Let us know what crossover frequencies you need and we will get as close as possible by changing 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! | |
