employ flat response filters (Butterworth type). The
group delay characteristic of this type of filters is
much worse than that of the linear phase filters, and
this cauees transient distortion in the audio signais at
each fitter's crossover
frequency. To reduce that
distortion and to obtain hi-fi sound, linear phase
