Where should I put the tweeters? (with pictures)

I removed the stock 6.5"s on the door (F) and stock tweeters at (B).

This is a sample picture of what I am planning to do next. I want to put CDT super tweeters (Image Enhancement system) at (A) to make the iamge "upstage", and CDT Braxial at (F). By doing this combination, I don't need to mount the tweeters. Do you guys think this setup will work out?

Or, should I get HD-62 with seperate tweeters and mount the tweeters somewhere else, either on the door, or kick panel? I am not sure where to mount the tweeters and that's the reason I can't make a decision between CDT HD-63 Braxial and HD-62 Components. Should I go for Braxials or Components with seperate tweeters? Any opinion? Or maybe you could tell me the possible location for tweeters if you were me?

B. Is the best place to put it cause it just is. :idea:

But it's not the best location. I want to find the best location of the tweeter while the midbass in the door.

To the best of my knowledge and suggestions from car audio installers and shops, they told me mounting the tweeters in spot B or C is the best for imaging.

But isn't it also true that the tweeter is better off closer to the woofer, in order to create the "DEPTH" of sound stage?

Ok you ask for people's opinions and when they give them you seem to know a way to turn down their suggestion.

You ovbiously have read about tweeter placement so why are you even asking us our opinions when you probably already know where your going to put them.

A is ugly and will ruin the car. All are an ugly place to ruin interior in my opinion and make it look like it doesn't belong.

I would just put it in B.

You could use DSP and then place the tweeter anywhere. You'll be able to create the image that you want.

:shock: I do appreciate everyone's opinions, but I also wanna know WHY. This is a discussion forum, thus we discuss. I look forward to an explanation why you think it's the best. It's true that I have read MANY things about the tweeters replacement and I read there are Pros and Cons for each location. It also varies with the interior of the car as well as many other variables. That's why I ask. I want to know people's opinion and the reason, not just a straight answer.

B will be the cleanest setup, but I wanna know if it's also the best for image before I mount the tweeters. So do you know anything about soundstage and imaging? CarbonB?

The best spot in my experience is at the top of the A pillar. The second best would be position B. Positions C through F are too low.

What you want for best imaging is to get equal volumes from each of the tweeters at both the drivers position and the passengers position - most of the stereo information in music is in the higher frequencies. The best way to do that is to mount them high so legs don't obscure the sound and try to point the passenger side tweeter directly at the driver's head and the the driver's side tweeter at the passenger's head. A flush mount at position B will not work very well - you'll have to angle them back and upwards. Tweeters are very directional and so the off axis response drops off quite quickly. If the driver's side tweeter is pointed at the passenger's head, the sound volume reaching the driver's head will be reduced by a few decibels and if you're lucky it will be the same level as the sound volume coming from the passenger's side. Choose your tweeters carefully. I would suggest something that has an off axis response at 45 degrees of about -5 dB.

There's alot MORE to Imaging than just driver placement-- Pathlengths, Time Correction, Standing Waves, Early reflections, Linearity, Phasing, and many more all contribute to proper Imaging.

To answer your question:
Theoretically-- It is a well known fact that the tweeter's optimal mounting location is right ON the midrange driver (Coaxial setting) The idea is to have the sound come from a SINGLE LOCATION. In Acoustics, this is known as "PointSource Location".

But there is a problem with this setup-- The tweeter would interfere with the sound that's coming from the midrange.. that's the drawback of this design. True Single PointSource drivers will play in full range- Most of these drivers are found in High End Home Theater setups and are very expensive. They do not require separate tweeter and midrange.

My favorite driver location is the Kickpanel, WITH Tweeter, attenuated to -3dB AND a NON-Attenuated Tweeter in the Location "B" (A-Pillar) The reason for doing this is because you want the midrange AND the Tweeter to be PointSource. The tweeter in the A-Pillar is NOT attenuated because we want to bring the SoundStage UP, so the vocals would "seem" to be coming from the hood of the car, not from the Dash. The reason for attenuating the Tweeter on the kickpanel is so that it won't drag the SoundStage down, AND so that it won't create Phasing problems against the tweeter in your A-Pillars.

Let me know if you have a chance, we can meet sometime and I will let you audition my car :mrgreen: There's too much to explain, we can go on and on for weeks. Trust your own ears, not what people tell you.

sorry, very long. :mrgreen:

I know. The more I read, the more confused I get. I'd love to meet with you if possible. Maybe next weekend, or whenever you have time. I am very interested in Car Audio now and trying to absorb everything in the forum. Thank you so much for your comments.

Anyway, these speakers I am ordering,
TW-25/LP Image Enhancement System


CDT HD-62 6.5" 2-way


And their recommanded setup


I wanna do the doube tweeter setup. I'll have to play with them w/ differnt location once I recieve them.

Here is the link from CDT Audio. They are not main stream but their speakers have very SQ.

man I'd kill for the EuroSports.. but they are just so... expensive

But good stuff aint cheap
