Third-order filter for passive audio crossovers.
Low-pass filter with slope of 18dB per octave.

It calculates the components values of a low pass filter for a passive audio crossovers.
Useful for two-way (or more) speakers or with separated subwoofer, the low pass is the way which supply the transducer for the reproduction of low frequencies (woofer or subwoofer).

Data input

F - Cutoff frequency:

Hz (mm)

Nominal impedance of the transducer:

Ohm
