A. Satellite/Subwoofer
*You may change the subwoofer satelite crossover frequency by using the Inductor and Capacitor values calculated
with the following formulas:
High Pass (Satelite Crossover): = New Capacitor Value in µF
30,000
Desired crossover Frequency in Hz
Low Pass (Subwoofer Crossover): = New Inductor Value in mH
620
Desired crossover Frequency in Hz
