Spectrogram like in post #11 i have for all separate drivers without filters and with filters. Only frequency response. Phase response I don't.

Can they be lifted out of the noise? - It is need to smooth they?

Later, can they be done anechoically? - Yes, but how do this right? Should all other speakers work during the measurement of one speaker, or should the others be turned off?

With phase you can understand how the drivers work together. You can see how the filters are not helping.

Also make them louder if possible. Make a measurement with the amp muted. Use this information to get each driver (measured on its own) away from the noise. If you go too loud the response will top out and clip.
