Niski i srednji ne slabe toliko, tj. ne upija ih publika, a visoki su rasporedjeni po publici ravnomerno, da ovima iz prvih redova ne probija usi.

A line array is a loudspeaker system that is made up of a number of loudspeaker elements coupled together in a line segment to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded loudspeakers, and with a more evenly distributed sound output pattern.
