Anyone knows at least a modicum of how line arrays work will laugh at these plots.
Meanwhile, have you wondered why other than in PA there are no speaker systems on the market which have more than one tweeter? (Unless they are in very large numbers and forms a CBT or Bessel array). If the manufacturer's "Quattro" array is their invention and we don't yet know how it operates I expected a patent or at least a paper reference. There is none.
Obviously they sound well as there are people testifying it, but why use smoke & mirrors? Why lower yourself to uneducated level?
