Phase response questions

[WrineX]

hi, have a question i bought a set of Translator reference , its a dutch brand with only dynaudio drivers. the concept of this speaker is the use of only 6dB octaaf filters and a q factor of 0.5.

first i noticed that i did not have a strong staging of vocals, it feeled like it whas outside the speakers and not in the midlle, thats why i started measuring . when measuring the seperate units up close i noticed that one of the speakers mid dome had a wider responde then the other also the fase behaviour whas completely diferent. so i switched positive and negative on the dome that had a dip between crossover points. well now i measure the speaker at a distance of 50 cm and i thought the phase response of the bass driver whas a bit strange it goes down to minus 180 degree and then come back from the top sene in picture Old. so i changed the positive and negative and now the response look like picture new. is this correct >? or to me it looks straighter but there is this strange peak 250 hertz.



anybody has a clue because all the slopes shoud be 6dB octaaf and therefor pretty damn straight in phase response.


must say its a four way system so for me its dificult to measure.
the dynaudio units i cant see wich pole is wich no indication is this normal ? or do they have there own way of saying wich one is wich.... and also the kabel used has no indication so its really shitty.


this is the system

superhigh: 21mm dome - Dynaudio D21

hope somebody know something about phase response and measurements


bythe way this laptop has pretty bad soundcard , for somereason it wont measure above 7K
