[QUOTE="drew gandy, post: 108048, member: 880"] Re: tall skinny speakers I want to make a comment on this and some things mentioned a few posts back (perhaps expanding on what Ivan was saying). Unless there is some special acoustic process at work here that is not being divulged, these skinny speakers are basically 360 degrees in the horizontal below around 800-1Khz and probably don't narrow to 180 till you get up around an octave higher. This is why you hear so much onstage. That may or may not be a good thing. It sounds like it's been a good thing for Gene so far for his simplified monitor arrangement but I will suggest that outside gigs are likely the most forgiving of the uneven patterns. By comparison, a typical 12" with horn box will still have about 180 degrees of width down to around 500-600hz but eventually go omni as well as the frequency drops.
