A high performance active crossover filter kit by KMTech Design. | |
For your information, the formula for
calculating the filtering resistor values is: R = 1 / (2 x pi x C x f) Where R = resistor value in Ohms f = Desired crossover frequency in Hertz C = 0.0000001 ***You don't need to worry about the maths! We will do all the calculations for you, just ask! |
