ABSTRACT:
A speaker which is driven by an audio amplifier has a feedback coil wound on the coil mandrel adjacent to the speaker's drive coil. A first degenerative feedback element is provided for applying degenerative feedback to the audio amplifier in proportion to the current flowing through the speaker's drive coil. A second degenerative feedback elements is provided for applying degenerative feedback to the audio amplifier in proportion to the voltage induced in the feedback coil. The first and second degenerative feedback elements are arranged to be additive so that the total degenerative feedback applied to the audio amplifier is equal to the sum of the degenerative feedback from both degenerative feedback elements to thereby prevent acoustical peaks from being produced in the audio spectrum of the speaker.
