Abstract
A loudspeaker in which a plurality of speaker drivers is jointly tasked with reproducing sounds. The plurality of speaker drivers is arranged on the loudspeaker so as to achieve a desired sound effect at a listening position. The plurality of speaker drivers is arranged in an arcuate arrangement or in a sinusoidal arrangement. The desired sound effect may be facilitated or enhanced by modifying the timing of sounds emanated from each of the plurality of speaker drivers. Alternatively, sounds may be sent to each of the plurality of speaker drivers substantially simultaneously. The sound effect achieved may be a time-alignment effect such that the sound arriving at the listening position is time-aligned to maximize constructive interference between the various speaker drivers of the plurality of speaker drivers. Alternatively, the sound effect achieved by other implementations may be a progressive kick in sound waves moving along the arcuate or sinusoidal arrangement.
