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

Scheme of part of an audio crossovers, high pass 12 dB octave.

It calculates components values of an high pass filter for a passive audio crossovers.
Useful for two-way (or more) speakers (loudspeakers) or separated supertweeter, high pass filter is the way which supply the transducer for the reproduction of high frequencies called high or treble (tweeter or supertweeter).
