet gap height, and used over a range of peak-to-peak excursions equal to three times this height.
