<p>Loudspeaker in a single cabinet arranged for wall mounting. The loudspeaker has two dipole loudspeaker units spaced apart and arranged to generate respective acoustic dipole signals. Reflectors, such as plane surfaces, are arranged to reflect sound from the respective dipole loudspeaker units. The reflectors and the dipole loudspeaker units are arranged such in relation to the cabinet that sound from one side of their diaphragms is directed substantially parallel with the wall and away from the cabinet, preferably to the sides. Sound from the opposite side of the diaphragms is directed substantially perpendicular to the wall and away from the wall. Such loudspeaker is suited in versions as a stereo sound bar, e.g. placed under a flat screen TV set. The loudspeaker provides a wide stereo image which can be experienced in a large area in a normal room due to reflections from side walls, and still the loudspeaker produced a stable centre image. The dipole units may be implemented as two-way systems, and a centrally placed woofer may be included to reproduce low frequency audio components in mono.</p> |
