BeoLab 4 produces a sound quality that will add to any audio experience. Its dedicated PC mode makes it perfect as a computer speaker, as well as in a traditional stereo setup. BeoLab 4 is a true hi-fi loudspeaker, with the amplifier built into the loudspeaker unit and a range of Bang & Olufsen proprietary acoustic technologies ensuring the best performance. With three identical curved fabric-covered surfaces coming together at a round base, BeoLab 4 resembles a pyramid--allowing you to place it on a shelf, table, or in a bookcase. The ICEpower amplifier unit is a patented Bang & Olufsen solution, allowing for an ultra-compact design, high power output, and cool operation. Adaptive Bass Linearization offers superior bass performance from small loudspeaker cabinets. A switch with three bass settings, known as Adaptive Bass Control, ensures that BeoLab 4 always performs optimally, whether placed in a corner, against a wall, or on floor stands. BeoLab 4 has a tonal balance and sound pressure you won't find in other speakers of the same size.
