Starting from what THD you consider them unacceptable?

Yes! Impressive. Very fast.

I'll check tomorrow. Currently I have -40 dB 2'nd order from tweeters designed to be tweeters. And more than 30 periods of ringing around 5 kHz down to 30 dB level.

Trying other tweeters I've found similar "2 horns" so they belong to Behringer microphone I used to measure.
Speakers sound brilliantly (16 per side in line arrays).
