Capacitors for low pass crossover

j-dub dub Bronze Member Username: Jdub_dub Post Number: 50 Registered: Nov-04	Posted on Sunday, April 30, 2006 - 05:36 GMT i noticed that most of the tutorials on building crossovers show that you need to use an inductor in series with the speaker to obtain a low pass network. isnt it possible to use a capacitor in parallel with the speaker to get the same result? i forgot how to make those bode plots and how to generate the equations for the filters. and one other thing, how does the phase shift from 1st, 2nd, and 3rd order networks? for some reason i thought that 2nd order networks flip it 180 degrees, but the first order varies with frequency. is this right?
