“BeoLab 4 is a compact, flexible loudspeaker concept at a highly attractive price point. In addition to its use with the BeoSound 4 music system, BeoLab 4 can also be combined with PCs or be part of other Bang & Olufsen music systems. Offering a large number of positioning options, BeoLab 4 is scheduled for initial roll-out in the second quarter “- taken from Bang & Olufsen’s Financial Report, August 2005 .
BeoLab 4 was launched in November 2005 as a new entry-level loudspeaker concept. They are designed to be discreet yet offer exceptional performance for their size. They can be used as stereo loudspeakers with an audio system, as front or rear loudspeakers within a surround sound set-up, and as link room loudspeakers or with a computer.
BeoLab 4 are 2-way stereo loudspeakers with a 2cm tweeter and a 10 cm bass loudspeaker. Each driver is powered by a 30 Watt ICE power amplifier. They also feature a placement switch to adapt the bass performance depending on their position in the room. This is similar in operation to BeoLab 2 with a wall-mounted, corner or free-standing position. In line with the versatile concept, BeoLab 4 adapts its bass performance to the specific placement in the room. A switch is set to match a wall-mounted position, a corner position or a free-standing position to ensure optimum performance. BeoLab 4 features Adaptive Bass Linearization (ABL), Bang & Olufsen’s proprietary technology for ensuring superior bass performance from loudspeaker cabinets with modest physical dimensions.
Pyramid power to super charge your laptop
With a 3.5 mm mini jack Line input, dedicated PC mode and low price, BeoLab 4 is a realistic solution to be sold with non B&O masters such as PCs or as even for portable MP3 players There are two new adaptors to support connection to these sources:
6270273 2 – piece set of 3.5 mm mono mini plug > RCA M, for BL4 w/ non B&O system.
6270250 3.5mm stereo mini plug > 2 x 3.5 mono mini plugs for PC connected to BL4s
Placement
To support the versatility of the loudspeaker, BeoLab 4 is supported with a range of stand options. On its built-in foot, BeoLab 4 can easily be placed on a bookshelf or a table. Furthermore, BeoLab 4 can be mounted on the wall or to the ceiling by means of the optional wall and ceiling brackets. Finally BeoLab 4 can be placed on a dedicated floor stand.
Colour options
The covers are made of a special fabric and will be available in 4 different colours – Black, Dark Grey, Red and Blue. Thanks to a simple snap-on system, it is easy for the customer to change to another colour if required.
With the release of the BeoLab 4 loudspeaker, Bang & Olufsen has once again shown that excellent sound is wonderfully compatible with the design and crafting of a compact and intriguing cabinet. BeoLab 4 will be available towards the end of 2005. Despite its modest size, the pyramid-shaped BeoLab 4 is a true hi-fi loudspeaker, with the amplifier built in to the loudspeaker unit and a range of Bang & Olufsen proprietary acoustic technologies ensuring the best performance. In terms of design and placement options, BeoLab 4 is the perfect accompaniment to the new BeoSound 4 audio system, and the small dimensions suit well as rear speakers for home cinema, or as superbly performing PC loudspeakers.
Flexibility is the key
“In today’s audio market, flexibility is central to our business. Our customers expect to be able to hear music wherever they may be, without any diminishment in quality,” says Michael Jensen, Product Manager, Bang & Olufsen. “BeoLab 4 complements our other BeoLab loudspeakers and sound solutions by ensuring that listening experiences from the living room to the bedroom or home office are of an equally high quality.”
It is often unnecessary to use large loudspeakers as the rear speakers for home cinema, and BeoLab 4 can fill this role. Furthermore, BeoLab 4 has a dedicated PC mode, making it a superbly performing PC loudspeaker. Bang & Olufsen’s well-known BeoLink system ensures the total integration of all entertainment at home, and BeoLab 4 is a great solution for remote loudspeakers that can be placed discretely around the house and linked to home entertainment systems.
