Crossover and phase importance

[ThatSoundsGood]

Crossover simulation based on actual polar measurements of the drivers in a prototype cabinet

Is there smoothing applied? Smoothing can make the null look less deep. If this is the null out of phase and the summation of the two curves is 6db when they are in phase then it would be good.

The vituixcad '6-pack' image in the first post is the the same crossover. Frequency responses were smoothed to 1/48th when exported from REW to vituixcad. This last image is the same circuit but now with reversed polarity on the tweeter to show the null.

For example of crossover null, look at designs of Heismann.

This is the result with the tweeter inverted. I'm not sure how deep the null is supposed to be. To me it looks pretty deep with -7.3dB

This is the expected result and it shows the null perfectly. There it is, you've seen it, you can now set the polarity straight again and get on with it

Actually improved it quite a bit

And with the tweeter polarity inverted:

Well done, you learned to give the xover a fitting frequency and attenuation for the drivers.
Here we go.
