This is a board specifically for those who want to use line arrays. Why are you trolling the board with your views? Why don't you go to one of the audio boards which has your view?

Why bother wasting your time being a troll here?

Just FYI, assuming that you are not a troll, and really want to know: reasons:

1. Higher sound pressure levels,
2. reduction of distortion as power is dispersed among several drivers,
3. higher power handling attained,
4. much widers sound stage,
5. near constant sound levels throughout the listening room,
6. an image sweet area as opposed to a sweet spot,
6. much much greater dynamic level recreating the live event much more effectively.

And if, as in proaudio, you use electrical crossovers and separate amps the for mid/woofer array, the tweeter array, and the subwoofer, you will hear something really spectacularly like the real performance, and very much different than a single spot speaker.

I suggest that you go to James R. Griffin (PHD)'s white paper on "design guidelines for practical near field arrays".
