A loudspeaker includes a frame, a magnet coupled to the frame and a diaphragm secured to the frame. An acoustic lens may be positioned in front of the diaphragm. An aperture extends through the acoustic lens. The acoustical directivity pattern of the loudspeaker may be modified by the acoustic lens to improve the uniformity of the off axis vs. on axis sound pressure level.