A perfect blend of expression and technology
BeoLab 4 is available with a range of stand options for the wall, floor or table that complement the stands for the new BeoSound 4 audio system. BeoLab 4 can even be tastefully hung from the ceiling, and the cloth covers are available in four colours. Three bass presets ensure that BeoLab 4 performs according to its placement in a room – whether in a corner, against a wall, or free-standing in the room.
BeoLab 4 is, like all BeoLab loudspeakers, an active loudspeaker, meaning that the amplifier unit is placed in the cabinet to ensure no deterioration of signal strength between the amplifier and loudspeaker unit. The ICEpower amplifier unit used is a patented Bang & Olufsen solution, allowing for an ultra-compact design, high power output, and cool operation. Adaptive Bass Linearisation, another proprietary Bang & Olufsen technology, offers superior bass performance from modestly- dimensioned loudspeaker cabinets. In addition, circuit protection technology ensures BeoLab 4 never overheats.
Mounting Options
BeoLab4 were conceived as a table top speaker with optional floor stands featuring a stainless steel turned pole. Cables could not be internally routed within the stand and so a silver sock was supplied, which proved not to be popular.
After much anticipation, Bang & Olufsen have released the BeoLab 9. This acoustic lens speaker had been expected for some time, and it effectively replaces BeoLab 1 which was discontinued.
The design of BeoLab 9 continues B&O’s move away from elegant though easily imitated column loudspeakers to shorter, rounder forms with larger cabinet volumes and better potential for strong bass performance. B&O’s distinctive acoustic lens is also present, and the speakers’s height means that it is perfectly positioned at ear-level when the listener is seated.
The acoustic lens is cast from zinc and plated with matt chrome. Its prominent position gives the speaker a slightly hunched appearance – but B&O compare it to a lighthouse. The overall proportions are pleasing and there are some very nice details. For example, the power LED is concealed inside the acoustic lens, and the cooling fins/vents at the rear match the curve of the cabinet. The majority of the cabinet is fabric covered – black will probably be the most popular choice here, but it is also available in dark grey, blue and red.
There are three drivers: a 10” bass unit in an 18 litre enclosure, a 5” mid-range unit in a 4 litre enclosure and a 0.75” treble unit in the acoustic lens. All drivers are separately amplified, but there is only one ICEpower amplifier of 500W which drives the bass unit. The mid-range and treble units each have their own 100W analogue hybrid amplifier.
Packed with advanced technology, BeoLab 7 is, quite simply, the most powerful stereo speaker ever developed for TV. With six individual driver units, all powered by their own digital ICEpower amplifier, BeoLab 7 delivers an unequalled sound performance for your TV viewing. The beam-shaped loudspeaker below the screen provides superb acoustic performance and signifies the presence of sound as an integral part of your viewing experience. Musically, the speaker rivals many hi-fi systems, and is quite capable of being used as a BeoLink speaker.
The natural fit
BeoLab 7 is specially developed for BeoVision 7 to contribute the ultimate stereo sound performance to the viewing experience. BeoLab 7-1 is the natural accompaniment for the BeoVision 7-32 LCD television, while the broader beam of BeoLab 7-2 is designed for BeoVision 7-40. In addition, BeoLab 7 stereo loudspeakers fit naturally under the BeoVision 4 plasma screen, or under a projection screen. In this application, the speaker can be either wall-mounted or placed on a special tabletop stand.
Colours to match
Long and lean, BeoLab 7-1 and BeoLab 7-2 look at home under a BeoVision 7 or BeoVision 4, or as part of a projection screen setup. The shorter BeoLab 7-1 is best suited for the BeoVision 7-32” screen. The loudspeaker cabinet is made from a single piece of aluminium and coated in a resilient black soft-touch lacquer. The perforated aluminium front grill now comes anodised in five different colours: Light and dark grey, blue, red and black.
