Coil (L):
Passes low frequencies and blocks high frequencies. (Low pass)
Capacitor (C):
Passes high frequencies and blocks low frequencies. (High pass)

Example:
When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms.
Prepare
2CAUTION
•If you wish to
•Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer.
•Ensure that the withstand voltage and current ratings of the capacitors (C) and coils
(L) are sufficient.
