Question on crossover simulation

ClarisysAudio · Nov 16, 2016

Hello Members,

i am trying to find a software which can simulate the crossover schematic.
I did check the values on the schematics in various calculators and they seem to check out.

From what i understand, they are two 1st order high pass filters in series + two 1st order low pass filters in series to create a real slope.

Q: Is this a bandpass filter or how do you call that?
Q: Are the crossover points at 0db or -6? (For example: 0db @ 48Hz ; -6db @96Hz)

Thanks for any help

Hi Florian,

Have you checked out LTSpice?

Hi YashN,

thanks for the tip!
I am getting there, altough i had to load a module for my Burr Brown OPA606KP.

You're on the right track.

Yes, but now i am hitting a wall. I cant simulate the high pass but maybe when i get some more free time.
I did set the source to 1V AC....

Looks like all of them all in band-pass configuration to me.

You could trying simplifying the Tweeter band-pass with just one low-pass and one high-pass and see if it works, then add the others.

Keep at it, you should reach your goals.

Hi YashN,

thanks, i got it to work

Fully 4 Way
