Ok, here's the scenario: A big, traditional array of boxes, like Yorkville TX, or EAW KF850, with ground-stacked sub horns like LAB horns.

I'm going to say the same thing as Peter (M.) from down under. In a large array of something like the EAW 850, or the nexo B1, the undersized low mid horns couple effectively. This along with the additional directivity of the array, often results in TOO much energy in the region you are talking about.
This is the classic low mid "mud" that has largely gone the way of the dodo thanks to careful design of line arrays. The dedicated processing of the 850/alpha-type boxes can have substantial cuts in eq for this range to sound balanced.
If you look at the raw frequency response of many of the line arrays (EAW 730 for example), you will see an upward tilt in response from lows to highs. This is intentional so that the boxes, when coupled together, provide flat response through the low mids.
If you go to meyers website, and read the paper on their LD3 line driver, is covers this kind of low mid eq very effectively.
