[QUOTE="Ivan Beaver, post: 108824, member: 30"] Re: Quick and Dirty Bar Rig Speaker Pattern Poll The big problem is that the rated coverage pattern only applied to the top 2-3 octaves because the horns are so small. So what you "think" the speakers are doing is quite different from what they really are. But if I was to choose a "general pattern for most applications" it would be around 80-90°. In many cases it is better to have energy hitting the walls than to not have enough coverage pattern-in my opinion. And when people make statements that they use narrower patterns to "keep the energy off the walls" it is-again' only the top octaves in many cases-especially in "bar band" system that uses small horns. The only way to have pattern control is PHYSICAL SiZE-there is no other way around that. Small devices simply don't have enough physical size to have control. And for a given physical size-the wider pattern will be able to control the sound to a lower freq. So a physically smaller horn that has a wider pattern will be able to control as well as a larger narrower horn. And then we run into the whole "How smooth is the coverage within the pattern-things like hot spots etc" but we won't go there. As with all audio question you HAVE to ask "At what freq". The pattern could be completely different at a different freq-so how much energy is going where now? [/QUOTE]
