Beovox S55 Passive Loudspeakers

BeoVox Loudspeaker

Production: 1981 - 03/1987

Continuing the range of Beovox ‘S’ range loudspeakers was the medium sized S55 which could either be set upon its own optional floor stand else it could be accommodated within a shelving system.

Comprising three drivers - a 210mm woofer, 115mm mid-range and a 25mm dome tweeter - the loudspeaker could deal with up to 55W RMS power although like most others in the range were fitted with an overload circuitry with reset button on the front of the speaker in between the two loose-fit panels.

With a choice of music centres to choose from with which to power it, the Beovox S55 was well-suited for either the Beocenter 5000 or 7002 and even the Beosystem 5000 (see image below).

There was a DIN connector fitted at the speaker’s rear and its stands could be angle-adjusted.  A range of colour finishes was available including oak and white.

The price of the Beovox S55 loudspeakers at time of release was £199 per pair.
