vegatron thankyou first for offering to help me out...
** no probs .. .I only got 2 sushis worth to offer hehe! :D
a quick run through of my setup...
HU:Pioneer 5750
Prosessor: Alpine H701 and the controller
Tweets: Scans D3004-660000
mid:Morel CDM54
Woofer:DLS Nobelium 8
Sub: Hellix Dark Blue12"
Amps: Helix H400(2 units)
** interesting mix.... I love rojak
1. about the passives... they are the two way passives... i mean 5kHz for high-pass and low-pass... my connecttion was high pass for the tweets and low pass for the mid-ranges... and all these are high-passed again at somewhere 500Hz to 600Hz... so its like my mid are band-passed from 500Hz to 5kHz and the tweets are high-passed at 5kHz... hope this one is clear enough...
** Ah so desuka. Vellie clear now.
2. i crossed the 8" at 520Hz is because i was told by the ori owner of the Morel tht the mid are only good lowest till 800Hz and highest around 5kHz... so i dun dare to go too low for those... and i crossed the morel high-pass at 500Hz and lower than tht i run them through the 8" which are band-passed at 520Hz low-pass and 60Hz high pass...
** Ok I think I got you, you've bandpassed them 60-520hz ok that shd be about fine...
3. sorry for the typo.. didnt reliaze it... anyway... why 12Khz? i was randomly crossing it... cuz i dun feel any difference from the tweets and the mid on which ever cross point... mayb i am tone deaf or the setup was completely wrong... where do you think i should cross them?
** u got a great pair of tweeters , and I believe they can easily play down to 3khz or even 2.5khz.
** wokay 1st things 1st. Have you phase checked all your drivers (tweets, mids , woofers & subs). If you haven't find a good installer who has a good phase checker. Or borrow a phase checker, make sure all are on phase.
Xover settings:
1. high pass your tweeters about 3khz.
2. Bandpass your mids 500 hz to 3khz shd be about right. You might want to try moving the high pass down to maybe 400hz just to play around a bit.
3. Bandpass your 8" woofers 60hz to 500hz or 400hz also the same just to play around with it a bit.
4. Low pass your subwoofer 60hz
Next, don't worry about the staging yet. Are your gains O-scoped? do you know where are the clipping points? If you don't know, I suggest you also send your car in to O-scope the amps, find out at which point they clip. Clip means distort. Which is not audible to an untrained ear, best to use an O-scope to see it.
Next, play around with the gains (assuming u know where are the clipping points), to get a good balanced output between all your drivers, meaning no driver is over powering the other. Means like your morels are over powering the tweets, or tweets are so loud it's killing the music or your 8" is smothering your mids.
Last, to get centre stage..... find an ICE sifu to do placement and fine tuning till u get centre stage :D:D:D sorry... this one is so difficult I can't describe how to get centre stage. It depends on car, speakers, amps, eq, etc etc etc. The combinations are limitless .... like finding a needle in a hay stack.
I told u I only got 2 sushi's worth rite? hehehehe!
Later!
