Ritteri...It's a bit hard to follow your logic. Your analogy to a violin, where the wood body is what makes the sound, is one that I might use to explain the function of the sound board in a piano.
Your preference for cone drivers in boxes is just your opinion. Others may disagree.
The idea of installing a small driver in an actual violin body has long interested me, but I haven't got around to doing it yet. Do you have any spare old violins kicking around?
And Tubegroover...I may be a "skeptic" but after rendering my opinion I often go away quietly and do some experimentation. A "crackpot" idea sometimes leads to something good, even if the original idea isn't. My "skinny wire for tweeters" biwire scheme is an example...IMHO.
