Abstract
A line array speaker provides highly uniform frequency response throughout a wide listening field, while also reducing distortion and improving fidelity, clarity, and output level. In a symmetrical embodiment, central apertures are straddled by a sequential pairs of sets of apertures. The straddling pairs emit frequencies in the next lower frequency band relative to the frequency band of the immediately preceding frequency band apertures. In an asymmetrical embodiment, sequential frequency bands are emitted by adjacent sets of apertures rather than straddling pairs of sets of apertures. Each of the apertures may be a loudspeaker cone, one or more straight slots, one or more arbitrarily curved slots, one or more arbitrarily angled slots, one or more holes or the mouth of a horn. The speaker may have a front baffle which is a flat panel or multiple facets arranged in one or multiple recesses across a front of the speaker.
