I'm thinking of using this approach to avoid buying something that I'll only use once: https://audiojudgement.com/loudspeaker-impedance-measurement/Did you have a chance do take any measurements? Even simple impedance sweep can be very useful. If by chance any connection in the crossover is misplaced or missing it creates evident change in the impedance graph.
Build it, it is EASY. Here are step-by-step instructions (maybe annoyingly long) on building a jig and measuring impedance in REW.I'm thinking of using this approach to avoid buying something that I'll only use once: https://audiojudgement.com/loudspeaker-impedance-measurement/
Any advice or comments?

I appreciate the responses, but your objectives seem different from mine. You both seem heavily involved in DIY speakers; I expect the two Mechano23's to be the only speakers I will ever build.
So, to clarify: My only purpose in measuring impedance is to confirm that I have wired two Mechano23 crossovers properly. My cost in using Audio Judgement's approach is about $6.
The DATS is $125, the audio interfaces I could easily find were that or more.
Will the simple and cheap Audio Judgement approach confirm my wiring?
Honestly it seems like false economy to me.I'm thinking of using this approach to avoid buying something that I'll only use once: https://audiojudgement.com/loudspeaker-impedance-measurement/

Download a phone app (RTA?) and measure the speaker at 1m or 2m with the xo installed. If the xo is wrong it will probably be clear in the measurement.... I'll read more on REW's measurements, but I expect that I'll revert to visual inspections. After all, it's a simple circuit and I'll lay it out the same way. What could go wrong?
See links from sig:@XMechanik You have any ideas about designing more speakers? Or maybe you already have other designs. Clearly you know what you are doing!
If we take the author's estimate of 30 minutes per impedance sweep as accurate
I was referring to the time estimate given by the author of the manual multimeter technique referenced above. The DATS box I used takes maybe 2-6 seconds total to do an impedance sweep.Am I hearing that right, 30 minutes per sweep?
