Butterworth 3rd order filter
WebSecond-order Linkwitz–Riley crossovers (LR2) have a 12 dB/octave (40 dB/decade) slope. ... They are constructed by cascading two 2nd-order Butterworth filters. Their slope is 24 dB/octave (80 dB/decade). The phase difference amounts to 360°, i.e. the two drives appear in phase, albeit with a full period time delay for the low-pass section. ...

It is also referred to as a maximally flat magnitude filter. It was first described … See more The frequency response of the Butterworth filter is maximally flat (i.e. has no ripples) in the passband and rolls off towards zero in the stopband. When viewed on a logarithmic Bode plot, the response slopes off linearly towards negative infinity.
