(Low pass)Capacitor (C): Passes high frequencies and blocks lowfrequencies. (High pass)Crossover FrequencyFrequency159000C= (μF)fc x R159 x RL= (mH)fcfc=Cut of Frequency (Hz)R=Speaker Impedance (Ω)●Example:When it is required to set a crossover frequency of 120 Hz using speakers with animpedance of 4 ohms.Prepare commercially-available coil and capacitor with the closest ratings to the resultscalculated 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).• 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.• Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure todo 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) aresufficient.2CAUTION
