Has anyone put seperates in the back of a teg. If so where did to install the tweeters. I just installed alpine seperates in the front and it sounds so much nicer. The highs are really nice. I was thinking of doing the same in the back. if you have pics that would be cool too

 

i wouldn't recommend that you install components in the back, it will screw your staging up big time. Lost of SQ guys go ahead and remove all the speakers in the back, just components in the front, amped and subs. Or you can throw the mid's in the back and put the extra tweeters somewhere in the front, ive heard of this being done as well. Something like a pair in the kicks and a pair at the top of the A-pillar.

i agree on not using separates in the rear completely, unless you are using a door mount.... i.e. jetta, volvo etc, even then the speakers are way to close to the driver's ears and will create a bad imaging effect if not toned down via amp gain in the doors. Separates in the rear deck are useless altogether because the sound created by them will just reflect off of the glass in a 4-dr integ and fire at the back of the driver's head in a 2 dr.

However, I do disagree with the extra tweeter up front idea. How do you think the amp is going to respond to another 4 ohm speaker in line with the crossover? If you bridge parallel you're doubling your distortion and creating a 2ohm tweeter assembly, which you're crossover may or may not favor.

Next, the optimal placement for a tweeter in a component set is not more than 12 inches away from its accompanying driver. In most cases the tweeter should stay as close to the driver as possible while staying within earsight becuase of the high frequencies' directional properties. Besides the kick panel is the BEST location for an even front stage in an SQ environment, and I dont think this guy is competing.

Sell the components and get some decent coaxials for the rear.

 

WARNING: two sets of components will often cause sudden deafness, convulsions, or even, death in some cases.

 

i never recommended that he wire the tweeters together, or even to the same crossover. if he wanted to do it he could run longer wires to the crossover for the mids in the back.

 

then they would be roughly 14 times the recommended distance from the mid range they accompany, and the rear image would only be midrange. Doesn't make sense to me at all. With the correct power, two tweeters positioned correctly in the front would be more than enough for any persons needs.

I don't know where you get this information, but you really shouldn't be giving advise in this section. IMO just based on the last two theads i've read.

 

for SQ you dont want much imaging at all in the rear. Besides, read what i said first. I recommended that he not go with components in back. The rear should have a very minute delay, a few miliseconds and be should be almost faded completely out.

 

then you went on to recommend he place the tweeter from the rear component set, somewhere in the front..... Now... in an integra...where do you recommend he put this extra tweeter, seeing as how he already has a component set up front?

 

no, i said if hes set on putting in components he could do that. Thats why i made certain to make it clear i didnt recommend that he put in components at all.

 

If the front tweets are in the kicks the 2nd set of tweets go on the A-pillars.

 

Imaging effect on the rear? Isn't imaging the placement of the instruments, musicians and vocalists on the soundstage which is infront of you?

Acutally, if the tweeter is mounted down low in the door or in the kickpanels, it will give the perception of a low soundstage. Mounting an extra pair of tweeters up higher in the car, by the A-pillars for example will raise the soundstage and improve imaging. These ambient tweeters are usually crossover over at 12,000Hz of higher and the output is reduce by at least 6dB.

These ambient tweeters need to be off a separate high pass crossover network.

Speakers are not resistors. If it says 4 ohms, it will not always be 4 ohms since impedance is frequency dependent. For a given speaker, it may be as low as 2, or as high as 103 ohms depending on the frequency. But overall it's about 4. If an amp can't power a set of components and a set of ambient tweeters, it is a piece of crap and you shouldn't be using it anyway.

Optimum tweeter placement away from the woofer should be about 4". When most loudspeaker maufacturer test their speakers response in an anechoic chamber for the frequency response, the tweeter is mounted within 4", from what I understand. But whether it is 4" or 12", it all depends on the car, the type of tweeter dome (hard dome/soft dome) and where you put the tweeter attenuation settings on the passive crossovers.

Another rear fill option is to use a raw midrange driver only for the back.

 

Imaging also means to render visually, as by magnetic resonance imaging. Whats your point.

Remember, were talking about an integra here. Chances are, his Alpine Component Set has found it's way into the door where the factory Mids and Tweeters were originally. Now his driver side tweeter is roughly 2 feet from his left ear, while the passenger side is more than double that, thanks to Acura and Alpine. At least it's not facing directly at them.

If indeed he did have custom kick panels constructed, giving the driver a more even IMAGE, then a set of ambient tweeters would be a great choice to complement his setup, as opposed to a normal set of tweeters projecting 4,000hz and up complementing their midrange that happens to be 6 feet away pointing upwards into the rear window. And most ambient tweeters carry a nominal impedence rating of 8ohms.

In the future I will now ask what you currently use in your car as far as head unit, amp, speakers, etc. before giving any more advice on this board, to avoid any confusion.

Ok I think that I made my mind up not to put seperates in the back. I like my good sound quality and if that is going to mess that up then I don't want to do it. I have alpine 2 waysj in the rear that I think I'll just keep there.

 

I've got all the stock speakers still intact, with a kenwood excelon head and a 10" bazooka in the back and the system absolutely thumps. I think if you use a crossover for the stock speakers so they don't get too much juice then all you need is a little more bump in the trunk and you'll be set .. unless of course you are an audio maniac and must have the best of the best. In that case, I'd go components up front, mids in the rear, tube in the trunk (for space reasons), and get a good amp mounted to the rear seat. Voile!
