So in many threads it is advised against putting two combos or two cabs side-by-side on a stage/floor/ playing space etc. because the speakers have a cancelling effect on each other sonically for certain wavelengths. Yet when you look at a lot of cabs and combos with multiple speakers of the same size in them, the speakers are often paired side-by-side. For example, let's say a a 6x10 cab. Three rows of two speakers, stacked yes, but three rows of side-by-side. Do the makers just say " to heck with the specs and rules.......this is the way we make that cab for space-saving reasons" Do they factor in the side-by-side effect? Is there any effect difference in paired side-by-side speakers in a cab or combo sonically, spec-wise or any other way compared to ones that aren't? Does it even matter?....Is it all just a myth?
