Sorry, replace previous mdat by this one , please.

Thank four your answer , i I breathe better :) Measurements with your delays and my proposal.

Sorry , but post-43 measurements are without delay and no xo ( delays setting in the DSP are all to 0 ms) . In post-41 it's the same same measurements ( delay setup = 0 ms) but xo are on.

Sorry, but I can't follow your reasoning, I'm lost.:frown: What do you mean by this ? :ponder: Ultimately , I think i will keep my current delays even if the phase curve is not as good as yours because i am not able to reproduce your reasoning. Sorry, thank you again for your help.

Something is wrong in my conclusion, i am not able to reproduce your SPL :ponder:

So , if i understand well , the setup delays in my DSP must be : Br Jacky

Hello, Thank you very much for your detailed and very informative response for me. Yes, REW measurements have been made with FIR EQ ON. I didn't try to make REW alignment with FIR EQ OFF. So , you will find attached file with FIR EQ off , the sweep measurement is only limited by REW...

Hello, Could you examine my alignment problem please ? Br jacky

Hello, In the Alignment tool , i can open a "Show phase trace window" (see attached picture). Which are the phase curves displayed ? ( i suppose that are loudspeaker phase , minimum phase , and excess phase) : green curve , black curve , purple curve ? Br jacky

True , so absolute delays are :

Hello, If the usage of REW is more familiar for me now , thanks to you , but your experience is needed to solve the following problem : - delay between sub and bass is 2.46ms , i must delay bass loudspeaker of this value. - delay between bass and medium is 1.84 ms , i must also delay bass...

If i do that, SPL , Impulse, GD curves are the same but phase curve is different :ponder:

Thank you very much for your help. :)

Some more questions : - what is AT process (#27) => Alignment Tool? - in the Alignment Tool , when i have a negative delay proposal , what is the meaning ? For exemple , in the #27 post, your calculation give a delay of 3.21 ms on the 1-ms-bm-110-375 speaker (Low medium), so i can setup...

Thank you very mutch for this explanation. With IR Window option , i can obtain the same result on the SPL and phase curves than the "Add frequency dependent window" when i reduce the "Left window (ms)" and "Right Window(ms)" values. Could you give me some explanations or a link to understand...
