Abstract:
In an audio system, a series-configured, crossover network for partitioning by frequency the 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 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) a first inductor having a first input end directly electrically coupled to said positive input of said input pair and a second input end, said first inductor for coupling partially in shunt with at least one of said high frequency electro-acoustic transducer; c) at least one series high frequency band waveshaping element for coupling in series with said high frequency electro-acoustic transducer and together which are for coupling in shunt with said first inductor; and d) a shunt resistor having a first end directly electrically coupled to said second input end of said first inductor, and said second end of said shunt resistor electrically coupled to said negative input of said input pair and for coupling to the negative input to said low frequency electro-acoustic transducer, said shunt resistor for coupling at least partially in shunt with said low frequency electro-acoustic transducer.
