BeoLab 3 was a very small and compact active speaker which delivered sound which belied its size. Producing 250 watts of excellent quality sound the speakers could be combined with a BeoLab 2 active sub-woofer to produce sufficient noise to fill most rooms. BeoLab 3 could be positioned on a wall,a shelf or on its special floor stands. The unique Acoustic Lens Technology, also found on the top-of-the-range BeoLab 5, allowed for freedom of placement without loss of acoustic quality. The equal dispersion of high-frequency sound in a 180° arc meant that the sound experience was excellent in any listening position. Additionally, as the acoustic lens limited sound reflections from the floor and ceiling, the lens also ensured a consistent and precise sound experience. The new technologies in BeoLab 3 produced impressive results with most modern Bang & Olufsen music systems able to accommodate the speakers.
Looking similar to the BeoLab 2 sub-woofer, Beolab 3 also had a close connection style-wise with the Beovox 2500 ‘Cube’ speakers of the late 1960s.
Within each unit was fitted a 101mm woofer, a 19mm tweeter and two passive bass radiators of 101mm. To produce its remarkable sound the BeoLab 3 used two class ‘D’ amplifiers rated at 125 watts each. The speakers had three pre-set bass settings for placement in a corner, against a wall, or freestanding in a room. This was made possible through Adaptive Bass Control technology, exclusive to Bang & Olufsen.
The two ICEpower amplifiers in each BeoLab 3 produced very little excess heat, so there was no need for the cooling space often necessary with traditional active loudspeaker construction. A conventional speaker would have to be around ten times the size of BeoLab 3 to deliver a comparable sound.
BeoLab 3 was sold with a black rubber foot for positioning on a flat base and the whole shell of the speaker was manufactured from solid aluminium. Produced in its early life just in black, a choice of colours was later offered (see below). A glossy white was introduced at the end of 2008.
A single Power Link socket was fitted to each BeoLab 3; if coupled to a non-Bang & Olufsen audio system a converter cable could be used to connect at line level. Five metres of special Power Link cable was delivered with each BeoLab 3 sold.
