Direct radiator and horn loudspeakers present many different array problems. Some of these, such as the change in the directional radiation patterns as a function of size and frequency and the development of columar loudspeaker designs have received considerable attention in the literature. Others, however, such as the arraylike interaction of individual drivers in a single loudspeaker and the performance of large arrays of wide‐bandwidth loudspeaker systems have been given considerably less treatment. This paper will review these topics using array analysis considerations.
