Bang & Olufsen - Beolab 4000 Speaker set

The Bang & Olufsen Beolab 4000 is a premium active bookshelf- and wall-mounted loudspeaker with a timeless, teardrop-shaped design by David Lewis. Thanks to the built-in amplifiers (Active Loudspeaker Technology), this compact speaker delivers an impressive, expansive and deep hi-fi sound. The polished aluminum enclosure is designed to dissipate heat extremely efficiently and to eliminate vibrations, allowing it to be mounted horizontally or vertically on a wall, in a cabinet, or on a stand.

Specifications:
Frequency Range: 55 Hz – 20,000 Hz
