Could someone explain to me why in the world you would want speakers on your floor or worse, in the door?

My first two cars were Escorts and they come with speakers in the doors. I was using 3-way JVC 6" speakers in the door and the same JVC 6x9's I'm using in the Cavalier. It sucked. The stereo effect was lost because the sound from either side was badly distorted. First of all, my legs would soak up the sound from the driver's speaker and if I had a passenger, they would dampen the sound from the passenger speaker. It was even worse with the windows rolled down.

I've seen these devices selling for hundreds of dollars that allow you to mount speakers on or near the floor. If I were still driving the Escort, I'd spend more than that to get the speakers in the dash (and the tweeters in the headliner) where they belong.

That was my first major impression of the Cavalier when I test drove it. With an entirely stock sound system, it sounded WAAYYYY better than the one in the Escort that cost several hundred dollars.

it puts the speakers at a more equal distance from your ears, improving the sound stage...

I might agree if it weren't for the fact that doing this necessarily puts obstructions right in front of the speakers.

There is a lot more to mounting speakers in the kick panels than just
equalizing the path length difference (PLD). Two of which are: on-axis
response, and angling for pattern control. On-axis response refers to
the fact that most speakers sound best when listened to on-axis, or as
close to on-axis as possible. Second, after mounting your speakers in
the kick panels you can then angle the speakers to take advantage of
their off-axis response to use output level to overcome any PLD that is
still present. The pattern control I am mentioning is one of the ways a
horn loaded compression driver works very well, they not only use
amplitude to overcome any PLD that is still present they minimize early
reflections that can destroy imaging staging and spectral balance.PLD can be improved more than marginally when you consider the stock
locations in a lot of vehicles, or the locations most installers choose.
Measure the PLD between tweeters when mounted high in the dash or at the front corner at the top of the door and you will notice its probably on
the order of 24". This mounting setup requires a lot of amplitude
adjustment to correct the problems induced by this difference. The
nearer tweeter is out phase from the opposite side and is arriving much
sooner and with much greater amplitude due to the fact is not as far
away. When all these factors are added together, it is very difficult
for even the most flexible DSP unit to correct. On top of that, not
many people or installers have access to the necessary tools to properly
set up time delays using a DSP - TEF, MLSSA or other very expensive
time domain measuring equipment are required to do the job properly.
There will always be trade offs involved and deciding which trade offs
to take can be very hard. A small dropout due to phase cancellation will
probably not be noticed by most people but most people will quickly
notice when a vehicle is not imaging properly, and if you can move the
problem to higher frequency where we determine localization more from
amplitude rather than phase differences, it will be much easier to deal
with. Also, if you minimize the time/phase difference it will be much
easier to correct with amplitude.Some people complain that kickpanel mounting gives a low sound stage.However, keep in mind that when any stereo system is imaging properlythe point sources can no longer be localized. When our brains can nolonger localize the point sources it will then hear things at eye level.

That's all well and good. But set up some speakers and put a big teddy bear right in front of one. I don't care how well designed the system is, if the sound is geting distorted by obstructions, it's gonna sound like crap.

I'm an analytical person by nature and I'm all for calculations and graphs. But this isn't a physics lab and ultimately, the way the system sounds is the final test.

In my experience, door-mounted speakers sound like utter trash. My objections (body buffeting the sound, dependency on windows to reflect remaining sound, etc.) haven't been answered.

I recently put a set of 3.5" mid cones in the dash with the tweeters mounted right at the corners of the headliner. It sounds amazing.

If someone is desiging a system for SQ then they won't be placing bears in front of speakers in the first place. If you just want something that will play, then of course...mount your speakers on the headliner and in your dash which wil give you the most uneven horrible soundstage ever. The whole purpose is explained in the post above. In a properly set up car, I should be able to lean to one side and still not be able to tell the sound is coming from a certain side, but to sound as if the singer/band is sitting right on the hood of the car singing at me and the music just fills the car. The way you have yours set up tells me that you know nothing about volume attenuation and you have never heard a car that had a good SQ system.
