let me take a second out of my day and say that you DO NOT have to mount the tweeter as close as possible to the mid driver. all of our comp vehicles have the tweets mounted in the a pillar ( for staging purposes) let me tell you we build them all day long and i don't want the person who started this post to think that they are stupid due to the in competence of someone telling them they did something wrong!!!!

i'm not trying to be hostile but i am aware of these things about distortion and the amp clipping so its no news to me. i did not over power the tweeters unless the wattage they say is blown out of proportion, which it probably is. they are phoenix digital tweeters and i only have arount 120 watts going to each speaker because i don't want to blow those expensive fosgate speakers or ruin any of my other stuff either. the tweeters "say" 300 watts but that is most likely bs. i checked them to see which ones were left functional and they all are nonfunctional so i most likely overpowered them. the reason i posted this is to see if any of you all have heard of a tweeter launching itself before, that is all. sorry if i came across as hostile.

Those "300 watt" tweeters are probably good to 50 watts, so that could be the problem.

I've mounted tweeters in that same location and they sounded just fine to me, but I'm not audiophile. Kind of funny about the thing exploding, glad you didn't have a wreck or anything when it happened!

why does everyone get their panties in a wad when someone says somethin they did might be "wrong"........ get over it....if you knew what you were doing you wouldnt be on this forum askin questions. Since you are, dont act like a badass when someone questions your work. Like its some shameful horriable thing to admit you might have screwed up.

Yes the currently accepted norm is to put A Piller tweets in, but that does not change the rules of nature. When you move the tweets away from the mids (or any two speakers that have some frequency overlap) you create a comb filter.

The tweets in the A-pillars should be only from 12k-15k and up and should be modestly powered in comparison to the main tweets which should be located close to the mids. By doing that you can raise the soundstage.

Have many cars been done this way? Yes. Do they sound good? Yes. Does that make the rule of thumb obsolete, absolutely not.

Many judges scored 7 time world champ Gary Bigg's car higher when he rebuilt his grills to look like he had changed his speakers to aim more at the listener when the speakers behind the grill were still off axis like they always had been. Many of the same judges assumed that since the top of his dash was grill cloth that he had a center channel and some even commented on it to him if I remember right. Nope just one component set in his kickpanels that were firing basically directly across the car. But the mind will tend to hear what it wants when the eyes tell it something about the location of a speaker.

There is always a right way and varying degrees of less than right, but the right way always works, period. The other ways can be made to work "good enough" that 90% of the world never knows the difference. I just have found over the years that the right way is usually the easiest way to obtain and retain results over the long haul.

You saying I'm imcompetent on car audio or the general physics of sound recording/reproduction...sorry you're wrong, everything else in life, well you may have a point but I do know a bit about sound. I work for an audiophile recording studio, I have designed and helped build a car that won a world championship and placed 2nd (with a higher SQ score than first) another year, I have helped build SPL vehicles (one of which was a record holder that year), so don't tell me that I'm incompetent on this issue. Can I be wrong on something? Yup happens all the time, but just to be sure I've checked my responses with a couple of knowledgable guys and have been told that I'm on target here.

I wasn't bagging on you, crzyone1013, sorry if you took it that way, I tend to be a bit blunt. Did they really explode or maybe the heat from being driven at a modest level caused their glue to fail and one just happened to fall apart, being that it is mounted where it did, it fell down on your arm? I've seen speakers come apart like that before (actually caused it to happen in a couple of experiments, yes i was bored).

I may have posted this twice, the first one did not show up.

we should call the site soundsourcemag.com now lol. Its amazing how much some of you guys know

I should also mention that most of the current trend of putting tweets in the A-pillars could be traced back to 7-9 years ago. A few competitors started putting tweets in their a-pillars but NOT HOOKING THEM UP in order to head fake the judges into higher scores on the height of the soundstage.
It worked, the non functioning tweets somehow raised the soundstage, and installers across the country saw the pics and copied the layout.

no glue failure here. i found the empty casing of what looks to be a resistor or something like that in my arm rest. and the stuff inside it looked kind of like nasty cotton or something. i checked and have asked everyone i have seen who knows about this stuff and none of them have heard of it either. i actually have the front half of the tweeter right here in front of me and the remanants still mounted in my truck. i will take a few pics of it and show you all if i can figure out how 2 post them on this forum. i have now gone back through my setup and upgraded to much better stuff. i now have all kicker ss components.4" ss coaxials in the dash, one 8" midbass, one 6 1/2" component in the lower front door panels, and the ss tweets mounted at the top front of my door panels. i am still considering mounting an extra set of tweets back in my a pillars because i like the sound. i am also switching amps to a kicker kx600.4 so i can power thes new speakers. i have 6x9's in my back storage panels but they might-as-well not be there because they are covered my my massive box for the subs.

Yeah those rear locations kinda suck, like maybe the OEM didnt care about sound...

The capacitor (passive crossover) built into the tweet or its wiring probably exploded.

so which is it? a 240 watt sony or a 400 watt sony? Having the amp "turned down" does not decrease the wattage, it matches the level so that all the way up on the head unit is max amplification from the amplifier. Stacking multiple pairs of speakers with passive crossover networks increases the likelihood of overdriving your amplifier. And its not fair to discount my advice because its something YOU dont want to hear.

The empty casing with the cotton wadding you describe is a capacitor, not a resistor, because thats the least expensive way to filter a tweeter, and DC on a non-polarized cap will blow it every single time.

it is a 400 watt 4 channel amp. so 100 watts to each speaker if i am not mistaken. so sorry i didn't type the EXACT wattage to the speakers, russ d. as you said DC on a non-polarized cap will blow every single time why didn't all of the tweeters blow? answer me that. since you aparently have nothing better to do with your time than TRY and make people look stupid. if i had the time to waste i would let you debate with all of the people that were involved with the installation and stetting of my stereo. I would gather them but I'm sure they have better things to do than show yet another person who knows what the fuck they are talking about. after all they do make a living installing and competing. so i will end this with a fuck you, have a nice day.
