For now I have only theoretical reasons.If to consider frequency range of the orchestra, we have highest levels in 500-1000Hz range and outside 250-4000Hz range levels drop 10db/octave.All major tones of most of the instruments are also in this range.So, the idea to keep this range as a whole without overlaying by different drivers looks very reasonable.When crossing at 1000Hz around this frequency we have two drivers playing same note of instrument which means we have 2 instruments instead of one.Outside 250-4000 range we have only harmonics and duplicating them is not a big problem, especially at -10db level.That is why my concept for now is to try to get this range as a whole.

Murat, I absolutely do not relate to your reason. In fact I think this is very artificially contrived rezoning. The true reason is that you like 555 driver that happens to go to 5K and you would like to sell to yourself some kind of theory around it. Let me to give you an argument from my strictly practical filed. In the scenario you proposed you will be having too much sound with identifiable location will be generated from location that will be too high. As the result you will be able to ingrate the sound from much greater region. Alternatively you might go do higher order of filtration but here is where the time consistency will go. Anyhow, it is not live sound but playback and to artificially map instruments to driver is a bit too unnecessary.
