Manufactured: 1979 - 1983

Designer: Jacob Jensen

When B&O's engineers had discovered that the signals from respectively the bass unit and the tweeter in a loudspeaker do not reach the human ear at the same time, and that as a consequence a very slight distortion occurs, they asked Jacob Jensen to design a loudspeaker cabinet in which the units were skewed in relation to each other.

Jensen illustrated B&O's technical discovery with an angle: "form follows function". B&O's loudspeakers in this way achieved a characteristic visual identity in the 1970s and 1980s." - taken from 'Jacob Jensen' by Christain Holmsted Olesen.

Although the speaker was the tallest in the original line-up of aluminium compact passive speakers, Beovox C75 was no taller than an LP record, yet its reproduction quality equalled some of the full-size Beovox models. The one-piece aluminium log-line casing and separate bass (2 x 10cm bass drivers) and treble drivers (1 x 2,5cm) were specially designed to sound best in small rooms. Power handling was 75 watts RMS. Both the C75 and their smaller counterpart, the C40, benefited from the advantages of the "log line transmission system" and exploited the acoustic properties of small rooms to ensure well-balanced sound reproduction quality from these physically small cabinets.

As part of the Beovox Uni-Phase family, they also had linear phase and linear amplitude characteristics, which meant that they reproduced all types of music naturally. The range of C-type speakers won the ID Award in 1978.

Beovox C75 was eventually replaced by the CX100 in 1984.

Beovox C30 and C40 speakers were two compact bookshelf units offering high performance from deceptively small cabinets. The 10cm woofer and 2,5cm tweeter were mounted in thick aluminium casings to eliminate audible resonance. Log-line transmission ensured wide frequency response and clean, clear sound. Ideal for smaller rooms, their power handling capabilities were 30 watts and 40 watts RMS respectively.
