One uses polar plots to describe the behavior of conventional speakers such as constant directivity horns or small arrays built up using smaller transducers. Line arrays produce cylindrical waves in the near field and therefore, the vertical polar plots change as a function of distance. To describe the vertical radiation of a line array an industry accepted method is to use validated modeling programs and paint a picture of the radiation as a function of distance. This paper addresses the radiation characteristics of the MA12 and in addition shows measured polar plots, on-axis frequency response, controller curves, and impedance curves.
