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.
