Abstract:
In an audio system, a crossover network for partitioning by frequency the electrical audio signal as provided by at least one amplifier into a high frequency band and a low frequency band for powering a corresponding high frequency electro-acoustic transducer and 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 end electrically coupled to said positive input of said input pair and a second end for coupling to a first terminal of said low frequency transducer;c. a second inductor having a first end for coupling to a second terminal of said low frequency transducer and a second end electrically coupled to said negative input of said input pair;d. a first capacitor having a first end electrically coupled to said positive input of said input pair and a second end electrically coupled to said first end of said second inductor, said second end also for electrically coupling at least indirectly to a first end of said high frequency transducer; ande. a second capacitor having a first end electrically coupled to said second end of said first inductor, said first end also for electrically coupling at least indirectly to a second end of said high frequency transducer, said second capacitor also having a second end electrically coupled to said negative input of said input pair, said low frequency transducer coupled at least partially in parallel with said high frequency transducer.
