With a CSS compliant browser like NS 7, Mozilla, IE 5, IE 6, or Opera 7, the above chart will plot the frequency and reactance values of the calculators.
Enter: desired frequency:
Hz., desired reactance:
ohms
(eg: driver impedance for first order crossover, sqrt(2) x driver impedance for second order crossover)
