Crossover Network Design Formulas & Calculator
This calculator will design a two-way second-order Linkwitz-Riley crossover network for you. If you don't understand what any of the terms mean, click here for help.
Please note the reversed polarity wiring on the high pass filter. Second-order filters will usually give you a better overall frequency response when they are wired this way because this type of filter shifts the phase of the input signal 180°.

Second-Order High Pass Filter	Second-Order Low Pass Filter
Second-Order Linkwitz-Riley Bandpass Filter
C₁ = .0796 / ( Rh x f )	L₁ = (.3183 x Rh ) / f
C₂ = .0796 / ( RL x f )	L₂ = (.3183 x RL ) / f

Calculate Your Crossover Here
To use this form, enter the impedance values (at the crossover frequency) for your speakers, and then enter the frequency you want your filter to crossover at. Now, click the "Calculate Values" button, and your results will appear in the empty text boxes.
