kool... thanks guys... i might see you at the next one, if its in reach ... and my systems all fixed, i nwo have FREEKIN NOISE!!!

i installed a new battery and put new terminals in and what do i get, friken static through the subs lol

[Pulse-R]

maybe check the new connections, and make sure the wire from the battery negative to the chassis is good.

oh it is

ok i am in the pro audio game and i dont really understand what u r talking about with staging hearing where each person is i dont belive that to be correct with a band each peace of equipment is amped and then gets mixed togethor and out of the front speakers so where does this staging come from

"staging land"..... It costs $24 a month and is available through "U tunes"....

BTW, I'm in the Pro audio game too... I'm up to level 16, but I can't get past the end level boss "Rear fill". Got any hints on defeating him?

use the ultra fading control on ure uber HU to own that n00b

[KickerCat]

Ben - I've got the cheat codes - you playing on xbox or PS2?

I'm a bit worried about someone in the 'pro audio game' that doesn't know what staging is too....

[mazda626]

maybe he has the beta version

THANK GOD!!!! I almost thought that my sarcasm would be lost on u guys.....

Now... With staging... Some "audiophiles" may call it myth, but it DOES EXIST....

I had an (old) friend who used to work at Strathfield doing installs back in the day (how long have stratties been running for? ) but anyway, he considered himself to be an audiophile and taught me that staging was having all the speakers perfectly setup so you couldn't tell where the speakers were, or where exactly the sound was coming from. Basically, to make the image come from everywhere, but nowhere in particular, so the sound surrounded you.... along those lines anyway.

Was he completely wrong or was he refering to something a little different?

[~thematt~]

Not wrong, but not all right.

You shouldnt hear the speakers, they should be invisible, but the sound itself should seem to come from one spot. This is the image.

And a tip for you. T/A is almost useless on Tweeters, and higher end midrange. Use gain (independant L/R works wonders here ) to solidify that image. T/A is brilliant for subbass and midbass integration though.

I'd disagree there.
TA on tweeters is useful for increasing the depth of a centre image - once you get the levels and EQ right.

I say EQ because any imbalance (more than 0.25dB) will cause some 'steering' of the image - most noticeable when you get the image razor sharp. If you have a blurry centre image (lacks focus) then TA or EQ won't help much.

[~thematt~]

I agree with the EQ bit, but Ill try and remember the bits from my noise propagation textbook...... there is also a thread from Abmolech a while back which breifly mentions it. Quite interesting.

Basically, intensity differences (source wave doesnt decrease in intensity) dont really exist in the near field, and the brain uses time delay to determine distance and position. The time taken for one ear to receive and process is weighed up against the time taken for the other ear, and an image is projected from there.

However, Tweeters are normally located in the far field, and therefore outside this time delay zone. In the far field, its intensity difference that the brain uses, otherwise known as interaural intensity difference (sp?). Basically, if the tweeters are on different path lengths (as they always are in the car), then the brain will use intensity differences to locate image. If you have a tweeter in the kicks, changing the gain from left to right (or independant EQ might work too - never tried it) will change the intensity of the tweeters relative to each other and allow sharper image.

If your tweeters are on the sails though, as mine are, then its kind of a mixture. TA for near field, Gain for far field. Hard to fix an image, but not impossible.

TA after independant gain adjustment might work to sharpen, never really tried it. But TA instead of, is really swimming against the current. You should be using the aural waves in your favour, not fighting against them.

[Pulse-R]

the point I was making - unless your car is (almost)exactly symmetrical from the tweeters, radiating out toward the listening position, then there will be some difference in the frequency response of the two (i.e. steering wheel if it's in the path, or near the path). This needs to be corrected to re-create the sharpest possible image.
I have found that making changes of 0.25dB to overall level, or +/- 0.5dB corrections on 1/3oct.EQ will improve (or better shape) the focus of the centre (and outer stage) images.
