Abstract
An audio crossover circuit for use with audio speakers is disclosed. The audio crossover circuit includes a pair of inductors that are series connected and inductively coupled and a pair of capacitors. The inductors and capacitors cooperate for achieving a low-pass crossover slope in excess of 30 dB/octave within one half of an octave of the crossover frequency, thereby eliminating the need for additional inductors and capacitors. The crossover circuit also includes a resistor in series with one of the capacitors for further enhancing the crossover slope beyond an octave above the crossover frequency.
