my favourite centre image tuning song: Lara Fabian - I Guess I Loved You

anyway... IASCA imaging and staging tracks and Sheffeld Labs recording for further minor tuning...

btw... not always TA is the answer... for some people(including me) after TA they dun like the narrow staging... but some people dun mind... so listen to setup with TA and non TA before you decide on the HU...

cheers...

i prefer no TA at all.....sounds unnatural with TA

may i suggest Clarion HX-D2 if u wanna do TA. its better than alpine 9887.

SQ also better.

At this point, Alpine F1 is my vote. kekekekeke

Agree. It sounds unnatural & reduce in tonality. I was being fade up that i cant get the centre staging & play aroung wiht the TA, but now ignore TA setting. But somehow a sifu being advise me to increase the individual gain of the amp. By increase the right gain of the speaker...never tried it but any idea of it?

first of all...it depends on ur amp whether got individual gain for each of the driver...esp active setup

then have to perform level matching first.....u cant get accurate imaging if ur tweeters r over powering the mids in loudness

depends active or passive

but all depends on speaker frequency response too

Before setting the HPF of your tweeters, it is very important to find out the FR.
Tune them too low will risk the tweeters's VC being damaged.

And before you come, pls make sure your speaker/amp connections:
for example channel 1 to left mid, channel 2 to right mid, channel 3 to left tweeter and channel 4 to right tweeter.
This is necessary if you have a phase problem and will make phase change for any speaker easier, instead of wasting time doing trial and error work.
I will do phase check everytime before fine tuning.
