new tweeter placement
I am looking to and a new super tweeter to my system for better staging
I have 2 possible locations
(1) custom pod 45 deg on the front doors (you have to know the inside of the celica to under stand better,just above the stock tweet-beside the side mirror)
(2) 2" from the front windshield, on the dash pointed towards the windshield
new tweet-- ht 20r-hertz
front
1"1/8-tweet-hertz -space1
6.5 -mid-rf-t1 power series

if you face them right at you, then you get one side bias even with time alignment. try to avoid that... a good rule of thumb is aiming for the centre dome light in the car... now this is just a starting point. you must adjust accordingly.

.... OK
The windshield is either your best friend or your worst enemy, either use it (and overcome the issues that the windshield causes) or avoid it (which the cramped quarters of a car makes difficult).
A one time IASCA winner used a 'super' tweeter located next to the driver and passengers head reflecting off the glass to improve HF extension and improve imaging/ depth. I do not think that would produce increased accuracy but it could improve the 'ambiance' and 'staging' or perception of depth.
I was never fond of super tweeters until... at CES 2004 I think. There was a home audio speaker demo of a single full range driver (Louther or fostex) and it was nothing special (like a louther or fostex system in other words) and I saw there was a muRata super tweeter (ES103 or ES105) on top of the speakers. They were off and I was glad as I figured they would act as sonic lasers and burn the ears with HF (15k to 100k Hz). BUT when they turned them on the boring full range speakers came alive and the image locked in and it still sounded sweet and pleasant. My preconceived notion was destroyed.
You can try ANYTHING in car audio, worst that will happen is it will fail. There are too many folks who violate the 'rules' of car audio design with tremendous success for me to even try to say what a rule is or should be.
Sorry loud'n'proud I have heard WAY too many cars that violate the 18" rule. Many are on this forum
I have heard the windshield used very effectively as a reflective sound source and I have also heard utter failure (same car different points of the competition season). The frequency band used can be very important

the bias your refering to is usually amplitude caused and can easily be taken care of by lowering the output level of the closer tweeter.....
