Description
Product Overview
Designed as one of Bang & Olufsen's compact active loudspeakers, the BeoLab 4000 combines a small footprint with a distinctive curved enclosure. Its cabinet incorporates a bass-reflex acoustic design and a 2-way driver arrangement consisting of an approximately 11 cm woofer and 1.8 cm tweeter. Published specifications list an effective frequency range of approximately 55 Hz to 20 kHz. The rear panel visible in the photographs includes two Power Link connections, a line input connection and the Left/Right/Line operating selection. This allows the speaker to be used within compatible Bang & Olufsen systems or through a suitable line-level setup. The black cabinet and curved profile are characteristic of the BeoLab 4000 design. The unit photographed shows signs of previous use, including marks and surface wear on the glossy front section and minor wear around the cabinet and grille. Meltron ESingle Speed Full Track MonoFunctional operation has not been verified from the photographs. Buyers should consider the unit a vintage/collector example unless operational testing is separately confirmed.
