AB  - Loudspeakers with variable directivity offer the potential for improved sound reproduction quality in rooms by reducing sound reflections from walls, providing better reconstruction of the desired sound field than an equivalent array of monopole loudspeakers and by allowing optimum active compensation of reverberation. This paper discusses the design of a variable directivity loudspeaker array for 2D surround reproduction. The loudspeaker uses fifteen drivers in a circular array and Fourier beam-forming to generate up to third order responses in azimuth. Azimuthal and vertical polar responses are presented which quantify the performance of the loudspeaker.
