Abstract
A driver control circuit ( ) 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 ( ) for connecting with a source of audio signals ( ); a speaker connector ( ) for connecting with a 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 ( ) includes components forming a traditional low-pass or high-pass filter network and a resistive component (R ) connected in parallel across the second series mounted component of the low-pass or high-pass filter network.
