Linkwitz-riley vs butterworth
Nettet10. apr. 2013 · SL is using the LT to shape the low frequency response of the closed box as if it was a 2º order Butterworth (Qtc=0.707). Then, he adds an electrical 2º order Butterworth at the same frequency to build a 4º order acustical Linkwitz-Riley xover in order to cross the box with a subwoofer. NettetThe Bessel and Linkwitz-Riley are the most similar. The Butterworth has the sharpest initial cutoff, and a +3 dB sum at crossover. The Linkwitz-Riley has moderate rolloff …

Produces … NettetThis crossover is recommended over the 2nd order Butterworth type due to its accurate summed frequency response and forward pointing main lobe. Inverted polarity is required for one of the drivers. C1 = .0796 / ( Z x f ) C2 = .0796 / ( Z x f ) L1 = (.3183 x Z ) / f L2 = (.3183 x Z ) / f.
