Beovox S4500 Passive Loudspeakers

BeoVox Loudspeaker

Production: 1981 - 04/1983

Designer: Jacob Jensen

Beovox S4500 (type 6318) Uni-Phase loudspeakers could handle 45 watts RMS (75W music power) and were based upon the earlier Beovox S45.2 loudspeakers.

They were not very popular and were subsequently withdrawn after but a short period of time.

They may not have looked like high-specification loudspeakers - more like works of art - but their sound immediately gave them away. Even at full volume, they kept the total sound picture in perfect balance.

Bang & Olufsen's BeoLab and Beovox 5000 / 3000 speakers had both the voice and the looks for a leading, acoustic role. And because of their looks, they were known as Bang & Olufsen's range of panel loudspeakers. Panel loudspeakers were one of the most exciting and interesting examples of how Bang & Olufsen united advanced technology and stunning design to achieve totally new effects.

Design as a work of art

The elegant, flat-panel loudspeakers were created to hang on the wall. And with their calm surfaces of blue or grey fabric coupled with polished steel, they could be taken for works of art. But the design was only partly for visual effect. The form of the panel speakers was founded on an advanced, acoustic principle that uses the wall as an active part of the sound reproduction process - without causing the wall itself to vibrate.

Optional display and amplifier

The panel loudspeakers were available in two sizes - each with or without an amplifier and a display showing which source was playing and at what volume. Also, it told you which track number on a CD or tape you were listening to. With display and amplifier, the loudspeakers were called BeoLab. Without, they were called Beovox. The option depended upon which Bang & Olufsen sound system was connected. BeoLab speakers were designed to match Beosystem 6500, 4500, 3500, and Beocenter 9500 and 8500.

Mounting Options

Wall mounting brackets were supplied with this model. No other mounting solution wall was offered.

Bang & Olufsen's preferred supplier for brackets and stands, STBbrackets, have made a range of solutions specifically for this model. Distributed throughout the World by the Bang & Olufsen store network, the STB options add to the diversity of mounting options and positions available.

Wall Bracket for BeoVox & BeoLab flat panel speaker range

WB3000 has been introduced to meet a growing demand to mount Bang & Olufsen flat panel speakers to the wall. The bracket (sold as a pair) is a faithful reproduction of the original which was supplied with the speakers. These beautiful speakers can now be installed onto the wall, where they are a genuine and authentic Bang & Olufsen statement.

Beolab 4500 Active Loudspeakers

BeoLab Loudspeaker

Production: 1992 - 1996

Designer: Gideon Lindinger-Lowy

BeoLab 4500 was a wall speaker which was no more than 8cm deep. It had a built-in (active) amplifier and extended bass reproduction, which used the wall as a reflector. The display told you which source that BeoLab 4500 was reproducing at any one time.

There were two versions of this panel loudspeaker. The pure Beovox 4500 loudspeaker (shown here) and BeoLab 4500 with built-in amplifier and Dynamic Bass Equaliser (shown in the main picture above), automatically compensated for the inability of the human ear to perceive deep bass tones at low volume

The design of BeoLab 4500 and Beovox 4500 was based on an acoustic principle that allowed the loudspeaker to use the wall to enhance the bass level. The cabinet let the sound waves reflect off the wall and out into the room without delay. This made it possible to reduce the depth of the cabinet to just 8cm, so the loudspeaker becomes a natural part of the wall décor.

BeoLab 4500 had a display that indicated sound source, volume, and which track on CD or tape that you were listening to. In looks, it was similar to the BeoLab 5000 active speaker but smaller. The display too was in a green-colored LED as opposed to BeoLab 5000's orange. Both loudspeakers were available with blue or grey fabric.

Beovision MX4500

BeoVision

Production: 1988 - 05/1990

Designer: David Lewis

A slightly larger version of the Beovision MX3000 this 28″ television suffered from similar faults - especially with its CRT - like its smaller sibling. It was withdrawn from sale after but a year or so.

The television suffered from poor reliability and was never the success that Bang & Olufsen hoped that it would be.

The television was soon after replaced by the Beovision MX5000

Beovision LX4500

BeoVision

Production: 1990 - 03/1992

Designer: David Lewis

Replacing Beovision LX2502, the Beovision LX4500 was a luxurious 25″ multistandard color television with the benefit of stereo reception.

Fitted with a contrast screen, Teletext, and the possibility of using a motorized stand, the television had a very wide range of color options available for it. It used the Beolink 1000 remote control terminal and offered hi-fi quality sound.

