Abstract

A loudspeaker system with an endfire array of three or more loudspeakers (Z n, n = 3, 4,..N) arranged on a line. The system has a set of filters (Fn, n = 3, 4,..N), each loudspeaker (Zn) being connected to one corresponding filter (Fn). The filters (Fn) are super resolution beamforming filters such as to provide the endfire array with a pre- designed directivity index (DI) and a pre-designed noise sensitivity (NS).
