Speaker Crossover Calculators

Two-way cross of the first order (6 dB / octave)

High-pass impedance: Ohm low-pass impedance:Ohm frequency Hz
	C1 = μF L1 = mH

An order divider phase shift is 90 degrees

Second-order (12 db / octave) two-way cross

Linkwitz-Riley Butterworth Bessel

High-pass impedance Ohm
low-pass impedance:Ohm
frequency Hz

Linkwitz-Riley Linkwitz - Rayleigh filter
Butterworth Butterworth filter with
Bessel Bessel filter

C1 = μF

L1 = mH

C2 = μF

L2 = mH

Third-order (18 db / octave) two-way cross

High-pass impedance: Ohm low-pass impedance:Ohm Frequency: Hz
