super,
Since you are running 3 way, maybe you would like to try to TA only the midbass. Ie. Set your midrange frequencies at a minimum of 800Hz @ 12dB. Let the midrange and tweeter play from 800Hz up. Try set the TA to zero for these 2 drivers. Then TA the midbass and see whether the imaging is acceptable to you....just my 2 sen

his setup is ok i think, time align the tweets with front pre out using the HU, this should help the most.  what are your crossover frequencies for the high, mid & sub?  i assume your HU is already set for 3 way (hi/mid/lo) and not front/rear/sub.  the a/d/s has a bandpass capable onboard crossover so thats fine to split the frequencies between midrange & midbass.

wengweng can not laa.. coz he use same output/source for Midbass & Midrange from HU.. how to set zero for Midrange & adj the TA for midbass at the same time.. if he resort amp again should be laa.. a/d/s for tweet & midrange

haha OSB, I didnt read properly....yeah midrange + midbass from 1 preout.. :-[ 

The method I said can throw away....Or can the a/d/s used to HP tweeter + bandpass for midrange ? Something like tweeter HP 6k-8k, and midrange bandpass 250-8k ? If can, then still can do resorting like OSB said.

Curious, what is the bandpass frequencies for the midbass and midrange currently ?

now...after some advice from louis......maybe try to put the tweeters and midrange higher....so that driver dash bulge not interfering the driver.....take off some polyfill from sub box....

then maybe i try swap amp.....

helix 60X2 power mid bass(coz this amp comes with individual gain)
a/d/s power tweets and midrange.

y 3 way so headache 1.....haih....

3-way memang headache one ma... :D Anyway... i was actually initially thinking you are using the a/d/s/ for the tweeters and midrange, until later only i finally understand you are using it for midrange and midbass instead, hence the earlier suggestions i made were kinda flawed about the crossover frequencies and slope.
npdang's the man, DiYMA rocks!!!

after swaping.....no more low vocal sticking on the doors....
but more hissing on jm.lab track11 and the snare dont sound like 1.....no impact....
but the midbass now is much better than before....

got some advice from built and polkman.....
but still something is lacking....
maybe take polkman advice to go with midrange on the kicks....

superglwl,

me, advice? you must be kidding...
 
the chat we had this afternoon was just an
exchange of ideas. in fact, i find that your car
set up is oledi very good. perhaps it just your
expectation - "really high". or maybe i was sitting
in middle, behind you guys.

you help more than you would know....
anyway...after 2 hours in the car....
play with driver level, the tweeters no longer hiss that much.
TA the midrange and tweets to match the driver to get that snare impact..
so far so good...
MARANTZ test disc track no 6 sounded just the way i like it....but vocal still sound a bit too thick untill muddy..
still need to get golden ears to do the crossover point right...

learn alot from louis,polkman and built in this 2 days....
thanks alot man you guys...

and yes of coz thanks built for the drink you buy me today.
