OK, understood what you mean.I shifted the graph to visualise the required delay. Delay can come from filters on the electrical side, but also from the physical driver differences (domes curve out, but cones curve in, so their surfaces are different distances away from the mic).
No,not at all! This is why I always have the time-zero 10 kHz marker which should be "recorded" by tweeter(s) even for WO and or SW measurements.You are presuming that your woofer has no physical delay, but I am suggesting it does.
I strongly request you to first read carefully my post #493 where I clearly objectively found that SW delays in 16.0 msec against my WO+SQ+TW+ST.
(I believe very well fit for the scope of this thread on SW alignments.)
Then in mypost #504, I objectively found that my WO relatively delays 0.3 msec against SQ+TW+ST.
(I dared not to write my post on "there is no delay between SQ, TW, and ST".)
Consequently, my final time-alignment tuning for time-align to the most dalying SW;
0.00 msec (no) group delay for SWs
16.0 msec group delay for WOs
16.3 msec group delay for SQs+TWs+STs
Hope these are well understandable for you.
