ム。 In a multi-way speaker system that uses a channel dividing network that divides the input signal into each frequency band and dedicated single speakers that correspond to each frequency band,
As a channel dividing network for frequency band division, an even-order Butterworth type filter composed of passive elements or a Linkwits-type composed of passive elements is used.
In addition to using a Riley type filter, the speaker system has a flat sound pressure frequency characteristic at the front stage of the network, and also has a linear phase (linear phase) phase frequency characteristic.
A multi-way speaker system characterized by inserting an FIR type digital filter and power amplifier for characteristic correction to achieve this.
