[QUOTE="Max Warasila, post: 113090, member: 3845"] Re: Mini Line Array With only two speakers, that doesn't qualify as a "line array." The theoretical idea behind line arrays is that (assuming your line array is infinitely long), you will have a cylindrical wavefront rather than a spherical one, causing a 3dB loss in sound rather than a 6dB loss with point sources. [I]In the real world[/I], however, what makes a line array useful is variable coverage control, lower distortion in drivers due to proper coupling, etc. For this to occur properly, you need a certain amount of length, and some serious knowledge of how to deploy one correctly, because there's a bit of crazy physics between all the interacting parts which can be difficult to understand and work with. Not to mention, for anything below the HF range, pattern control in the vertical axis [I]requires[/I] a longer line array, similar to the way that lower pattern control in horns requires a bigger horn- simply because of the size of the waves. Also, more boxes does not immediately mean louder sound. All it means is more sound coming from more sources- which can work for or against you. To get them to work correctly, they are going to have to be able to work together, by "coupling," something I don't really have the knowledge to explain much further. Just don't assume that more boxes is going to get you louder sound.

Point and case here- I'd work on getting some systems that you can use at your big events, but you can somehow dumb down for your smaller events.
