Knowledge of Linkwitz-Riley crossover/divider network

A Linkwitz–Riley (L-R) filter is an infinite impulse response filter used in Linkwitz–Riley audio crossovers， named after its inventors Siegfried Linkwitz and Russ Riley， which was originally described in Active Crossover Networks for Noncoincident Drivers in JAES Volume 24 Issue 1 pp. 2-8; February 1976. It is also known as a Butterworth squared filter. An L-R crossover consists of a parallel combination of a low-pass and a high-pass L-R filter.
