The Line Array Systems is a loudspeaker system. They are basically made up of number of identical loudspeaker that are mounted in a line & fed in phase. This type of set up create a line source of sound. Apart from this the distance between two drivers is kept minimum so that they can constructively interfere accordingly and send sound waves to the maximum distance when compared with traditional horn loudspeakers. They can construct sound pattern more evenly with distributed sound output.
