this measurement refers to the second type of crossover, with a different approach than the one you saw above and you can see how it has difficulties on the low range. it sounds very good, in the medium-low and high range and is well balanced, but below that deficiency is immediately noticeable.
The plot technique is looking better.
What does your bass look like if you put the mic very close to the cone and measure? Have you looked at your room effect?

move the mic closer to the woofer, I haven't tried it yet. for now I've kept levels and distances to see the differences between the two crossovers - the mic is on the X and Y axis between the tweeter and the woofer. and no room control at the moment.
Ok. When you are ready, putting the mic close (less than 1cm) will tell you the bass response without the room. You can learn what is causing your problem.

I'd rather take the yellow cones and use them to make swallows' nests.
i think i'll try a third crossover - i can already make a modification to the first one (green) - i think i can get some more low frequencies out now that i've understood how this yellow cone behaves with the various resistors and capacitors and fine tune the tweeter, based on crossover n°2 which actually sounds better. then i think i'll place an order for capacitors with values between 0.2uF and 10uf so i can try them all. if you see that the capacitor market will have a price spike you'll know it was me.

My two cents. Given that chances for a mic manufacturer to build their own electret capsules are thin, it's likely they use ready available parts and in my understanding these fall to just a few categories regarding frequency response irregularities. If one could find the exact part then the calibration file should apply. That is in my opinion of course. But I built a mic based on that and generally I'm satisfied.
Measuring known speakers, I got a rough idea about its generic frequency response.
Something like that. Then I downloaded a commercial calibration file and edited it with a text editor. Simple as that.
When loaded in ARTA it looks like this
Accuracy of this method depends on the reference used, preferably another known mic but what I did works for me.
