Abstract:
1. A mid-range loudspeaker array having a frequency range from substantially 250 Hz to substantially 8 KHZ, said loudspeaker array comprising at least one line source, said at least one line source comprising a curved one dimensional array of loudspeakers, each of which comprise a cone diaphragm driver and has a dispersion pattern angle of less than 60° in a plane which is perpendicular to a one dimension of said one dimensional array at said loudspeaker, said loudspeakers having propagation axes in a common plane which, in use, is vertical, each adjacent pair of said loudspeakers of each said line source being physically time-aligned in a direction bisecting said propagation axes of said loudspeakers of said adjacent pair, said propagation axes of said loudspeakers of said adjacent pairs in at least part of each said line source subtending an angle greater than 0°, said propagation axes of said loudspeakers of each said adjacent pair in each said line source subtending an angle of less than or substantially equal to 10°.
