If we use a 8th order Butterworth high pass filter for subwoofer, and 4th order high pass filter LR type for upper speaker, more phase lines will appear for subs than upper speaker. Please guide me how to align at that time.
You mentioned no delay time reference on sub measurement. While debating on colors you never mentioned if you need find a delay time reference on the mains?? 😢
You have delay the channel that supplies the speakers that are physically closer to the audience. If your subs are further from the audience than your main LR, you can't delay them in order to time align the PA.
@@user-uh2cr9so8l Yes, it's all about alignment and avoiding a loss of SPL due to cancellation (or, in other words: summation). And as soon as it's clear how that works, it will also be clear why my initial statement about what channel of the PA (subs or mains LR) needs to be delayed is true. I'm happy to elaborate further, if necessary. :)
I think you can do either, as long you can achieve the phase alignment/ summation. A friend who does bass heavy music told me the bass is the "base", and so that is 0 delay, and you match your tops to the subs.
@@user-uh2cr9so8l subs are a weird case because there’s no one point in the room to delay from because mains and subs will arrive at a different time for everyone, but generally for ground subs the subs are gonna hit before the mains so if you do any delaying that should happen on the subs. The flown mains are always farther for people standing on the ground, just a matter of how much farther But for front fills and stuff it’s much easier, just find the zone where the two speakers overlap and delay the fills until they’re coherent. Again there is a right answer - a certain amount of delay that makes things line up coherently, and you can massage that number to achieve the results you want or focus attention on the fills or whatever You can’t just arbitrarily pick one and delay the other to it because your subs are always hitting before your tops so no amount of delaying tops can bring them into phase - 360 degrees out of phase is not in phase
Why did you not use the delay insert feature ..so first Postion the delay of the main stack to the mic and then line up the sub to it
I got a tad bit distracted during the color changes but great video!!

Why do you only do the right speaker? Wouldnt you take three traces left, center, and right?

I thought you had to delay the subs since they are physically closer and would require less time delay than the tops. ?
In this case the subs are upstage of the tops.
@@UncleWalter1 what if the subs were downstage or in front of the stage, would you still measure the subs before the tops?
you supposed to delay the sub ... right? or any new technology?

@@prospekt1909 You dont have to though, right? All that matters is the achievement of summation and phase alignment?

An all in one 3 way cabinet, still need to be time aligned?
They would work better if they were yes
which one should we set a delay on our system?? the sub or tops??
i stiil don't understand
