Is this, a Line array pretty much sounds like what ever it's drivers sound like in the first place.IOW, a bunch of vifa mids and tweeters are going to sound like a bunch of Vifa mids and tweeters.
And, a bunch of cheap drivers are gonna sound like a bunch of cheap drivers.
Yes, it may play louder with less distortion, and may image differently, but a duck is a duck is a duck.
IME, to get a REALLY good sounding Line Array takes really good drivers.
Actually, sometimes I think one might be better off builing a conventional speaker with really good drivers, rather then a line array with cheaper drivers, assuming the same budget.
If you think you can take a bunch of 50 cent drivers and see God by constructing a line array, fine.
But I will bet that if you took those same drivers, and made a smaller system out of them, the sound would be similar.\
Maybe it won't play as loud with as low distortion, and it will image different, but the sonic character of a speaker is determined by it's drivers, all things equal/
That is why guys like Rick Craig make Excelarrays, and use all out drivers.
