The following crossover calculator not only capable of designing 1st order crossover as our previous post, but also support the 2nd, 3rd, and 4th crossover calculation. It is very easy to design a 3-way crossover using the tool. All you have to do is fill the form, in order to specify the design parameters, which are the type or the order of the crossover design, woover impedance, midrange impedance, tweeter impedance, low crossover frequency, high crossover frequency, and the frequency spead. Following figures show some examples of crossover design cases, which solved using the online crossover calculator.
