We all know that we have to avoid saturating coils but I don't really know why.
Does the impedance go up, down, does it distort the signal and if yes in which way?
Basically what I would like to know is: What does it sound like?

The inductor's impedance goes way down, but the effect on the sound depends on the crossover circuit.

Just ran across this recently, maybe it will shed some light on the subject.

Thanks guys!
I don't usually do passive crossovers but a while ago I wondered what actually happens in a saturated crossover coil and after wasting an afternoon searching I couldn't find anything with a practical explanation much beyond 'it's bad' and 'best avoided' I thought this is the place to satisfy my curiosity.
And it is! 🙂

REW is excellent for all-electric measurements (including those rarely posted measurements called "distortion").
For example, you could simply do a Real Time Analysis (RTA) and see what odd frequencies are showing up.
You might need to locate a cable that is RCA-to-alligator clips, unless you already own a bunch. And you need to keep the signal to the ADC under a volt using a voltage divider.
BTW, you should never do acoustic measurements until you've verified that the electric signal is healthy. Any time I've checked my MacBook, the noise, THD, and freq response have been exceptional. And ancient cheap DAC ($4 from Salvation Army store). And my Behringer DCX2496 DSP. And USB to SPDIF converter. And 35 yr old amps. And all of them lined up in series too.
