Living proof that big sound need not take up more space than a couple of ring binders, Beovox CX50 snuggled in anywhere, even as extras in a Beolink® system.
Beovox CX50 and Beovox CX100 loudspeakers were the smallest loudspeakers from Bang & Olufsen up to the time that the manufacture of passive speakers ceased in 2002. They were mostly used to place within a passive Beolink® system (MCL), although they could also be used as main speakers. Thanks to different colour combinations they blended well into most people’s décor.
Beovox CX100 finally ceased production in September 2003 – the last of a long and successful line of passive speakers.
Passive loudspeaker, aluminium cabinet, available in black, white and brushed aluminium.
Replacement drive units: Top drive unit for CX50/CX100 Part number: 411743
BeoVox CX50/CX100 replaced C40 and was designed to be optionally mounted with the wall brackets supplied in the box.
Dimensions 12 x 32 x 20.5cm/5kg
Cabinet Finish Black/White/Aluminium
Long Time Power Output per Channel 100 Watts
Max Sound Pressure Level 89 dB

Beovox Cona functioned almost like a prompter who ensured that the sound didn’t forget its ‘lines’. It worked on the principle that the human ear cannot detect in which direction deep tones are coming from. Beovox Cona, like the newer BeoLab 2, could therefore be placed anywhere in a room with the rest of the music system to give it a deeper, much richer sound.

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.

In 1972 the Museum of Modern Art in New York (MoMA) chose seven Bang & Olufsen products designed by Jacob Jensen to be included in their Design Collection as representing excellent examples of the Museum’s criteria for quality and historical importance; design, in fact, which had influenced the twentieth century. Beovox 2700 were one of those seven products. That same year Beovox 2700 won the iF Design Award.

Beovox 2500 Type 6211 were ‘cube tweeter’ speakers, launched at the same time as the innovative BeoLab 5000. The Beovox 2500 Cube loudspeakers were developed to complement both the Beomaster 5000 and BeoLab 5000 in order to spread the high tones. For decades, controlling the directivity and dispersion of particularly the higher frequencies has been a key concern for loudspeaker designers worldwide.
The ability to control the higher frequencies is crucial, as they carry the majority of sonic information about what you are listening to, and where the sound is coming from. During the 1960s, Bang & Olufsen’s Acoustic Engineers were just as concerned with creating a “quality stereo” experience. Whereas it did not matter just how bass frequencies were distributed (as the human ear cannot differentiate the direction of low frequencies) the problem of ensuring good dispersion of midrange and treble frequencies has always persisted.
The problem back then was the same as today; whereas there is no directional problem with the bass, how to ensure dispersion of the midrange and treble? The focus was on the treble, as the higher the frequency range, the narrower the field of dispersion. Beovox 2500 Cube, released in 1967, was an attempt at an omni-directional treble loudspeaker, where the six driver units in the cube-shaped cabinet overlapped to cover all fields. The six driver units, one on each face of the cube, presented a rather special placement problem, which was solved by balancing the loudspeaker on one of the corners. It could therefore rest on a stand or hang from the ceiling.
Of course, with the overlapping fields and reflections from walls, floor and ceiling, the solution wasn’t perfect, but the Beovox 2500 Cube received universal acclaim from audiophile circles at the time for its ability to provide omnipresent sound. Its compact proportions and design, as well as the idea behind it have all contributed Beovox 2500 Cube’s current status as a cult product.
With its six high-frequency tweeters radiating in all directions, Beovox 2500 could be base- or wall-mounted, or even mounted from the ceiling. The compact speakers ensured complete spatial distribution of the highest notes, and its maximum power handling capacity in the range above 2000 Hz was 60W. The speaker was the ideal tweeter for a Beolab system. It could be connected to Beovox 5000 and Beovox 3000.
At the 1967 spring fair in Hanover, B&O and Jacob Jensen – the designer of the speakers – received the IF award for the Beomaster 5000, BeoLab 5000 and Beovox 2500 Cube loudspeakers for outstanding and user-friendly design.
