Line Array Speakers
Line array speakers are designed to focus the sound into a very narrow pattern to avoid the wasted sound energy that comes from using standard speakers, This makes them extremely useful in large outdoor applications such as festivals and concerts.
Line array speakers are constructed of identical loudspeaker units mounted in a row and fed in-phase to create a singular sound source.
Line Array Systems
Used vertically, line array and mini line array systems give a narrow and defined vertical output with a wide horizontal spread, which is perfect at getting the sound across the audience rather than up into the ceiling or the open air.
When height or lack of fly rigging doesn't permit the line array to be suspended, they will typically be stacked on top of subwoofer units or on the stage itself using a custom framework.
