Accurate info posted about what a tweeter is. I just want to add one thing. The lower the frequency, the slower (as already mentioned), and less directional it is. The higher, the faster, and more directional it is. So you'll never see a tweeter vibrate unless the resistors are letting low frequencies through and it's straining to reproduce the long waves.
Now to the important part about speaker placement. You can here bass sounds no matter where the speaker is placed in the vehicle. Remember the 80's when you could hear bass thumping cars from inside your house? The high frequencies go in one direction - like a ray gun. So, if your tweeter is faced away from your head, or is down by your feet, you won't hear them clearly. Placing the tweeter higher, and even angling it toward you head, gets the sound to you without having to drive the volume up. High frequencies are also more reflective (they act like a pool ball on a pool table) where bass tend to just seep through things. Remember the good old sedan cars that had speakers on the back shelf pointed toward the sky? The passengers could still hear the symbols crashing because the sound reflected off the rear window and were redirected toward them.

The first three are of a custom fiberglass soundar I built that has two 8" subs, two horn tweeters, two powered tweeters, and of course two airports.
If you didn't notice I slid the original soundbar forward, and redid the ceiling with replacement auto carpet. So the ceiling is identical to the floor material wise. (You can also see the new overhead console/Mirror)
The Next one was a quick shot of my new wheels. I replaced the stock rims with brand new 17" rims off a cherokee, to do this I put a 2" daystar leveling kit in front and waiting for the 2" shackle rough country lift to come in that I ordered december 22nd. I also had to put an adapter kit on to change the bolt pattern from 5x4.5" to 5x5".
Next is the new overhead console from a '98 zj and mirror, I have not finished with my wiring, thats why the headliner is not tacked down at the window yet.
Last but not least the first part of my entertainment system a 6.5" lcd fiberglassed into the newly covered sun visor, it hooks up to a ps2 in the glovebox.
So grand totals all the reupholstering supplies and fabric cost $40
Fiberglassing/fleece costs $13
6.5" Lcd $17 off eBay
Overhead Console/Mirror $25
Wheels/Lifts/Spacer/Tires $385 but made $135 selling my old crap so $250 thanks to craigslist
Much more to come soon
no way you got that 6.5 LCD off ebay for $17... link? Tomorrow or saturday my interior will be complete and I'm taking pics and everything. Its gunna look great
It was a public seller he was parting off an old blazer it came installed into a glove box but luckily he just cut and glued it so it was a pretty easy tear job, I currently still have three 7" one 10.4" and two 6", I just sold two t-views for $20 and $24.99 last week so before I sell more, I will put some links here.
But yeah my 4.0 has been hydrolocked twice, ran upside down for 7 seconds it still keeps coming back for more. its like that crazy ex-girlfriend that just wont quit..but unlike her, its a good thing haha
Yeah I can't wait to try mine out, I've got infinity Reference series in the doors that sound great but I'm going to turn down their adjustable tweeter and these infinity aftermarket ones oughta sound amazing with the tweeters up high.
Im a huge fan of prog/stoner rock, and the band mastodon in particular.
The new album "Crack The Skye" has insane amounts of depth, and texture.
With the new tweeters, I can hear the ride cymbal better, hidden congas, bongos, shakers, and other percussion I had never heard before. It's a new level of depth, and attack. I'm a percussionist, so good audio is a big deal to me. So is saving money.
