Abstract:
In an audio system, a series-configured, capacitor-less crossover network for partitioning by frequency an electrical audio signal as provided by at least one amplifier into a plurality of electrical audio frequency bands comprising at least one high frequency band and one low frequency band for powering a corresponding plurality of electro-acoustic transducers comprising at least one high frequency electro-acoustic transducer and a low frequency electro-acoustic transducer, said capacitor-less crossover network comprising:(a) an input pair comprised of a positive input and a negative input as received from said at least one amplifier;(b) an inductor having a first input end electrically coupled to said positive input of said input pair and a second input end for coupling in shunt with at least one of said high frequency electro-acoustic transducer; and(c) a shunt resistor having a first end electrically coupled to said second input end of said inductor, and said second end of said shunt resistor electrically coupled to said negative input of said input pair and for coupling to a negative input of said low frequency electro-acoustic transducer, said shunt resistor for coupling at least partially in shunt with said low frequency electro-acoustic transducer, said capacitor-less crossover network containing no discrete capacitors for partitioning said audio signals into said frequency bands.
