Not sure this is the right forum section or even the right name for the speaker setup, but would a large array of maybe 12 pcs of 5" coaxial car speaker have any chance of sounding good? Whats the disadvantages? There will probably be a subwoofer the extend the systems LF.
The drivers I have in mind are these:

why a line array?
As a qualifyer, I 'm personally not a fan of arrays. I guess I just don't get it.
What I did was to mount a set of JBL "GTO 525" (similar to the Monacors in your link) co-axials into an 11 litre box I had kicking around. They sound quite good, much better than I could have imagined. I believe simpler is better. Add a sub and the required xover/amp system and you'd be in business.
To me the idea of creating sound from something other than a point source is "backwards", although good examples of line arrays have been built. Many loudspeaker manufacterers have spent a great deal of time, energy and money trying to get to the point source ideal.

Here is a very unusual looking car hifi dual cone (the most extreme ratio i have seen yet). But I don`t think it makes more bass than a long-throw round 4" like Tangband or so.

Well I don't have a link to Dr. Griffin's white paper on line arrays handy, but you really need to read it if you're serious about building some. I'm sure someone will post the link.
From what I remember, a coaxial driver won't work because the center-to-center spacing has to be less than one wavelength in order to avoid comb lines which disrupt the effect of a single large point source that is the whole appeal of arrays. Even if you mounted the coaxials with the frames touching, you would lose the desired effect above the frequency whose wavelength is equal to the width of the frame.
On the other hand, I have not seen an auto sound coaxial yet which you could not remove the tweeter from. You might need to get very creative in mounting the separated tweeters to a baffle, but it would be one way to get the results you hope for with the drivers you proposed.
