[QUOTE="Phil Graham, post: 107139, member: 430"] Re: Line arrays and inter-element angles. This is the most reasonable goal, in my opinion. It is important to remember that the most even coverage volume front to back is a consequence of the highest level of intra-array cancellation in the nearfield. A finite line source, when far enough in the far field, behaves as a point source. Near the array, the evenness in amplitude is due to the increasingly incoherent summation of the array elements. This is a useful effect, but it has limitations on how far you can rely on it. Also, if you work too hard in getting the maximum horsepower at the back of the space, you'll find that the down lobes are causing serious issues at points within the primary audience area. Ideally you can configure the array to scuttle the down lobes in a region where the audience is not present, Not usually possible, but an interesting target goal to aim for. [/QUOTE]