For a novelty value, it was able to keep tabs on other TV programs and sources by way of a Picture-in-Picture module when it could show a small TV image in one corner of its screen. Likewise, it could also offer to the viewer a choice of either four, nine, or sixteen miniature TV clips displaying just what the other stations had to offer.

Datalink connections were built in to link the set with another suitable Bang & Olufsen audio or video product, and Power Link sockets were provided for which to add a pair of Beolab active speakers like Beolab Penta III.

The Beovision LX 4500 was eventually surpassed by the arrival of Beovision LX 5000.

Designer: David Lewis

A rebadged Beovision L4500, the Beovision LS4500 was a 25″ multi-standard color television complete with NICAM sand A2 stereo modules. It was also fitted with Datalink and Power Link connectors for use with Beolab active loudspeakers.

A very good selection of finishes was available for this TV and a contrast screen finished with a metalized coating ensured excellent viewing.

A full-range speaker system was included and the sound obtained was rich and warm. The set was prepared for use with the Best LM satellite decoder.

A Beocord V3000 was the recommended VHS video recorder to be used for the recording and playback of TV programmes.

The television was subsequently replaced by the Beovision LS5000.

BeoSystem 4500 was comprised of BeoMaster 4500 receiver, BeoGram 4500, BeoGram CD 4500, BeoCord 4500 cassette recorder, Beolab 4500 active speakers.

Co-operatively designed by both Jacob Jensen and David Lewis, Beosystem 4500 received the Japanese Good Design Award in 1989 for its elegant and functional design.

Production: 1988 - 05/1994

Designer: Jacob Jensen David Lewis

Documents: Owners Manual, Owners Manual, Service Manual

The desirable Beosystem 4500 - with Beomaster 4500 at its heart - was the final inception of a long line of Beomaster 1900-family members which had been first drawn up by the pen of Jacob Jensen way back in the mid-1970s. Always very popular because of its sleek, modern looks, Beomaster 4500 used the latest technologies, linking it with its Beogram 4500 record deck, Beocord 4500 cassette deck, and Beogram CD4500through Datalink to form the Beosystem 4500. Both an internal 40W per channel amplifier was incorporated as well as the necessary Power Link connectors to drive the latest BeoLab amplified speakers.

Based upon a close cousin - the Beocenter 9500 - Beomaster 4500 incorporated all the necessary elements of that design (sans CD player and cassette deck) brought together into a neater package.

The whole of the Beosystem 4500 could be mounted on a wall where it looked exquisite and sophisticated with its darkened touch-sensor panels and brightly polished aluminum casing.

This receiver was the last of a long line. As new sound sources took over from the (very) tried and trusted LP record, there was no need for manufacturers to incorporate a record deck. Music systems could, therefore, become more integrated and smaller. Beomaster 4500 was not replaced as such, as the new Beocenter 2300/ 2500 took over offering a different feel and outlook.

Beocord 4500 cassette recorder was a stereo cassette player that was designed to complement the overall look and technical characteristics of the Beosystem 4500. In its livery of black, white, and a mass of polished steel it looked very modern and still does. Time has made no impact on its looks at all.

As well as Dolby B NR, the player featured HX-Pro and auto-reverse. It also became ’state of the art’ with its motorized polished lid which rose to attention at the touch of the sense-touch display.

The model replaced Beocord 3300.

A beautiful-looking slim-lined CD player which matched perfectly the rest of the Beosystem 4500. The unit was equally at home on a shelf as hung up on the wall where the whole ensemble looked like a piece of modern art.

It was the finish of the CD cover which differentiated itself and its predecessor, the Beogram CD3500, in that the 4500 was highly polished against the dull grey livery that the Beogram CD3500 possessed. Technically they were identical.

The Beogram CD4500 was produced for use with Beosystem’s components when it could be controlled remotely. Without Beomaster 4500 the CD player was very basic indeed.

BeoGram 4500

BeoGram Record Decks

Production: 1988 - 05/1991

Designer: Jacob Jensen

Documents: Service Manual, Schematic, Owners Manual

In comparing this record deck with the Beogram 9500, the only difference - as the overall exterior finish of the two machines were identical - was that Beogram 4500 had an RIAA pre-amplifier built-in, whereas the Beogram 9500 did not.

The Beosystem 4500 (of which Beogram is a part) has always looked like a beautiful system, especially as the components could be hung on the wall and displayed next to each other. For obvious reasons, Beogram 4500 could not be attached in precisely this same fashion although a special metal shelf could be bought to use the turntable within the group.
