PROBLEM TO BE SOLVED: To provide a channel divider that can change reproduced sound quality of a multiway speaker system by appropriately setting an overlap of reproduced sounds from a woofer and a tweeter in the vicinity of a crossover frequency.SOLUTION: The channel divider comprises: a low pass filter and a high pass filter; a bandpass filter for setting a lower limit cutoff frequency equal to a cutoff frequency of the low pass filter and an upper limit cutoff frequency equal to a cutoff frequency of the high pass filter; a first comb filter and a second comb filter for receiving an output of the bandpass filter; a first adder for adding an output of the low pass filter and an output of the first comb filter; and a second adder for adding an output of the high pass filter and an output of the second comb filter. An output of the first adder is a first output signal, and an output of the second adder is a second output signal. |
