Quote "I guess another way to ask this is, does the horn affect the upper freq limit for which proper coupling will occurr to become a 'line array'."In a one word answer yes. NOW since you have asked the right question lets closer examine the line array marketing hype of todays systems.A huge amount of manufactors offering line array systems for both consumer and pro are neglecting to specifie weather or not these systems meet the criteria for operation as a line array system thru the entire frequency bandwidth. As you have so intelligently questioned the center to center spacing of the horns and there application in line array, the following answers may not come as a surprise to you.Becase of horn dimensions and physical driver sizes the high frequency information becomes the hardest information to configure into the mathmatical terms that constitute a line array .This is due to the spacing of the componets as you have questioned.The manufactors of some of these systems are not telling you that after a certain frequency these systems react as point source in the high frequency information because of the componet spacing limitations.They are just jumping on the fad of the week to sell product.I am aware of only two systems in pro applications that meet the mathmatical criteria for a full bandwidth line array system.One is a ribbon tweeter horn device and the other is a patented wave guide device(I really dislike use of the terminology "wave guide" That term was originally applied to higher frequency use and not audio applications)Other criteria apply.
