Good day again to all!
I'm thinking of adding tweeters to the rear speakers in my suv. At present i have infinity ref 6010cs components in the front, ref 6012si coax in the back doors and a sub in the rear. Infinity has a reference 1011T 1" tweeters that can be an add on to the rear speakers. Question: Is it better to replace the rear speakers with 6010cs compnonents or will the add on tweeter do the job.
Thanks again.

The add on will do the job. The question is how much highs are you looking for.
Obviously the coaxial tweeter is not doing the job you want it to do. Probably because of the location (not firing toward the front cabin). An additional tweeter will work fine in this case. I would suggest using double sided tape and mounting the tweets in different locations until you find a sweet spot where everything blends together nicely. The use of seperate tweeters in addition to the coax speakers could very easily result in too much, so placement is going to be the determining factor here since there is not an easy way to attenuate the volume of the add on pair of tweets.

Thanks for the input.
You got it right, in saying that the coax are not putting out the job i was looking for. Guess it's because their door mounted (original factory) location. What i'm looking for is clarity for the back seat riders, although not too much as to overwelm them. I'll take your suggestion on temporarily mounting the tweeters until i find that "sweet spot".
Again thanks.

You may note some extra SPL from the addition of tweeters to if you go parallel to the amp that drives these speakers and add on tweets. Here, you'll be at 2 ohms per channel.
Don't be too surprised if the new tweeters come on a bit stonger than you might like. But there is a fix for this too.

good day swez.
actually that is a concern of mine. adding the tweets will surely make the sound brighter, but i figured adjusting the frequency on the amps crossover would do the trick. also, i've seen some pictures of tweeters being mounted into the door sidings. looks very neat although that would mean punching holes into the sidings. At any rate, will see if this will work out.
Thanks.

If you find the tweeters in back come on a bit strong, can always add attenuation resistors to trim them back as needed. These resistors are inserted between the power source and the tweeter crossovers... like this:
Amp output +...........www....... + Crossover....... +Tw
Amp output -....................................................... - Tw
The ----www----- is an attenuation resistor.
Adjusting the amp gains for the rear may help too. But if using EQ, this will also affect your front speaker highs too.

OK. Thanks again for the input.

Also, if you can mount those tweeters at or nearest to ear level this will make a HUGE difference in ambiance.
Ash on 02/11/2007 12:00:35
Why do you want more high frequencies to come from behind you? If your'e not getting enough ambience up front then you could use the extra tweets in a different location from the comps.
For example:
You are using comps in the front doors with both mid and tweet located there in close proximity. Sounds good except your needing just a tad bit more sound to engulf you.
A good solution to this would be to use extra pair of the same type tweeters in the pillars, dash corners, etc.. They could even be run off the HU for easy attenuation. This will help lift the sound stage up a bit and give more clarity without any treble/eq adjustment that might affect the rears as well.

Good day guys.
Thanks for your suggestion Ash. The aim in adding tweets to the rear speakers is for clarity to the second row riders (and in a way, the third row as well) . While adding the tweets up front sounds reasonable for front staging, would it not overwelm the driver and front row passenger? I know its easier to create a front stage in cars, but since this is an suv, i figured adding the tweeters would do the trick.
At any rate, i'm still open for ideas.
Thanks again.

You can mount tweeters anywhere you want. It's always been my experience that rear mounted tweeters sound best mounted behind the passengers head at or near ear level. Nissan does an excellent job (out of their way actually) with speaker locations in their vehicles. If you can, head on over to the lot and check out one of Nissan's SUV's for rear speaker location ideas--take a ruler.
rldelrosario on 02/12/2007 00:08:18
Thanks for the suggestion. Will likewise check it out.

It also depends on the tweeter's "polar dispersion patterns". Some are very narrow and "beam" into one's ears. (Line of sight thingy) Others have a wider angle of dispersion and sound very good at 30 - 45 degrees off axis. Knowing the difference between tweeter A,B or C, makes all the difference.
This is where some experimentation is needed. (Temporary mounting of a given tweeter) A cheap tweeter is very directional and "beams" a lot of high frequency energy right at the focal point. Better dispersion
tweets sound great in both off and on axis mountings. Knowing this factor, really helps to obtain great highs in the front or rear stage. That's what Blue is alluding to.

PS Since tweeters are often line of site drivers, we can use hard surfaces to bounce or disperse their energy. (Ie: Leather/vinyl seats, plastics & glass act as deflectors) Cloth seats and carpets absorb HF signals. Balancing these variables, make(s) all the difference.
Ash on 02/12/2007 20:21:48
Ditto on the dispersion characteristics Swez.....
If you really want to give the rear passengers a decent stage as well, then I guess your right. But, what about using the same type setup as the fronts with similar positioning? If done this way, I would think the imaging would be maximized with less tonal interference with the front.

Good day to all.
My concern exactly ash. If you check from the top, i was in between changing the rears to components or just adding tweets. Ofcourse the first option will cost a little more but would it be worth it.
Actually what i have in mind now is to bring the vehicle to the store, have the tweets connected (temporarily ofcourse) and see how it sounds. If it does the job, then i can go ahead.

I am a newbie but I am using the same infinty 6010cs and I have components set in the front and back and it sounds good so I know what you mean about the back seat riders cause that a good distance from the front to the back. I would use a second component system if I were you. Plus I just like highs so I love it that way.
rldelrosario on 02/13/2007 22:10:24
Thanks for input Hoova63. Yes, exactly. Like i mentioned, i'll try the tweets and see, but having another 6010cs would seem like a wiser option in the long run. Nothing like good highs to hear eddie van halen leads.
