Default Compression driver polarity by brand

I had some trouble with a crossover between JBL2445 and Beyma CP385/ND. When connected in phase per terminal color, there was a notch. Inverting the tweeter helped. So I suspected Beyma, that it is inverted. Later I found out, that it was the JBL and that I have used it with opposite phase until now. Which kind of explains some of the things I saw and could not understand.

I thought JBL was the only one, but I saw a datasheet where DAS Audio M50 says that positive voltage at the black terminal moves the diaphragm towards the phase plug.

Could we list the brands with their polarity here? And how can I find the real polarity of the CD?
