Re: Tweeter Placement

Oh, well I'm planning on selling them. Their aftermarket, so hopefully I can get some of my money back.

And i'm not sure if my head unit has filtering.. It's an Eclipse SE8365. But I'm always finding new stuff, so it may have it and I just don't realize it.

And yeah, 18w RMS from the head unit.. Any way to bridge that to 36w RMS to the back two once they're the only ones powered from the head unit?>

For the back speakers, I have Eclipse SE8365 6.5" 3-way coaxials in stock speaker locations. They're wired to the head unit (no amp). Frequency responce 90Hz ~ 40kHz ±3dB (source: woofersetc.)

And that will be all once I get the new components. The components will replace the second set of Eclipses in the front doors, and I plan on taking out the Pioneer 4x6"s in the dash.

Note: Do you also agree that I should take the 4x6"s out of the dash?

The Type-R is a decent subwoofer and I normally set the crossover on these at roughly 75Hz(12dB)-80Hz(18dB) dependong on the slope. On those Eclipse coaxials I would set them at 115-125Hz when running 50WRMS or more to prevent overdriving and give you entend life out of these. As for off of the deck, unless your HU has filtering on its internal amplifier you have no choice. If it does, with 7-14wrms I would set it at 80-90Hz. As for your components, hopefully thier freq response will allow you to set the crossover point to 75-80Hz to allow for enough overlap and midbass. I hope this helps and good luck in your install. I wouldn't remove the speakers, but i would disconnect them.

By the way --- Which two speakers am I getting? And which am I missing? Am I getting a woofer and an image tweeter? Or a main tweeter? Basically, should I look into eventually adding another tweeter for imaging, or does the FG set cover all frequencies well?

If you are getting a CDT set they have the main tweeter (and an image tweeter slot on the crossover) then you can buy the new upstage kit to bring the sound stage up. I'm not sure how the upstage kit works as it looks like it has its own crossover so I guess it ponies off the main one?

ankles. Ohh and I know plenty about the sience of car audio, you just mis understood my joke.

My mistake

, I do see your point from the engineering standpoint of the factory engineers. But they are centered around cost and ease of placement VS what is necessary for good stereo. Thank you for the clarifying that.

As for the crossover point that is normally decided by the passive crossover network that is included with your components, this specification is derived from the frequency response of the two drivers, slope, and the amount of overlap they need for flattest response. The tweeter x-over point is 1800Hz on my components. Traditionally a tweeter will be x-over'd anywhere from 1500Hz (oversized tweeters) up to 3000Hz. This information should be in your manual. This is the freq that you will base your placement on.

Now if you are asking what the x-over setting on the amplifier should be this depends on how low your system can play cleanly under amplifier power and whether or not you have a subwoofer to augment the bottom end on the stereo system. A decent system can be crossed over as low as 75Hz, high end systems can be filtered as low as 40Hz or require no additional filtering at all. Lesser systems must be filtered as high 150Hz to protect them from overdriving. So the short answer is trial and error, unless you can give me an idea of the freq response of the different portions of your audio system. Good luck in your install

Re: Tweeter Placement

Prometheus, what would you recommend to set for the crossover frequency?

They are going to be powered by a Hifonics ZXI 6006 (150w x 2). The rest of my system is be (2) Eclipse SE8365 6.5" in the back, and an Alpine R 12".

I plan on taking the 4x6" speakers out of the dash, and only having the components up front. (pioneer at the moment).

Also, this site: http://www.cdtaudio.com/speaker_placement.htm recommends angling the woofers upward. Is that worth building a custom speaker mount to make happen?

Re: Tweeter Placement

With my component setup i basicly did a figure 1 and figure 4.
http://forum.realmofexcursion.com/sh...ad.php?t=15028
I was planning on mounting the tweets in my pillars but the way they curve would have placed the tweeter to close to my head and would be quite over powering.

How ever in the rear stage the components were able to be wired coaxily while still letting me take the 2nd tweeter and mout it in the stock dash tweeter location.

Re: Tweeter Placement

Yep i wanted my tweets as close as possible to my mids that i decided to go with a good coax instead.

