*You may change the subwoofer satelite crossover frequency by using the Inductor and Capacitor values calculated

with the following formulas:	30,000
High Pass (Satelite Crossover):		= New Capacitor Value in ∝F
	Desired crossover Frequency in Hz
Low Pass (Subwoofer Crossover):	620	= New Inductor Value in mH
	Desired crossover Frequency in Hz