A firm grip on powerful sound
A special three-way bass reflex construction incorporates six individual units – two each for treble, mid-range and bass. Each driver is powered by a unique built-in ICEpower amplifier, delivering a combined effect of 750 watt. In addition, BeoLab 7-1 and 7-2 are equipped with thermal protection circuits and Adaptive Bass Linearisation (ABL), which ensures maximum performance without distortion, even at very high volume. Bang & Olufsen has a quarter of a century of experience making loudspeaker cabinets from extruded aluminium. This technique allows for very rigid and compact enclosures with powerful sound performance.
Note that BeoLab 7-1 was designed to be used with the BV4-37 and BV4-42. The wider BeoLab 7-2 may be used with the larger-version BeoVision 4: BV4-50 and BV4-65.
Mounting Options
All four versions of BeoLab 7 were designed for incorporation with Bang & Olufsen’s motor stand options.
Providing the ultimate true-to-life sound experience, BeoLab 1 will open your eyes and ears to what a loudspeaker should look and sound like.
“BeoLab 1 is for everyone who has a heart for superior sound. You can turn your stereo up as loud as you want and still experience music the way it was meant to be. ” The quality of a loudspeaker has never only been about its ability to play loudly. What’s just as important is being able to hear the finest nuances in your favourite piece of music – regardless of whether you’re listening at the highest or lowest volume level. As our most powerful loudspeaker, BeoLab 1 will fill the largest room in your house with a sound that’s as close to the original as you can possibly get ” – B&O catalogue 2001 – 2002.
“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.
Eye-opening sound
If the sounds you listen to, reflect the mood you’re in, then BeoLab 1 is an invitation to express yourself to the full. Behind the elegant design lies a powerhouse of sound technology that can enhance the best of movies or take your favourite piece of music to new heights. BeoLab 1 will, quite simply, open your eyes and ears to what a loudspeaker should look and sound like.
Unique cabinet
Three years of the toughest research and development have produced a loudspeaker at the cutting edge of acoustic technology. The BeoLab 1 cabinet is divided into three individually sealed units, utilising vibration-damping materials normally only seen in the car industry. The built-in amplifiers powering each unit are calibrated and customised to ensure a uniform performance in the soundscape that’s created
Top line loudspeaker
BeoLab 1 delivers the purest, clearest sound ever heard from a Bang & Olufsen loudspeaker. With aural reproduction as close as you can get to the original, it allows you to distinguish each instrument playing in an orchestra and every word of a song. A single continuous piece of aluminium forms the rigid backbone of BeoLab 1. Strong enough to withstand the powerful vibrations, its curved design also eliminates any sharp edges or joins that could compromise sound quality.
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.
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.
ICEPower®
BeoLab 1 also makes use of Bang & Olufsen’s innovative ICEPower® technology. With practically no electric power loss and a greatly reduced cooling space, the new, compact digital power amplifier allows the bass unit in BeoLab 1 to produce a sound far beyond the dimensions of the cabinet.
The speaker with many names
“When the concept for BeoLab 1 was decided on almost two years ago, there was a lot to live up to. The loudspeaker project changed names several times during the process. First it was called Loudspeaker 8, then 12, 14, X and finally 15. Later on the commercial name BeoLab 1 was chosen.
From the start it stood tall at two metres. Then it was reduced by a few centimetres to the present 1.84m. Nonetheless, BeoLab 1 is actually only half as large as the Penta in terms of physical volume and only three times larger than the BeoLab 8000. The basis for the development work was to create a loudspeaker which delivers perfect sound in terms of tonal balance and authentic reproduction, with compactness of expression but also high sound pressure, which is easy to integrate with the design and furnishing of the home and which can be placed anywhere. It was truly a great challenge to achieve all this in one and the same loudspeaker.
There was no doubt that sheer amplifier power was needed to replace high volume. However, this also entailed a risk that a loudspeaker might burn up. So the department designed a completely new protective circuit which automatically turns down the amplifiers in extreme conditions, to reduce the heat in the loudspeaker units. So there is no risk of it burning off. BeoLab 1 also features ICEPower®, which is a revolutionary new Bang & Olufsen technology entailing high energy savings due to the low heat development.
