Abstract

An audio processing system for a multi-speaker system having a speaker and a further speaker coupled to the output of an amplifier is described. The audio processing system includes a temperature calculation module configured to determine a voice coil temperature value of at least one of the speaker and the further speaker, each of the speaker and the further speaker having a respective amplifier-output-voltage-to-current transfer function comprising at least one speaker passband; an audio processor having a first input for receiving an audio signal, a second input coupled to the temperature calculation module and an output for outputting a processed audio signal; wherein the audio processor is configured to selectively alter the amplitude of one or more frequencies of the audio signal within the speaker passband of at least one of the speaker and the further speaker in dependence of the voice coil temperature value of at least one of the speaker and the further speaker. The audio processing system may allow temperature control of multiple speakers using a single amplifier.
