Beovox MC35

Bang & Olufsen Beovox MC35

Beovox MC35 and MCX35 loudspeakers were two of the smallest (and most economical) speakers that were ever sold by Bang & Olufsen.

They were often sold as part of the cheaper ranges of Beocenters available at the time, and could be used for around-the-house extra speakers as part of Beolink®.

Beovox MS150

Bang & Olufsen Beovox MS150

Beovox Uni-Phase MS150 and M150 were Bang & Olufsen’s answer to the need for loudspeakers that could cope with greater dynamic range and increased demand for serious, no-gimmick sound reproduction.

They were B&O’s biggest and most perfected loudspeakers up to the time of their introduction, designed to reproduce sound with a natural, linear phase quality – even at very high sound pressure levels. Their power handling capacities were specified at 150 watts RMS. However, effective overload protection circuits enabled them to handle brief passages of music way above their ratings

Both speakers reproduced all types of music – from the faintest to the loudest notes – with extreme accuracy and precision, without adding to or subtracting from the signals they received.

In addition, the MS150 was designed to reproduce a clean, powerful bass in a relatively large room. That is why it was fitted with a monitor quality sub-woofer and had a net volume of 64 litres. It reproduced the lowest of tones that any record, tape or FM broadcast could deliver. Apart from the sub-woofer, all other speaker drivers in both models were identical.

Beovox Uni-Phase MS150 were well-balanced loudspeakers that would reproduce all types of music – from the faintest to the loudest tones – with accuracy and precision. They were an excellent match for the BeoLab 8000 music system, and other serious high fidelity systems.

Beovox Uni-Phase MS150 loudspeakers had linear phase and linear amplitude transfer characteristics. This meant that they would reproduce sound accurately, without adding to, or subtracting from the signals they received. Power handling capacity was specified at 150 watts RMS but an effective overload protection circuit enabled them to handle much greater loads.

Behind this successful design lay a new acoustic technology, an integrated loudspeaker design which put Bang & Olufsen in control of all the parameters that affected the loudspeakers’ performance. That is, all, except the room acoustics in which they were situated. The new technology was based upon the use of Fourier analysis, computer-aided design and simulation techniques and laser holography. It helped prove measuring, calculating and testing techniques and thereby led to better cross-over filters’ design, refinement of patented linear phase techniques, control cabinet resonances and the minimisation of diffractions caused by the cabinet’s traditionally sharp-edged profiles. There was also a redesigning of the necessary drivers in order to meet precise construction requirements and perform optimally.

A monitor quality sub-woofer, a 20cm bass unit and a 64 litre net cabinet secured clean, powerful, bass reproduction. The mid-range unit, a 7,5cm dome tweeter, was aperiodically tuned to secure the exact frequency response characteristic required, while the super tweeter ensured excellent high frequency response.

Beovox MS150-2 handled a full 150 watts of power easily and accurately. Even musical peaks exceeding this level offered no danger to the drive units as they were protected by an automatic safety cut-out. All frequencies were reproduced faithfully via the 25cm sub-woofer, 20,5cm bass, 7,5cm mid/phase-link and a 2,5cm tweeter unit. Overall, frequency range was 30 – 20000Hz; the extended bass response being a benefit of the ported reflex cabinet design. Sturdy metal pedestals were included to place the speakers at the correct height and vertical angle.

Beovox P30

Bang & Olufsen Beovox P30

Beovox Uni-Phase P30 loudspeaker handled up to 30 watts RMS power and reproduced sound with neutral, linear phase quality.

They were panel speakers designed to be hung on the wall and are therefore ideal for rooms where space was limited. Only 9cm deep, its volume was 12,9 litres. Fitted with a 16cm woofer and a 2,5cm tweeter. Frequency range 49 – 20000Hz.

The Beovox P30 were effectively a wall mounted S30. They appeared very thin though were in fact slightly deeper than one thought as the resin back protruded a fair bit at the back. Sound quality mirrored that of the S30 with generally good quality sound though they are bass light and must be wall mounted to achieve their best.

Beovox P45

Bang & Olufsen Beovox P45

Beovox Uni-Phase P45 loudspeaker was a revised version of the Beovox P50 and was a high fidelity panel speaker for wall-mounting.

Weighing only 8kg the P45 had a net volume of 25 litres. Frequency range was 40 – 20 000 Hz with less than 1% harmonic distortion. There were two 12,5cm woofers, a special 8cm Phase Link unit and a 2,5cm dome tweeter.

Beovox P50

Bang & Olufsen Beovox P50

“A sound panel in which high-fidelity reproduction and compactness were successfully reunited” – 1974 Catalogue.

Beovox P50 represented a new concept in the design of pressure chamber loudspeakers. They were developed with convenience and homeliness in mind. Their remarkable design provided the sound quality of a “large” speaker without the dominating size and appearance which speakers of this standard had hitherto necessitated. It was possible to place even four top-quality speakers in your living-room without inconvenience.

Beovox P50 could be easily mounted on a wall where their presence would not obtrude upon their surroundings, yet they presented the most excellent sound quality. Frequency response was 40-20 000 Hz with distortion less than 1%. The “P” stood for “panel” and “50” signified power handling capacity – 50 watts RMS (or 80 watts music power). The speaker units were two 12,5cm woofers, a 8cm mid-range dome and a 2,5cm dome tweeter.

Beovox X25

Bang & Olufsen Beovox X25

Beovox X25, X35 and X40 speakers were, at the time of their introduction, newly-developed speakers. The two speakers were very similar in appearance.

Beovox X35 featured a 20cm bass unit and 2.5cm tweeter. Power handling capacity was 30 watts RMS. The cabinets measure 48cm high, 26cm wide and 18 cm deep. They had a built-in wall-mounting facility and were finished in a dark grey metallic effect.
