Beolab 4000

Squeeze a pair of BeoLab 4000s into the bookcase in your study and link them to the music system in the living room, via a BeoLink eye, which responds to your remote control. Fills the room with sound You can’t see sound, but that doesn’t mean that it has to be totally invisible. BeoLab 4000 is formed from aluminium that’s polished until it shines like a mirror. It also comes in an array of colours - not only to suit your interior decoration, but because life itself is full of colour. Aluminium Aluminium is the perfect material for BeoLab 4000. It’s light, but offers an impressive stiffness despite a thickness of only a few millimetres. It also makes it easier to obtain the loudspeaker’s unique curved form, which is important for avoiding problems with audible artifacts due to internal standing waves in the cabinet. Active loudspeaker The equation used to be a simple one; the louder the sound, the bigger the loudspeaker - but not anymore. Placing the amplifier directly into the loudspeaker allows us to reduce the overall size of the BeoLab 4000 to one third of a conventional loudspeaker with the same sound capacity. The cube During the development phase, all BeoLab loudspeakers are put through their paces in ‘the Cube’, Bang & Olufsen’s own acoustic measurement facility.In the 12 x 12 x 13 metre room, the entire audible spectrum is played through the loudspeaker to give a perfect picture of it’s sound ‘fingerprint’. Performance To ensure an optimal performance every time you listen to it, a BeoLab loudspeaker constantly fine-tunes the signal received from the sound source before distributing it out to the separate bass and treble power amplifiers. The listening panel Since it’s humans that will listen to BeoLab 4000, it’s important that a human ear should also measure its quality. That’s why Bang & Olufsen employs its own Listening Panel to scrutinise every step in a loudspeaker’s development. If any sonic shortcomings are discovered, the whole project is returned to the drawing board. Individual Calibration Since no two loudspeaker units have exactly the same physical characteristics, we calibrate them individually to make certain that the sound of each and every BeoLab 4000 loudspeaker leaving the factory is identical. Appearance Using aluminium for the cabinets is not just about looking good. Despite a thickness of only a few millimetres, it’s a remarkably strong metal that's easily shaped to eliminate the problems with audible artifacts due to internal standing waves in the cabinet. Flexibility in placement Use BeoLab 4000 as your main loudspeakers or as extras in a Bang & Olufsen surround-sound set-up. Their ability to fit into the smallest of spaces, or to be hung on the wall at almost any angle, also makes them the perfect loudspeaker for the BeoLink®system. BeoLab 4000 owes its shape to the fact that active loudspeakers produce heat if they have to play for a long time without a pause. Squeeze it into a bookcase and it will still have sufficient cooling air around it, no matter how many books it shares its space with. Raised on the optional stand, BeoLab 4000 presents itself at the same angle as BeoSound Ouverture.
