A loudspeaker horn has straight wall section and a curved wall section. The straight wall section has diverging walls defining a coverage angle and the curved wall portion is connected to the straight wall portion at a point tangent thereto, and has a proximal end disposed perpendicular to the plane of the throat entrance. At least one coverage angle in orthogonal planes has a common apex in the plane of the throat entrance and along the horn axis.
