I personally follow the VituixCAD guidelines of measuring each driver's on it's own axis and entering y-offset. But I've seen many people measure on the tweeter axis and then keep the offsets zero.
I'm pretty sure it only makes a minor difference and its okay the way he has it. Hopefully someone who knows for sure can chime in.
The measurements on the tweeter than mid were taken at 670mm while the woofer measurment was taken at 380mm. I decided to follow the vituix guide this time and dropped the mic for the woofer measurment.
The tweeter and mid were taken right in the mid of each other per the guide at 670mm height from base of cabinet. The woofer was taken at it own height of 380mm
Forgot to tell you i switched it up. Tweeter and mid taken at 675 and woofer taken at 380mm
Just another trick we use regularly in the shop here (paid projects): if you need a 30 watt 6 ohm resistor but that is expensive you can just use 3x 10 watt 2 ohm resistors inline. Same result. You'll probably want to use 1%ers here though as you have multiplied the off spec by 3 times using three of them. Higher wattage resistor can get expensive
What is this thing? I haven't seen this form of filter before.

I will try entering this in but I think that tweeter is gonna distort at higher wattages since its leaking really low into the frequency band
Please note that I shifted all levels up by 40dB for better viewing in my spreadsheet, hence the average level ~100dB, and the scale is different from the VituixCAD plots, I show all the way down to 0 so I can plot impedance in the same graph. The tweeter is down by 50dB @ 1kHz, I think it will be ok.
270 nF plus 5.6 ohms together with 1 mH form notch filter at about 10 kHz, in order to clean midrange high output mess there.
Edit: Further, 1 mH plus 8.2 uF form second order low-pass filter.
A few values are wrong and you didn't include the L-pad for the mid driver, please double check

To make it sure I understand you right: you measured both tweeter and mid (separately) at the same point/axis which is in the middle between the two? That is wrong! This is the correct procedure: measure at tweeter height, than drop the mike at the mid axis and then measure the mid, and on the end - drop the mike again at the woofer axis height and measure the woofer.
Until you measure it again, we have to work with these "Y" values:
Ytweeter = 0
Ymid = 0
Ywoofer = 380-670 = -290 mm (or 380-675 = -295 mm). Which one is correct - 670 or 675 mm?

675.
The guide literally said I could take it at the same height for both of them. I wanted to minimize me accidentally angling the mic between measurements
I see that, that's not good. These will be listened to 90% of the time at 15 degrees off axis. Any way to fix this or is it just the nature of the drivers at the distance I have them apart?
I'll your new one. Yeah, vituixcad is pretty easy to use. Understanding the tools is a little more challenging but worth learning I think
I think something isn't loaded right. Did you load all the on/off axis measurements into the driver tab? You can load all the different angled measurements in there

I think I may have screwed up and given you guys some wrong files. I just ran through everybody's and none of them translate with the loaded measurements. I am going to move this XO into a new thread. I will post where that thread is in a minute.
I will make a new zip file with all the measurements and triple check that I have loaded up the right ones.
I apologize, I do very much appreciate the help I am being given and feel bad that I have wasted some of your time.
