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!
Please note there is no enclosure included with  this product, it is as shown in the first listing photo.
