Hello
Yeah but the point is if you don't why bother taking them? Once you get a technique down it's not hard. You have to go through the learning curve. If you can't verify your build against your simulations you don't know what you have.

The free REW software app has a "Scope" that emulates a two channel oscilloscope and has 13 different types of signal and noise generators.
With your measurement mic using it's pink noise generator you can see (and hear) the response on it's RTA (real time analyzer) while you change crossover components, a huge help in bridging the gap from learning to knowing.
Sticking to passive, an LCR meter also really helps- hard to estimate how many inches of wire will raise or lower an inductor to the value needed, or how far off a capacitor is off from it's nameplate.

I’m jumping back into this thread because I’m also struggling to find reliable, comprehensive guides that hit the right balance.
Right now, I’m focusing on quasi-anechoic measurement techniques for an active/DSP Econowave two-way.
Here’s what I’ve found so far:
• Udemy course by Youtuber "AudioJudgement" – paid, appears to be beginner-friendly. curious if others have an opinion on his methodolgy
• Testing Loudspeakers by Joseph d’Appolito – just ordered, unsure about beginner-friendliness.
• Piecemeal advice across forums.
• Targeted tutorials (e.g. REW, MiniDSP).
What's missing is a complete start-to-finish guide on speaker measurement, especially for horns and active DSP crossovers. Happy to be proven wrong here!

Let's ask politely Harman International to provide us with a guide like that,
and in return it may be full of ads and we as community will give our best to
endorse their products in an objective fashion, that can only be topped by
our own designs. Better strike that last topping part.
Opinions?

A couple of things that might be useful.
