Time Alignment

[scarysoul 10+ year member]

I have the pioneer P80 (880)...

1) i have the tweeter at A-pillar and the woofer at stock... so which one should i measure? distance from the tweeter or distance from the woofer?

2) do you also key in the distance for the subwoofer or just leave it at zero?

use the auto time aligment setting on the deck.

you should actually t/a both the left tweeter and the left mid. do it until you get the center image you like.

on that deck can you do each speaker (mid, tweet), or is it just left/right.

but just tweek it untill it sounds best to you.

i did not do any t/a on my woofer. and i really dont need to.

Typically, the correct proceedure is to delay the high to the mid and then both of them to the sub.

You're not supposed to delay low end freqs.

i did able to make the voice to sound centered (well, to perfectly centered though, but close), but when i'm planing hotel california, i can't seem to able to make the guitar sound to go up to eye level, i feel like the sound was around the hip or leg level...

I delayed both my mid and tweet on the left side till it sounded like I was in the middle. also turned down the dbs a little on the left.

That is not a time allignment issue. It a low stock mounting location issue. Honestly you are out of luck trying to change that if you stay in the stock locations.

This is a gross oversimplfication. You don't delay the subs only because they are the furthest from you, typically. Pitch plays no role in determining what to delay.

Correct, pitch does not play any roll.

But I didn't say anything about pitch.

You don't delay the subs not because they are farthest away from you, but because lowend is to hard to delay. It's wavelegnths are longer and spread farther making it harder to control and sync to the mids and highs. So why go the hard route when you can just delay the highs to the mids and then both to the sub.

It is role, not roll. Grammar ninja ATTACK. Just kidding - typos happen.

Yes, you did. When you say "lowend" you mean the speakers playing the low frequencies. Pitch is the perceived frequency of a sound.

You don't delay the subs not because they are farthest away from you, but because lowend is to hard to delay. It's wavelegnths are longer and spread farther making it harder to control and sync to the mids and highs. So why go the hard route when you can just delay the highs to the mids and then both to the sub.

So if you were sitting right next to your sub and your mids and tweets were 10 feet away, you wouldn't delay your sub?

The speed of sound on Earth through air is the same no matter what the frequency is. How much to delay a certain speaker should soley be a function of how far it is from you and the other speakers.

so if i change to 3-way and put the woofer in stock and midrange much further above, i will somehow be able to get the music more to a higher level?

It is very important to apply TA to the midbass region (80-700HZ). Above that, amplitude differences has greater effect than time.

So: TA for your mids and Eq youe tweets.
