Abstract (en)
[origin: WO2008010086A2] A loudspeaker system includes at least two stand-alone multiple loudspeaker devices (1L, 1R), each comprising a frame (3) with a horizontally oriented array (5) of first loudspeakers (7) for reproducing sound in a higher frequency range The system further includes a second loudspeaker (11) for reproducing sound in a lower frequency range, the frequency ranges having a crossover frequency f<SUB>c</SUB> The first loudspeakers each have a first radiation surface (9) of maximal 1000 mm<SUP>2</SUP> and the second loudspeaker has a second radiation surface (13) In each device (1L, 1R) a central area (9a) of each first radiation surface being situated at a vertical distance d, from a central area (13a) of the second radiation surface wherein 750 Hz =f<SUB>c</SUB> =3000 Hz and d =2.? f<SUB>c</SUB>, wherein ? f<SUB>c</SUB> is the wavelength of the reproduced sound at the crossover frequency and wherein d is minimal 75 mm and maximal 3000 mm The system also includes a means for processing an audio content signal to generate individual signals for input to the first loudspeakers resulting, during use of the system, in a directional acoustic signal of the array of first loudspeakers of each de\ ice This system is able to reproduce sound of high fidelity qualification