Sounds better than a lot of component systems i've heard

(am not the biggest fan of having the tweets high up and so far away from the mids. just doesnt sound natural to me)

Re: Tweeter Placement

Fig 2 would be most recommended for proper tweeter placement and if you aim them properly your soundstage will be high and centered. This is not a new concept, this is what the Q-forms were designed around. Every training I have ever attended Alpine, Eclipse, JL, and not too mention Oz Audio (Only company to score *perfect* in SQ competition)has confirmed this as the best placement for performance. As for distance from the woofer this largely depends on crossover frequency. Tweeter distance should be 1/2 a wavelenght or equal to 2 wavelengths of the crossover frequency. For my components these distances were 3.25" or 15".

I don't think its fair to say that Chris Yato and Steve Brown listen to through their ankles or have their heads up their highly respected asses. If you don't understand the science behind placement please keep you comments to yourself so that those who are legitimately eager to learn can do so without distraction.

Re: Tweeter Placement

I think best place is where it shows in the picture
this is for good sound image:

but you can either put in in the stok place or near the kick panel and listen to the music and decide like this pic:

Re: Tweeter Placement

Alright.. Well what I think I'm going to need to do is stop by a junkyard and see what I can come across as far as door panels/pillars go, because so far it sounds like the stock 4x6" spot isn't an option.

The car didn't come stock with components, so if I'm ever selling it, I don't want to modify anything I can't undo (with exception of deadening/minor details)

So would the best place be either at the bottom of one of the pillars or at the top of the door panel near the window?

^^^^^^^^^^^this is how the Factory Builders do it Go Figure^^^^^^^^^^
No you put the tweeters as high as possible( when its the door ) but close enought to keep a proper time alinement ( within a foot of the other speaker )
In this case the speakers are in the dash so you can put the tweeter in the pillar and be fine.

I will agree with both of these gentlemen…
my 2 cents is that it is not necessary to have them exactly within a foot…

Re: Tweeter Placement

So you're saying I should put them down by where the mid-range woofers are going? Or futher up on the door near the door-handle? If they're down near my feet, wouldn't they be less.. direct? Because the shorter soundwave won't travel like lower frequencies where they can go all over?

Either way, is it going to require cutting the door-panel?

And as for adjusting the mounting angle, are you referring to them going in the 4x6" spot, adjusting them so they're not aimed at the windshield? Or are you referring to putting them in the kick/door panels?

Thanks for the help.. the post was helpful.

Re: Tweeter Placement

if your goal is building a soundstage worthy of SQ you should put the tweeters down in the kickpanel since this will minimized the difference in the distance to the listener. Refrain from mounting them where the factory plates were since the reflection off of the windshield will color the response making them sound overly harsh. You will have to adjust the mounting angle so that the tweeters are playing up into the listening area.

Re: Tweeter Placement

I think some people are confused.

The component set consists of 2 midbass drivers and 2 tweeters (and x-overs).

The midrange drivers are going in the doors, in the stock 6.5" mounting location. I'm wondering if I can then put the tweeters where the current 4x6" speakers are.

The speakers (midrange) aren't going in the dash.

This is where the midbass drivers are going (bottom of door)

I'm not sure I've heard that before. (not saying you're wrong-- I know nothing about tweeter placement).

Wouldn't that suggest that Coaxials have better sound stage than components?

Re: Tweeter Placement

Yeah, i figured the absolute best place would be in the pillars, but if possible, it'd save a lot of interior modifications to put them in the stock 4x6" location.

I guess what I really want to know is whether or not there will be an extremely noticeable difference in sound quality between the stock 4x6" space and the pillars.

And @PFT - You sure you're not mistaking tweeters (1" circular). If you can see the spot on the dash, where the grill is, there are 4x6" 3-way speakers there. And there were stock 4x6" speakers, as well.

and @XBlazer -- I'm not sure if the speakers in the dash were an option, but if they were, I got 'em because it's fully loaded. There were stock 4x6" in the dash.. But I'm wondering if Tweeters in the same place will perform to full (or close-to-full) potential.

Re: Tweeter Placement

The blazers have the speaker up in the dash but the Jimmy's only had this as an option.

Re: Tweeter Placement

well i have heard the best place is at the bottom corners of the pillars and to aim them across to the opposite seat.. if u want to get technical u can use a laser pointer and aim them that way ....
