Let's talk about time alignment!

[chad]

Maybe I'm missing something......when I set my t/a using measurements, my tonality goes to shit.....I thought due to phasing errors.....doesn't sound natural, actually quite terrible. It was only through experimentation, moving up and down through my t/a adjustments that I've found settings that both sound natural and stage well. This was a long process, but the results absolutely blow the physical measurements settings out of the water, halfway across the country to the fucking desert.......

How are you measuring?

Do you raise the sub xover to an overlap with mids?

When you cross any driver the slope depicts how fast it rolls off, the type (bessel, L/R, Butterworth) depicts how it acts AT the crossover frequency and how it "knees off"...

So if you cross your mids at 80 and your sub at 80 then you have drivers playing the same frequencies...

Wait...
If you set a LPF @ 80hz, then 80hz is just where it hits the actual slope selected. But the particular "knee off" you speak of will actually start a few hz higher than 80.

yup, 80 is the -3 point.

Next thing someone is going to tell you is how delaying the whole thing makes it bleed unicorn piss. When in reality the only difference will be the difference on how long it takes the time to stop when you hit pause.

I can delay the whole thing by several minutes just be waiting to hit the play button

But that's analog delay....

Only us old farts know that that once existed.

[PaulD]

But if I tap the play button with my finger (digit), wouldn't that make it digital ?

[chad]

Nah, analog sounds better... it's more audiophool.

I understand an xover is a slope, not a brick wall. My mids and subs are gapped. (subs lp 63 on 24, mids hp 80 on 24) Yesterday at lunch I thought about this thread and bumped my sub up to 80. Didn't care for it with just that(subs are delayed 37.5" in normal tune). Being the audio idiot I am, felt I needed a little more info (and time) before proceeding. I'm intrigued by the concept and open to learning more.

yup, 80 is the -3 point.

Depending on what type of shelf you choose correct?

I thought they always named it by the -3 point, regardless of slope. If that's the case, the 'knee' would have to move with the slope. Farther away from the -3 point for shallow slopes, closer for steeper slopes.
