Beovox 5700 high fidelity loudspeaker was of studio monitor quality with minimum distortion and maximum power handling capacity.
The loudspeaker was designed to handle 60 watts RMS or 100 watts music power with a distortion of less than 1% over the entire frequency range of 25-20,000 Hz. In order to produce these qualities, Beovox 5700 was fitted with a 25cm ABR (Auxiliary Bass Radiator) unit and a 25cm bass unit which together produced a clear powerful bass reproduction. Its mid-range dome was 5,5cm in diameter and its dome tweeter was 2cm. Dispersion was 160 degrees.
Owing to its size, Beovox 5700 could be preferably used as floor-standing speakers. For this reason Bang & Olufsen designed the trumpet stand, type 8906007. This stand had a top on which the loudspeaker could be placed, not only elegantly, but also practically so that a good sound dispersion could be achieved.
Beovox 5700 could be used with Beosystem 4000, an uncompromising stereo system, top of its range in the mid-1970s.
