ABSTRACT:
A loudspeaker combination comprising a plurality of sections of dynamic loudspeakers which are arranged adjacent each other in substantially one continuous plane. A number of these sections can be muted at increasing frequency under the influence of a low-pass filter. All loudspeaker sections are connected in series with each other and each mutable loudspeaker section is shunted by a capacitor. Each low-pass filter is constituted by the impedance of a mutable loudspeaker section with the associated capacitor. One loudspeaker section is not shunted by a capacitor and comprises at least two loudspeakers with the axes of the loudspeakers diverging relative to each other. This has the advantage that the loudspeaker combination has a virtually constant angle of aperture over a wide frequency range.
