Did it just happened to me or are the drivers designed like this, don’t know.
Can somebody say by own experience:
If for example at crossover point two drivers are phase coherent, then bend phase graphs absolutely parallel is not possible. OK.
How many degrees phase shift off from octave higher/lower region, is listenable/acceptable (subjective opinion).
I got some 4-5degrees off, if go octave lower or higher from crosspoint.
24db/oct I think will use.
Cross Low/Mid at 300Hz, adjusting delay 0,12ms they will be at crosspoint right (not neccessary mention the 180degree 'trick')
