Abstract
A speaker excursion characterizing system for a speaker includes a signal generator configured to generate a signal at a plurality of different amplitudes. The signal may be generated at a plurality of frequencies. An inverse excursion filter has an inverse excursion filter response, receives the signal and applies the inverse excursion filter response and has an output in communication with an amplifier circuit of the speaker. The inverse excursion filter response is an inverse of an excursion filter response of an excursion filter in the amplifier circuit of the speaker.
