Just having a bit of trouble understanding time alignment with Active speakers using REW.
I have read much information and even a bunch of threads on the overall matter. It seems the general wisdom is to align the impulse. But with a 3way active speaker, the impulse is obviously very, very different, the tweeter, sharp, the midrange less so, and the LF is just a long wave.
So I have a large modular 3-way speaker, in which I placed mic at listening position for the time alignment.
Now in my messing around, it seems that the REW estimate for the delay is not quite on point and totally reliable to use, its close, but if you follow the estimate and align only based on that, the impulse and step wont match properly.
So, something I tried to do, keep the same crossover slopes in the final design, but change the LF and Mid speakers to fall off at 6k each so they produce a similar/better Impulse and step, and then align those... Is that the right thing to do?
Also, if I do that, I can never get impulse and step both perfectly lined up at the same time even when talking about a 6k rolloff for the task.
Yesterday in my latest efforts I settled on aligning the step response so the peaks all lined up in the initial step, the impulse was relatively close but not quite matching.
Which one should take priority??
p.s. the mid and lf woofer impulses in the project are inverted due to inverse measurements, its the tweeter that will be inverted in the speaker, not the mid and LF... I just did that so the step pointed up...
Any feedback, help welcome.
