How To Make Your Own Lpf

[wierdguy75]

I was doing some research being bored at work one day and decided to make my own crossovers just for kicks. I know we can limit certain frequencies to a tweeter by using a uF capacitor, and to make it lower we can add an inductor to the mix, but if i just wanted to make just a LPF, so that nothing over lets say 100hz could pass, How do i achieve that? Been searching endlessly on google and various audio sights but cant seem to find exactly how to do this. Anyone have any words of wisdom?

they are failry cheap. buy one. most amps alredy have them

for low pass you need an inductor in series with the speaker that would be a 6db if you want to make the slope steeper you add a capacitor to ground after the inductor. There are certain websites that have calculators that will tell you what component values to use.

Just a chunky chunky coil It's much easier to do crossovering on line-level signals though, otherwise you have to consider the power handling and impedance matching of the crossover.
