	A high performance active crossover filter by  KMTech Design. DIY PCB - YOU WILL NEED SOLDERING SKILLS.
	Let us know what crossover frequencies you need  and we will get as close as possible by suggesting resistor values.
	For your information, the formula for  calculating the filtering resistor values is: R = 1 / (8.89 x C x f) Where R = resistor value in Ohms f = Desired crossover frequency in Hertz C = 0.000000033 ***You don't need to worry about the maths! We will do all the  calculations for you! Happy to help!
	Please note there is no enclosure included with  this product, it is as shown in the first listing photo. Components You Will Need: 3 x NE5532 low noise dual audio grade op-amps. 3 x 8-way IC sockets. 6 x PCB mount RCA sockets. 1 x 3 way 5mm terminal block. 4 x 100k resistor (all resistors 1/4 Watt, metal film 1%). 2 x 1k resistor. 2 x 100k resistor. 10 x 20k resistor (for filtering, can supply different values depending on required crossover frequency). 4 x 100 ohm resistor. 3 x 100nF ceramic capacitor. 2 x 47uF electrolytic capacitors 10 x 33nF polyester capacitor.
