I was hoping that was the case. Thanks!
I matched up all the XO components as best I could, and unwound any coils that didn't match until they did match, so I was expecting the sweeps to be identical. Good to know that slight differences are ok.
Here is the center speaker which uses different components. I find it interesting how the shapes of the peaks and the space between the peaks are different. I can shift the peaks around and alter the height of the peaks by changing the ports. But I'm not really sure what these peaks should look like in an ideal situation. Should the first peak be the higher one, or the second? Or should they ideally be the same height?
Which impedance measurement is better, the blue/red from post 1 or this green one? And why? Or are they both perfectly fine just different?

Don't worry about them, they all are fine. The twin peaks only are the same height in certain tuning options. And since you also would have to take into account the room response the variations your plots show are of no real interest.
Now what would be of interest is to repeat the measurements with high frequency resolution. That way you could check for resonances in the system.

I'd use LIMP (part of the ARTA suite) by Ivo Mateljan. This app has slow (frequency) sweep and very small step settings.
Indeed.
There is a thing in industry called "tolerance", which is basically in everything manufactured, measured in percentages.
Cheaper products have a wider range, naturally, as opposed to "higher end" ones.
Some people, for whatever reason, become overly concerned about slight differences.
