The characteristics of this filter is up to 4 stages attenuation slope, in other words, every one octave frequency sound energy will be attenuated 24dB, i.e. attenuation slope of -24dB / Oct (Oct ie Octave, an octave interval of the mean). Meanwhile, in the entire audio band (20Hz-20kHz), Linkwitz-Riley filter has a very flat phase response, which is far better than Butterworth filter after filter signal, no phase distortion, which is widely admired by audiophiles.
