Default quick question about tweeter placement

Can someone tell me whether it would sound better to put my tweeters in the doors(in front of the handle bezels) or to put them in the a-pillars(facing the winshield). I'm leaning towards putting them in the a-pillars, but I just want to make sure that I will be able to hear them very clearly and I won't loose any volume by having them there. If it helps, they are Diamond Audio D6 Components. Thanks in advance.

i like the concept of having the tweeters firing directly at me, so i'm trying the tweeter pod idea at the top front of the door. But i deffinatly don't have the right degree to tell you much about sound dynamics inside a cars cabin.

Mine are in my doors up high, in the black plastic area of the door panel. Sounds great.

high frequencies(tweeters) are very directional. its a law of physics. the higher your tweeters are the higher all the sound from the front will sound. it tricks your ears. i would try to get them as close to eye level as possible but to an average person the door is ok. i have done that many times in the past with good results.

yeah the tweeters from the set of mbq's that i just removed were installed in the doors right infront of the handle bezels next to the dash. but what i didn't like about that was that in order to have the pass. side tweeter at the same level as the driver's side, the pass. side had to be all jammed up between the are vent and the handle bezel and it looked like ****.

well i tested it out a little bit ago. it sounds MUCH better high up in the door panels. i tried moving the tweeters all over on the pillars but couldn't get a better(imo) sound. so i think i'll do the install in the doors myself this time and hopefully do a better job than whoever did it the first time.

also, does anybody know if my mbq woofers are worth anything? i'd sell the whole component set, but the crossovers are rusted and one of the tweeters got crushed beyond repair(window tint guy knocked off my tweeter pod and then close it in the door). so now i just have the woofers and one tweeter.

For the most accurate sound from your system, two key things come to mind first.

1. The tweeter needs to be as close to the mid-range/mid-bass speaker as possible.

2. The tweeter and mid need to be as far away from you as possible. Reasoning: The further away the speakers are, the closer your ears are to be equal distance from them.

Sure, putting them up high in the car will bring the stage of the sound up higher. Will it sound accurate? No, not without some serious tuning/imaging equipment. Will your image be in the correct place? Nope.

hmm well i guess i just dont care much about that. i like my sound stage up higher and i cant tell any difference in the accuracy. every car audio guy has told me to try and get your tweeters as close to eye level as possible. but either way, it sounds amazing with the tweeters where im putting them.

Every car audio guy you've talked to does not know what they are talking about.

Go to a car audio show, talk to and look at the guy's that have SQL setups. These setups are made for sound quality.

If you listened to a CORRECTLY setup sound system in a car, you would care, trust me.

Not everyone has the time, care, or effort to go that far though. Just put them wherever they sound best to YOU, since you're the one doing the listening in the car most of the time anyways

Here's where I put my tweeters (see attachments). I'm sure there are other spots that work well, but this sounds pretty good for me.

that looks good. good job on it. and no i don't care nearly enough to drop tons of money on a sound system. and the guy that gave me the information owns car sounds on rufe snow dr. in north richland hills, tx. he has about 10 first place trophies from bass production and has almost 15 1st place show finishes. to me, thats pretty damn good. and where i ended up putting the tweeters in my car sounded better TO ME than another other spot that i tried putting them.

sql is not sound quality, sq is sound quality.....
The tweeters you have make a difference also, because some jst dont sound that great off axis.

You're both right. Moving the tweeters up does improve the sound stage positioning. But you don't want to separate the tweeters from the mids by enough distance that you can hear that they are separate components - they should be close enough together to sound like a single sound source. Unfortunately, that is pretty difficult to do in a car (you don't want to mount mids in your upper door).

BTW, most vocals don't come from the tweeters anyway. The human voice has a range of 300Hz to 3400Hz with most vocals (especially male) between 300Hz and 1200Hz. There are exceptions of course but generally your mids carry the bulk of the vocals.

However, personal preference is what should determine your speaker placement. If you like the way high-mounted tweeters sound then don't let anyone tell you you shouldn't do it. Many "audiophiles" insist that there should be no speakers except subs behind you to have a front sound stage but most people like the surround sound effect of having speakers all around.

I definitely looked out for "separation" in the soundstage, couldn't hear it. The midrange seems to be filled inside the car, while the tweeters are brightening up the soundstage. Honestly, I couldn't find a better spot for the tweeters that sound good and look decent (I really wish I could've flush-mounted them).

BTW, using Kenwood KFC-P603 6-1/2" components, if that matters.

Oh, and regarding rear fill: I tried with and without it, and I definitely like it better WITH rear fill. I have my system set up so that the fronts are a little louder than the rear, just enough to maintain the front stage (front components are amplified, rear 2-ways are powered from HU).

yeah my gain and frequency are set higher for the fronts then for the sails. i have an amp powering both. and i completely agree with rear fill, it sounds much better to me to have the "surround sound" effect.
