Hi, can anyone give me an eye on these crossover diagrams i found on internet, which one is better to choose by your opinion?
Till now i have used just with one capacitor around 3 uF and active filter, but now i want to keep going these speakers with tube amp Quoad II and Philips cd880 in direct mode. Boxes are 110l with vent. BM12CXA - Google Photos

To be honest, without a bit more info it's impossible to say.
P Audio don't seem to have provided impedance curves for this driver (at least, not on the only spec sheet I could find) so assessing crossover networks is a bit futile.
Do you have a measurement setup with which you could measure the impedance curve of each part of the driver, and the on- and off-axis frequency response curves by any chance?
That would make a big difference.
Just because I wanted to have a play around in VituixCad, I did trace the manufacturer's frequency response curve and model the networks anyway, you can see the results of that below.
However, without the impedance curves, none of these look brilliant. They also assume your in-box freq response is the same as the manufacturer's, which isn't likely to be valid, and they don't give any indication of off-axis behaviour.
FWIW,
David.

Thank you! Actually I can, I just need to visit to my parents, my father has an oscilloscope and a signal generator, i will try to measure and make impedance curves by frequency response. It shouldn't be too hard, but i will get a chance just next week 🙂
