When it is required to set a crossover frequency of 120 Hz using speakers with an

impedance of 4 ohms.

 

 

 

 

 

Prepare commercially-available coil and capacitor with the closest ratings to the results

calculated from the formula above. The capacitor rating should be as close as possible to

331.25 (µF) and the coil rating should be as close as possible to 5.3 (mH).

2CAUTION

 

 

 

 

 

If you wish to bridge-connect a speaker, the speaker impedance must be no less than 4 ohms. Connecting a speaker with an impedance lower than 4 ohms may damage the unit.
