Duke, I realize you are not saying that horns "beam" when you mention "radiation pattern control", but that and other comments here seem to imply that a very limited sweet spot is produced by horn systems.
Admitting my own experience with horn systems is limited, I question this condition. I own a pair of rear loaded horns (C&C BEN) which may not qualify but a good friend first had AG Unos and now AG Duos. I believe his room is 20' wide with the Duos spaced by 10-11' with moderate toe-in. I can sit directly in front of one speaker and still hear a defined stereo image spread. This is not to suggest there is not a more precise soundstage presentation when seated in the middle sweet spot but in his room/set up I find his horns to present at least as wide of a good listening area as any box system I've heard in that room. Perhaps this is aided by the 4-5' separation from the side walls (a point which seems contrary to some other comments on horn systems).
If you would comment further it would be appreciated.
