Loudspeaker Arrays and the Product Theorem

When an array of identical loudspeakers is constructed, the composite directivity pattern is determined by the directional characteristics of the array as well as the inherent directivity of the loudspeakers. The relationship between these directivities is given by the product theorem, which states that the overall directivity of an array of identical sources is the product
