Nettet3. apr. 2001 · Linkwitz-Riley. A specific type of filter ing scheme commonly used in electronic crossover networks. The 4th-order (24 dB / octave slopes) Linkwitz-Riley (LR … NettetA Linkwitz-Riley crossover filter consists of a combination of a lowpass and highpass filter, each formed by cascading two lowpass or highpass Butterworth filters. Summing the response of the two filters yields a gain of 0 dB at the crossover frequency, so that the crossover acts like an allpass filter (and therefore introducing no distortion in the audio …
