Abstract
A system may include a first input configured to receive a playback signal to be played back to a transducer, a second input configured to receive temperature information associated with the transducer, and a thermal-controlled gain element configured to determine a sub-band gain to be applied to a selected frequency band of the playback signal, wherein the thermal-controlled gain element determines the gain based on the temperature information and apply the sub-band gain to the selected frequency band.
