Driver control circuit

摘要

A driver control circuit (10) that enhances a steep crossover slope while permitting selective shaping or adjusting of its in-band frequency response with a minimum number of components. The driver control circuit includes a signal connector (16) for connecting with a source of audio signals (12); a speaker connector (18) for connecting with a speaker (14); and a frequency passing circuit (20) coupled between the signal connector (16) and the speaker connector (18) for passing a selected range of frequencies of the audio signals to the speaker (14) and for attenuating other frequencies. The frequency passing circuit (20) includes components forming a traditional low-pass or high-pass filter network and a resistive component (R1) connected in parallel across the second series mounted component of the low-pass or high-pass filter network.
