What I'm referencing is having the center pair's capsules and each side of the flanking pair's capsules so that the line between the center and flank is at a 90 degree angle to the intended prodominant sound source (in most of our cases, PA stacks). So that you get image smear for surrounding details (which can be good or bad), but the stacks should have less comb filtering on the final mix down. I drew a picture that I'll post this evening that illustrates it.
So is what you're doing wrong? I wouldn't say so, and whether to change largely depends on what you value. If it sounds good to you, I wouldn't sweat it, but it wouldn't hurt to try on an evening when you can play around.
right as I hit post: hi-lo beat me to it.

OK, yes, I can visualize that.
How would it work with a large acoustic ensemble with spread sound sources?
In my most recent, the array was about 6 feet behind the conductor (symphonic band) and 6 feet over his head.
The organ pipes were split L/R outside the stage.
Thanks
