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 main picture above), which 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 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 which 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-coloured LED as opposed to BeoLab 5000’s orange. Both loudspeakers were available with blue or grey fabric.
Quality loudspeakers provide well-modulated sound expression, and at the same time a visual personality that also commands attention. Bang & Olufsen’s BeoLab 3000 and Beovox 3000 loudspeakers had both the voice and the looks for a leading, acoustic role. Because of their thin shape, they became known as Panel loudspeakers.
Panel loudspeakers were one of the most exciting examples of how Bang & Olufsen united advanced technology and stunning design to achieve totally new effects. They didn’t look like high specification loudspeakers,, but their sound gave them away. Even at full volume they kept the total sound picture in perfect balance.
The elegant, flat loudspeakers were designed to be hung on the wall. And with their calm surfaces of blue or grey fabric coupled with beautiful, polished steel they looked like works of art presented in their own right. The idea of the panel speakers was based upon an advanced, acoustic principle that uses the wall as an active part of the sound reproduction, without causing the wall itself to vibrate.
They were available with or without amplifier and display showing which source was playing, at what volume, and which track number on a CD or tape you were listening to.
With display and amplifier the panel, speakers were called BeoLab 3000. Without, they were known as Beovox 3000.
The options depended on which Bang & Olufsen sound system was connected. You obtained maximum utilisation from Beosystems 6500, 4500, 3500 and Beocenters 9500 and 8500.
Why build amplifiers into the loudspeakers instead of keeping them separate?
Because you can reduce the size of the cabinet volume to one-third of the size of a conventional loudspeaker with the same sound capacity.
The principle is called Active Loudspeakers, and what you get is a compact loudspeaker that can play at high volume without distortion or damage to its drive units. Furthermore, when amplifier, treble and bass units are paired for the same task, they can be tailored to compensate for each other’s shortcomings. What you hear is music that sounds exactly like the instrument it originally came from.
Mounting Options
Wall mounting brackets were supplied with this model. No other mounting solution wall 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 Mounting Brackets
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 on to the wall, where they are a genuine and authentic Bang & Olufsen statement.
BeoLab 2500 are active loudspeakers designed to match the BeoSound Ouverture and the BeoSound 3000. With their built-in amplifiers, they sound as if they’re three times their size. Hang them on the wall or place them on bookshelves.
They match both the Beocenter Ouverture and 3000 (previous to this they were used with both the BeoSound 2300 and 2500 music systems) with perspective and clarity, despite their modest dimensions. The explanation of the wide sound lies in the built-in amplifiers in each cabinet: one for bass and one for treble, so that they never have to compete for the same amplifier.
Features:
BeoLab 2500 are active loudspeakers with 2 built-in power amplifier modules to combine with the current (2002) BeoSound 3000 and BeoSound Ouverture. As speakers for the BeoSound 2300 and 2500 music systems, they were available in Blue Lapis, Black Granite, Red Garnet, Green Malachite, Yellow Dolomite and Silver Galena. However, new metal frets were introduced at the end of 2001. From the previous replaceable cloth fronts, they are now manufactured in pearlescent aluminium (see below). These new perforated metal frets presently come in 5 different colours – natural aluminium, black, blue, green and russet to match those of BeoSound 1.
“When it comes to sound reproduction we believe there’s only one relevant parameter: How close can we come to the originally recorded sound. We feel an obligation not to disturb the intentions of the artist by adding unnatural elements to the acoustic image. Therefore all Bang & Olufsen loudspeakers share the same goal. They differ in size and shape and in terms of sound pressure level. But they are all developed to reproduce the natural, unaltered sound as closely as possible ” – Bang & Olufsen catalogue 2001 – 2002
Adaptive Bass Linearisation
Adaptive Bass Linearisation (ABL) is a process patented by B&O and is incorporated in BeoLab loudspeakers. The idea is to use the surplus capacity in amplifiers and driver units, arising by normal listening levels, for a bass extension – a sound reproduction with more bass, than the loudspeaker otherwise would be able to produce.
The function is adaptive. This means that the loudspeaker adapts to the signal it receives. Loudspeaker drivers are therefore fully exploited, without suffering mechanical or electronic abuse, and the built in amplifiers are not subjected to signals would otherwise create an overload situation.
ABL gives stunning bass reproduction considering the size of the loudspeaker in which it is incorporated, under normal listening levels.
