Im looking at adding a time allignment processor (bitone) ive never done "chemical "time allignment (only physical ta by actuall speaker location never by processor)
curious to know those who have used it if its really a benifit to tweters.
my thoughts are it is not that importsnt for high freq. as location is mainly judged by intensity a nd wave length is so short if you move your head 1 inch its out of allignment anyway..by the way tweets in a pillar mids in door.
correct me if im wrong.

in my experience, time alignment makes that most difference on the tweeters.

why, i don't know.

maybe because sound is more directional as frequency rises,
maybe becuase the majority of vocals are coming through tweeters (unless running three way)

im not sure, but if you have the means to do it, do it.

Some experts swear by TA
Some experts swear at TA
It makes a profound difference and can be a novices worst enemy to good sound, yet in the right hands TA can do quite a bit to improve the listening experience

im clear that i must get ta to get the sound i want and i know mids and bass with out a doubt will benifit big so without question im getting the ta.
what i really want to know is ..as im runnig the components passive off a 2 channel amp is if it would make enough difference to go active and 4 channel on the comps and align each seperate or if i should just keep it simple , keep it passive and align each side...
as noted tweeters are highly directional but also intensity dependant.

Above 3khz TA becomes not so important and intensity becomes the defining factor. Under 3khz, it's all about time arrival so TA is mucho important there.

So basically i am correct and should just do the ta and leave the comps passive and not overcomplicate things then.
not theat active crossovers dont have advantages, but i like simple less potential for errors..

The tweeters are essential for precise imaging (determining where the recorded instruments are located) I have never heard the comment AAAAAAAAAA said before and would have to research it prior to trying to support or refute it.

TA is kind of a package deal the whole point is to put the entire frequency spectrum in the same time domain (but it really is just an approximation). For instance in a 2 way system with mid-bass in the kick panels :The highs in the drivers A pillar (12 inches from your head) are typically delayed a bit so the sound arrives at the same time as the mid and woofer (4 feet from your head). now the passenger side is different as the tweeter is about 4 feet away (like the driver side mid-bass) and the passenger side mid-bass may be the farthest driver from the drivers ear in the car (even farther than the woofer).

Unless your mids and tweets are very close together, the T/A will not work properly in a passive set up, as both the mid and tweet will be delayed the same amount and the farther apart they are, the more time distortion will take place defeating the purpose. To properly do T/A, you need a separate channel for each speaker. Tweets are less affected than mids by T/A in my opinion, but still enough to affect performance.

Get the BitOne (or whatever TA box you choose) - regardless the benefits of it properly setup with outway any nuances etc that may come of what it does. Again - if it is PROPERLY setup.
