*You may change the subwoofer satellite crossover frequency by using the
Inductor and Capacitor values calculated with the following formulas:
30,000
High-Pass (Satellite Crossover): Desired crossover Frequency in Hz = New Capacitor Value in ?F
620
Low-Pass(Subwoofer Crossover): Desired crossover Frequency in Hz = New Inductor Value in mH
