A system manages temperature and excursion effects on a loudspeaker. Data corresponding to a temperature of the loudspeaker and data corresponding to an excursion (i.e., displacement) of a membrane of the loudspeaker are determined. The dynamic ranges of the temperature and excursion data are compressed, combined, and smoothed. This smoothed data is multiplied with a delayed version of audio data; peak values of the result may be limited. This operation may be performed on multiple frequency bands of audio data. The final output data is combined to form a full-band signal and sent to a loudspeaker.
