Abstract:
1. A crossover network for a loudspeaker system comprising: a low-frequency driver (woofer) and a high-frequency driver (tweeter), comprising: a) a low-pass filter having a low-pass filter frequency response operatively connected to a signal input and to said woofer for providing substantially only low-frequency signals thereto, said low-pass filter comprising a pair of mutually-coupled coils so as to generate a transmission zero in said low-pass filter frequency response so as to produce an upper frequency slope that is greater than or equal to 120 dB/octave; and b) a high-pass filter operatively connected to said signal input and to said tweeter, said high-pass filter having a lower frequency slope less than 120 dB/octave.
