Romy,  I tried non-symmetric crossovers (freq and slopes different for channels) but had to go back to symmetric because the phase response sounded very wrong to my ears. I learned that I could get used to a bad frequency response but I could not get used to a non-linear phase response.     I think the crossover you are proposing will introduce this "step" in the phase response.   Is there anything bad about using a tubed bass trap in your room?  

I do not use tubed bass trap as I do not like the sound they produce.  To have any more or less sensitive absorption at 50Hz you knee to put a lot of trap in the room and they shorten reverberation time at upper bass very aggressively as they have much higher absorption rate at 300-500Hz. 
 
Regarding the phase response. Yes, I very much agree with you and I am for years a curator of the idea that we do not hear amplitude but hear only phase. As I will be introducing a very narrow bandwidth channel I am wondering myself how to organize the things phase-wise and the most important how to calibrate the phase performance. I have my problem with pulse response and with LMS analyses. So, I need to find a matrix how I will be align the new midbass channel. I am not sure if I need to do it by pure arrival time minus reflection or I need to factor in the reverberations. I need to experiment and to listen it.
