just to clear something up about coverage, technically every speaker in the world had a 360 degree coverage, what you need to know is the full story, for example
maybe
0-50 degree coverage, 123 db, 50-15k +/-3db
51-75 coverage, 118 db, 50-9k +/-6db
76-125 coverage, 112 db, 50-5k +/-10db
126-175 coverage, 90 db, 50-1k +/-15db
etc, not one of these companies can or will give you those kind of specs, because #1 they don't want to look bad if there's doesn't look good, and #2 it's pretty much impossible unless your outside with no walls for anything to bounce back at you
so please, listen and if it sounds good, that the first thing, then everything else.
