AB  - An endfire loudspeaker array that radiates sound in the direction of the axis on which the loudspeakers are placed offers an alternative configuration for creating narrow spatial beamwidths. The basic theory of such arrays was investigated in a parametric study that explored the influence of the number of loudspeakers, their spacing, the length of the array, and the stability of the signal processing algorithm to create optimal beams. A prototype system was tested by simulation and measurement to confirm the parametric analysis. When the directional patterns of the individual loudspeakers were taken into account, the resulting directionality index improved by 3 dB.
