LOUDSPEAKER SYSTEM AND LOUDSPEAKER HAVING A TWEETER ARRAY
摘要
.A loudspeaker system includes at least two stand-alone loudspeaker devices (1L, 1R) each comprising a frame (3) provided with a vertically oriented array (5) of first loudspeakers (7) for reproducing sound in a higher frequency range. The system further includes a second loudspeaker (13) for reproducing sound in a lower frequency range, wherein the frequency ranges have a crossover frequency between 750 Hz and 3000 Hz. The first loudspeakers each have a first radiation surface (9) in each array a central area (9a) of each first radiation surface being situated at a distance d from the central area of neighboring first radiation surface, wherein the wavelength of the reproduced sound at the crossover frequency is shorter than the distance d, which itself is below 1 meter. The system is able to reproduce sound of high fidelity qualification.
