This easy to use crossover calculator can be employed for the calculation of passive filters (first, second, third, and fourth order) in two-way and three-way crossover networks. It also lets you create a circuit diagram and provide the component values that you require. Here’s how you use it:

1. Choose your crossover type (two-way or three-way)

2. Then input impedance values for tweeter, woofer and midrange (with a three-way crossover network)

3. Now, choose the order/type of the filter- two way or three way, type the Tweeter Impedance (R_{H), }Woofer Impedance (R_{L)}

4. Input the crossover frequency

You can filter the order/type from the available options. These include:

- 1st Order Butterworth
- 1st Order Solen Split -6 db
- 2nd Order Bessel
- 2nd Order Butterworth
- 2nd Order Chebyshev
- 2nd Order Linkwitz-Riley
- 3
^{rd}order Butterworth and Bessel - 4
^{th}order Gaussian - Legendre Linear phase
- 1st Order Normal Polarity
- 2nd Order Reverse Midrange Polarity

Click on the “Calculate” button. The calculator will then simply provide the component values required for the crossover type you have chosen.
