ABSTRACT:
A sound delivery system comprises at least one elongated speaker mounting element. A multiplicity of individual speakers are mounted in the mounting element to form a linear array of speakers with each speaker being adapted to radiate sound in a direction transverse to the array. The number of speakers and the spacing between them are selected so as to focus the sound emanated by the speakers by reducing dispersion of sound in the direction of the linear array. A device is also included for coupling audio signals to the speakers.
