You are about as worthless as worthless gets. I don't have to explain Jack to your stupid ***. I will pay for you to fly to me and say the **** to my face. LOL And while your here I'll let you listen to my Home theater and cars. And show you what sounds good. "
So in layman's terms, you have no clue about the subject nor the intelligence to learn anything either, LOL...
How is someone supposed to NOT take that statement personally?I'll admit that it seems like you know a fair bit about the subject. I don't think you know as much as you THINK you know, but it seems like you have some experience. Here's some advice, and I'm about the billionth person to say this: you REALLY need to find a way to provide your opinions constructively without being so rude.
Seeing how these are the very first things that disappear to supposedly UPGRADE the audio system is a dead giveaway absolutely nobody has a clue around here what they do and why. Now, here is an idea, before spending money and ask others for truly worthless advice, read up a bit on the subject and follow some installs that make use of the science that has always been behind audio field, this includes the function of center channel. While you are at it, read up on panned mono and what a listening "sweet spot" is. I gotta say, chances of anyone understanding what they do around here are none.

The Best of Corvette for Corvette Enthusiasts
Here's what you are missing Pete, I agree with you because I've built the stereo you are describing. Still you have made me want to hate you.
You can improve the experience of your stereo several orders of magnitude just by placing the existing speakers optimally. You can improve the experience of your stereo incrementally by replacing your speakers with higher quality drivers.
8" Bose drivers vs smaller drivers. I don't know much about the Bose drivers themselves, however I do know poor quality 8" drivers can be out done pretty easily by smaller drivers (especially 3way component drivers/not coaxial).
I'm a firm believer in speaker specialization. You can't tell me an 8" paper is going to do a better job reproducing highs than 1" titanium, any more than a tweeter than generate the sounds of a kick drum.
Most people believe sound quality improvement is the bass thump and some will enjoy a crisp high hat. Very few will enjoy an expansive stage or vocal clarity. So answer the question that was asked: will it sound better (bass)? Maybe.
With bass, It's all about air movement and cone flex. Stiffer cones with long throws can provide before defined sound than weak cones with short throws. So pick the largest size that'll fit and find a speaker with a long throw and high sensitivity.

With that said, the higher the frequency reproduced, the less energy will be required to produce the sound and thus smaller driver will be needed. Ironically enough, paper cone is considered one of the best around and is present in many very expensive speakers. Kevlar reinforced paper can be found in some of the best subwoofers out there. OEM use paper cone drivers because they are cheap and have very high sensitivity allowing them to use low power amplifiers with a caviot of cheap suspension limiting their output abilities. None of this has anything to do with why I recommend not messing with the stock system. Also, you can stuff a small tweeter in the door and generate more highs due to smaller diameter driver better off axis dispersion but the highs will be generated at the knee level and you will hear them coming from there due to height cues at higher freqs. When you combine this with elimination of the center channel instead of improving it, you end up with worse sound than OEM, this is a fact.
The speakers are aimed at each other creating panned mono btw, not stereo, this is why the center channel is there, to reduce the off center listening position and to raise the stage. Absolutely nobody around here has a clue what they are doing.

Also, in corvette, the woofer does not play the highs, the small coaxials do, thus, the upper end appears to be week due to off axis rolloff that takes place about 10k. The real fix would be to put tweeters in the pillars or dash and lo pass the door coaxials limiting them to midrange only. The center channels should be maintained even then. This is not magic or art, simple physics and acoustics instead.

Sound stage does not equal sound quality. It is similar to sound experience. Please split the two concepts. What they are interested in is enhanced enjoyment, not proper positioning of the sound stage.
Something you have to understand is what you read about in magazines is not neccisarily the same as what people naturally want.
They also do NOT want faithful reproduction of sound (is flat eq). They want the reverse bell curve. So don't try to flatten it.
Your ears are located between the doors, so it is still stereo. However without a time delay circuit or improved placement the audio from your side speakers will reach your ear sooner. Most people won't recognize the difference.
The number one thing new speakers will do is change the way the eq curve. People will recognize it as different and probably better. Bose company is known for putting most of their money into marketing, so I would expect any new speakers would sounds more pleasing.
I want to flip the table on you. Please describe the car or cars in which you have modified your stereo. What have you done, placement and brand. And photos.
The one thing I've learned as an lead engineer is things that work in paper or on the bench almost always fail when deployed in the real world.
In regards to your last paragraph. I have my 1" MB Quart Qs mounted in my a pillar. It does raise the soundstage but at the cost of being disparate from the 3" and 6" drivers I have in the door. The result is the soundstage moving when highs are not being used. The optimum placement is on the floor as far back as you can. This way the sound from the right & left reaches your ear at the same time. The problem of course is your wet/dirty shoes will eventually destroy the cones and the simple fact that nothing fits down there.