Mounting Options
BeoLab2500 were originally mounted to the HiFi with wall bracket 2087 or physically separated and mounted onto furniture as a bookshelf option.
If you wanted to indulge yourself with the finest sound quality then you’d do no better than listening to your favourite pieces of music on Bang & Olufsen’s Beogram CD 6500. Beogram CD 6500 was a replacement for its predecessor, Beogram CD 5500.
It played both 12cm and 8cm compact discs, and housed sophisticated and advanced digital technology. And it offered sound reproduction which would satisfy even the most demanding of listeners.
Beogram CD 6500 could be used as part of the Beosystem 6500 hi-fi system.
The sound reproduction achieved by Bang & Olufsen’s CD 4500 CD player was truly outstanding.
It played both 12cm and 8cm compact discs and had an ingenious ‘step’ function which allowed you to go straight to a chosen track selected from anywhere on the disc. The CD player was one of the most technologically-advanced pieces of hi-fi on the market at the time and yet was one of the easiest to operate. The explicit display always indicated what the CD player was doing all the time – for example, which track was being played, and how many tracks there were on the played compact disc.
Beogram CD 4500 could be used as part of the Beosystem 4500 hi-fi system.
In building the Beogram 4500 turntable, Bang & Olufsen applied all its classic principles to ensure reproduction as close to perfection as possible.
The electronically-controlled tangential arm played each record exactly as it was recorded. And there were built-in systems that helped prevent vibrations reaching the cartridge or turntable. Beogram 4500 employed a finer, ultra-light MMC2 cartridge that combined distinguished sound reproduction with maximum protection for your records.
Beogram 4500 could be used as part of the Beosystem 4500 hi-fi system, and – having an inbuilt RIAA pre-amplifier can be plugged straight into the AUX port of your modern B&O equipment and enjoyed with the minimum of fuss!
If you built up an LP Collection of good music to conjure up wonderful memories, you obviously would have wanted to enjoy it for many years to come. Which is why Bang & Olufsen put so much effort into Beogram 6500.
It was a superb, precision instrument that ensured perfect sound reproduction of your records. The electronically-controlled tangential arm played the record exactly as it was recorded.
The tone arm was suspended in a special Optimum Pivot Point system that prevented vibrations from reaching the MMC2 cartridge which has a stylus pressure of only 1g for minimal friction. And Bang & Olufsen’s special chassis suspension prevented external vibrations from reaching the platter. And Beogram 6500 automatically registered the size of the record you were playing and adjusted the speed accordingly.
The BeoGram 6500 also contained an inbuilt RIAA pre-amplifier, which essentially means you can just “plug in and play” with any modern B&O system through an AUX or similar socket – making this a very desirable deck! Of course as part of the Beosystem 6500, it was part of the top of the line system comprising in addition, the BeoMaster 6500, BeoCord 6500, BeoGram CD6500 and MCP-6500.
In design, technology and operating philosophy, the Beogram 9500 turntable was a perfect match for the Beocenter 9500 system.
Using a light-weight MMC2 cartridge, its electronic tangential arm played each record at the exact angle it was cut giving the most precise reading of the grooves ensuring that every nuance of a recording was captured.
The arm was suspended by a patented Bang & Olufsen system which helped prevent vibrations from any source reaching the cartridge. And the chassis suspension acted as an effective buffer against external vibrations.
This tangential record player was a classic example of Bang & Olufsen’s attention to detail. It had automatic registration of record size and speed, and seven repeat functions. The turntable was based on Beogram 5005.
There was also the benefit of Bang & Olufsen’s patented chassis suspension and special tone arm design, which prevented vibrations from reaching the cartridge during play thus enhancing your pleasure and protecting your records.
The US TX2 had a 110V transformer but had no switching for other electrical voltages. As a comparison, most European models had an inbuilt transformer to allow for switching between other voltages.
This fully-featured radial record player brought an extra dimension to all kinds of music systems.
It was ideal for those who love partying, with automatic anti-skating to prevent distortion, and Bang & Olufsen’s special chassis suspension which made the record player virtually ‘dance-proof’.
There was also automatic registration of record size and speed. Fine quality sound reproduction was provided by the lightweight tone-arm.
This deck was the last of the B&O radial tracking decks and was closely related to the excellent Beogram 5000. This is an excellent choice as a source for vinyl in a modern system requiring very little in the way of set up yet offering good audio performance.
