Abstract:
A driver control circuit for driving a speaker, the driver control circuit comprising:a signal connector for connecting with a source of audio signals; a speaker connector for connecting with the speaker; and a frequency passing circuit coupled between the signal connector and the speaker connector for passing a selected range of frequencies of the audio signals to the speaker and for attenuating other frequencies, the frequency passing circuit including a first series-coupled component connected between the signal connector and the speaker connector, a second series-coupled component connected in series with the first series-coupled component between the signal connector and the speaker connector, a first parallel-coupled component connected in parallel between the first series-coupled component and the second series-coupled component, a second parallel-coupled component connected in parallel between the second series-mounted component and the speaker connector, and a resistive component connected in parallel across the second series-mounted component.
