I have too much going on to continue to debate so I'll just concede. However, the fallacy in your post about what I have stated I saw is "assuming they point them toward the audience" -- they did not. Or rather they sort of did, but in the process pointed them at each other as well. Use them for larger groups as you will; properly set up they should be fine, but the real world does not always work that way. At least for me, and that was a good thing many years ago as bands would hire guys like me to make them sound better (then more often than not fire me after showing them how to do it). Oh, and acoustic mixing in a room tends to be decorrelated more than interference patterns directly in line with the speakers.

I'm not trying to debate you Don, just trying to understand what you mean by comb flitering in this context.

Multiple speakers with similar inputs and crossing wavefronts before and throughout the listening area. Depending upon the distance and frequency cancellations (or reinforcements) will occur. If they had not put the same signal into every speaker (four or five of them) it might not have been as noticeable... Picture a small group with four or five (they varied) speakers in a loose semicircle around the stage.

If an array is properly designed, none of this is a problem. Putting 4 or 5 speakers at random points and feeding them the same signal is not a proper array design.

A vertical array can be nearly constant bandwidth between two frequencies that depend on the length and the distance between the nearest drivers. Spacing probably does not want to be equal.

That was my point! As I hoped to make clear in my first post, not everyone understands how to use multiple arrays (among other things). Certainly some bands who buy them and slap them on a stage do not.

Using multiple arrays is not any more complex than using multiple speakers, of course they are just as prone to interference problems if not set up right.
