Abstract
A speaker system includes a speaker driver configured to cause speaker cone displacement based on a driver voltage input. A controller is configured to generate the driver voltage input to the speaker driver. The controller includes: a feedforward control path configured to generate a nominal voltage input based on a nonlinear model of electroacoustic dynamics of the speaker driver and an input audio signal.
