Looking for ideas on where to mount tweaters in the FD for a component speaker system in the doors on my FD.

Any pics would be great! Thanks!

 

I would mount them somewhere near the windsheild so the sound waves can reflect off the windsheild towards you or who ever is listening. You don't want sound coming from the side or back, you want it from the front. Like going to a concert.

 

i put mine in the door panel like this

than i put it in the rear panels like this

 

I like the drivers door placement, but the passenger side doesn't have that same spot. For some reason, I like to be equal on both sides of the cabin and on both doors, but there is no portion of both doors that is the same, so I'm curious where guys are mounting them.

 

I dont have pictures but i would mount them on the pillars so that way you can hid the wires and they would have the glass effect like SYTP said and you can mount them in the same spot.

 

if they went in the pillars. wouldn't you point them at the people and not get any glass reflection? or would you piont them toward the windsheild?

 

Pretty sure the sound waves would reflect from the windsheild also, unless the tweeters are mounted at an extreme angle where it wouldn't be pointed any where near the windsheild. My Tweeters are located on the A pillars (around 2-3 inches above the dash). But then again, you might have problems installing gauge pods in the future.

 

I don't plan on doing any gauge pods on my car, so putting tweeters on the A-pillar sounds like a good way to go.

Anyone have a pics of thier speaker placements?

 

Not the greatest idea unless your going to put the mids in the same gauge pod (dont think thats physically possilbe)

See, sound travels at a certain speed... put a speaker closer to you than another.. and youl hear the sonud out of that speaker first.... youl get all sorts of problems and shitty sound... unless you have a real sound guy set up delay times from each component (which i doubt youl find)

So what im saying here is.. make sure you put the mids/tweeter set as close as possible to eachother.

 

That makes sense. So, with that in mind, where are people mounting the tweeters?

 

doorpanel, facing you, would be the best idea

 

Might want to consider playing with the tweeters the kick panels. The idea is to minimize the path length difference between the left right sides as much as possible. See the Streetworks Buick entry:

http://www.termpro.com/showcars/terminator/ca1096.html

This car was absolutely tearing up IASCA, back when I did a few shows (it used waveguides IIRC, but same basic principle).

It's counter intuitive, but you have to remember that the ear does not sense height as much as it does left/right. By increasing the distance to the ears (and minimizing the difference between the timing that sound reaches from either side), its easier to create a deeper, wider soundstage.

As turBRO240 mentions, it's best to keep the front components grouped as close together as possible. When a singer sings, the highs and the mids, it comes from the same point.

You haven't much room in the kick panels of course, there, so might want to try tweets and mids there, with mid bass in the doors/stock location. I had tweets and a 4" mid in the kick panel and 6.5" in the doors. Had really good SQ, but in the end, I still wasn't competitive due to my platform being a regular cab mini Toyota P/U. Not the best place to start. With the FD, the same layout should yield better results.

Boucing sound off the windshield colors the sound IMHO.

 

search 6.5" JBL i did an install and loaded all the pics on here

 

Is a bad pics but it give you an Idea on what i did. here or on the A-mount is the best solution according to me.
In the little triangle like i did you still may mount in the future the gouge pod.
Bye

 

Anyone use 3 way speaker in the front?? how to fit a little midrange in the front??
post a pics.

 

actually... it would be better if you mount the tweet on the apillar facing the windshield than the above setup.... why? because like this, its the worst case of sound delay... the sound from the tweeter will travel to your ear much earlier than if it was facing the windshield... the sound reaching the windshield then reflecting to your ear will be more in-sync than if it wasnt.... unfortunatly you DONT want the sound to be refelcting off somthing then reaching your ear... but theres not much you can do about it if you mount anwhere around the A pillar..... unless you want to go reallllyy advanced and setup a time delay for the speakers (which most of you probably dont even know what it is.. so nvm)


the kickpanel thing is kind of interesting though.

 

I'm planning to remake the stereo, You looks like one who understand (i know what is the delay for speaker) what do you suggest me about mount midrange (3 way system) on the front??
What do you suggest me as speaker? infinity??

 

not that most people don't know what delay is - its just that most people don't want to go through the hassle (in time and/or money for processing equipment)

but, agreed with dclin, putting them into the kick panels would result in better sound as you would have more path length to play with

 

hmm.. not really sure about the 3way comps... i mean, a good 2way will do just fine for even the most ****.

Infinity makes great speakers... but if you have the money, id go with MB Quart components

 

not a big fan of mb quart ever since they were bought out...

but in terms of components - what is your price range?

there is alot of stuff out there - i have my high / mid / mid-low beyma driven... (and a set of jl's for sub) so it depends on your price and affinity for sound - anywhere from morels to hertz to dynaudio to seas to eton (high end) all the way down to phoenix gold so....

 

True... but its not super hard... all you need is a delay processor.


Sound travels at 1130 feet/second. Youl need to put a delay on a speaker thats closer to you by foot/millisecond. So, delay needed = 1.13ms/foot. Just multiply 1.13 x ft. = delay in milliseconds.

Now for some examples, let X be the speaker farther away from you and Y by the speakers that is closer to you, if speaker Y is closer to you by 1foot from X, then the delay needed to be put on speaker Y would be 1.13ms.

example chart;

Distance (ft.)-------Delay
-------1 ft.-----------1.13 ms
-------1.5 ft.---------1.39 ms
-------2 ft.-----------2.13 ms
-------2.5 ft.---------2.82 ms
-------20 ft.----------22.6 ms

REMEMBER: You want to be extremly acturate... it dosent have to by by the fraction of an inch.. but the inches better be AS CLOSE AS POSSIBLE.

ps. sorry metric people.... just use a coverter.

 

I have already MB quart on the rear 6.5 with the titanium tweeter, they sounds good but don't have a powerfull bass, wich is not a problem on the rear because i have the sub. on the front i woul like to have something powerfull to avoid all the sound coming from the back.
About the 3 way system: since the woofer thats make the mid frequency (from 750 to 3500hz) is mounted at a very low position covered also by the leg, don't give a good response to the ear. I solve this problem partially putting a midrange in the center canal of the RX7.
On the back i will probably improve my speacker with a MB quart 2 way component 6x8 wich will improve a bit the bass and the will fit perfectly on the rear predisposition on a FD.

Why we (You are better than me) don't cooperate to make a little guide on speaker or system to evrybody?? I will remake my system and i can put a lot of pics.

 

Id love to see some pics with a description/writeup from you...... but believe me, you dont want to overdo it with too many actually components/speakers... it makes getting good sound actually more difficult.

Also... utilize crossovers as much as you can. Seperating the frequencies to the correct speakers will make a huge differnce.
