[QUOTE="Bennett Prescott, post: 107104, member: 4"] Re: Line arrays and inter-element angles. A topic near and dear to my heart. Personally, I prefer a smooth coverage transition, building an array more like a spiral or exponential array as you personally prefer. I like to think in terms of using half the array for the back half of the audience, the next 1/4 for the nearer 1/4 of the audience, etc. This tends to line up relatively well with doubling boxes for doubling throw. I have never, ever, found any application where using the zero degree angle was useful. Even for very long throw audio (800'+) I found it causes more lobing problems than it helped get energy out there, by the time you're at 300' or so you have to give up on a lot of HF anyway and the environment becomes a serious issue. At that kind of distance 1° is plenty tight. All line arrays enclosures are designed with a certain wavefront curvature, taking it into account will produce the smoothest results. Another issue is that neither line arrays nor humans are point sources, but it is easy to read the modeling software like we are. Just because your array can produce a really sharp cutoff and put a beam of energy right where you want it doesn't mean it will be experienced well by the time it gets there. If the difference between a 6' person and a 5'4" person can mess up your model it's time to reconsider your goals. High hung arrays are really great for the far seats, but the front section of the audience starts to be really off axis. Just like it's hard to get a sub array to cover a very wide room, it's hard to get a line array to have consistent coverage down close.

I like to lean on fills as well, but not flown ones. I generally try and cover 80% of the audience with the arrays, and get the front 20% with some other method. YMMV, take what I say with a grain of salt since it's been at least a year since I've flown anything at this point. [/QUOTE]
