ABSTRACT:
A method of operating a single speaker driver circuit having, a low frequency input coil connected between an audio circuit output and the input of the speaker, a low frequency return coil, connected between the return of the speaker and the return of the audio signal, the low frequency return coil being bifilar wound with the low frequency input coil, and a higher frequency input coil connected between the audio circuit output and the return of the audio circuit, and a secondary coil connected between the input of the speaker, and ground, the higher frequency input coil and the secondary coil being bifilar wound with one another and acting as the primary and the secondary of a transformer so the higher frequency signals passing through the higher frequency input coil induce secondary signals in the secondary coil, and a method of operating an audio frequency reproduction system using such a driver circuit.
