1. A system comprising: a controller configured to be coupled to an audio speaker, wherein the controller processes an audio input signal based on a displacement transfer function associated with the audio speaker to generate an output audio signal communicated to the audio speaker, wherein the displacement transfer function correlates an amplitude and a frequency of the audio input signal to an expected displacement of the audio speaker in response to the amplitude and the frequency of the audio input signal, and wherein the controller adaptively modifies the displacement transfer function based on one or more parameters of the audio speaker.