Robust, sound craftsmanship
Another difficult problem to solve was that it had to be possible to adjust the loudspeaker to any room, to achieve the optimum listening experience. This is a question of avoiding too much bass when the loudspeaker stands in a corner and too little bass when the loudspeaker stands freely. The solution is the option to adjust the loudspeakers manually to give the same tonal range, no matter where they are placed.
Throughout the production process the loudspeaker is developed to ensure simplicity at every production stage. So this is an extremely robust, soundly crafted, product.
Hermetically sealed
During the process the department received a nasty shock, however, when they carried out the first tests in a hot, humid environment. The loudspeaker just would not function when it was released from the artificial tropical paradise at the Struer site. A new trial was run and the same thing happened. Now the department’s engineers were sweating as much as the loudspeaker had done in the heat cabinet, until it was discovered that the temperature had been turned up an excessive 15 degrees Celsius and the humidity by 3% more than the already very stringent test requirements. So when the loudspeaker was opened, the water practically flowed out of it.
It must have entered as steam, the same designer states today and cites an example of how a BeoLab 1 was shipped as air freight to Singapore. On its arrival, faults were found in the mid-range loudspeaker where the membrane had subsided inwards. The simple explanation was that the cabinet behind the mid-range unit was so impermeable that it could not equalise the changing air pressure during the flight. So the solution was to make a small hole in the mid-range cabinet, to avoid this problem.
Difficult cabinet process It is not the intention to adjust the cabinet to excess. It is the largest aluminium profile B&O has made so far and in fact one of the largest in Europe within high-gloss alloys. In practice, the profile consists of a very fine surface which due to its size is very difficult to manufacture without flaws. However, using specially manufactured equipment technicians have managed to achieve a polish which is both beautiful and perfect.
The process is difficult, however, primarily because the profile is both flat and round. This in itself makes the polishing work difficult.
Sheer force and true to nature
Despite its complexity the BeoLab 1 has a shorter production time than the Penta. One reason is that the entire amplifier section is received ready-assembled from a sub-supplier in Scotland, but according to B&O’s design and instructions. Furthermore, the technology is generally very compact. Engineers have devoted a lot of time and resources to this work. However, the investment is expected to be recouped via faster, more effective production.
If you ask three of the men behind it – Villy Hansen, Poul Praestgaard and Henrik Sjostrand – to say what is most wonderful about the BeoLab 1, they all agree that its supreme quality is that when the user listens to music, he or she will forget to listen for the bass, mid-range tone and descant, but simply enjoy the music. Nobody remembers that the sound is emitting from the loudspeakers. Another aspect is the interplay between form and function. It lives up to what its appearance promises, even the great expectations of the sound experience created by its height. in addition to this comes its sheer force, the high precision of the bass and the authentic reproduction, as well as the simple and robust structure, which is also to the satisfaction of the customer setting up the loudspeakers.
“It really is the best ever. It cannot be followed, and we have to say that an era is now over. We have quite simply completed the portfolio as it stands today. Now we have to use other methods to surprise. Idealand has been working on this and we will be back” the acoustics team state.
Now they are all waiting in great anticipation to see whether the demand for Penta continues, even though it is no longer produced. As was the case with the BeoLab 5000, of which an American recently ordered 30 sets. When told that production had long since lapsed, he asked quite seriously what it would cost to start it up again.

Superior sound quality
What does sound look like? What colour does it have? At Bang & Olufsen, we believe it should be as clear and precise as possible, but that doesn’t mean it has to be invisible. With BeoLab 1 sound makes a statement. It takes our pursuit for natural sound reproduction to a new level and delivers the ultimate true-to-life audio experience. We believe it’s the purest sound ever heard from a Bang & Olufsen loudspeaker. Since no two loudspeaker units have exactly the same physical characteristics, we calibrate them individually to make certain that the sound of each and every BeoLab loudspeaker leaving the factory is identical
Performance
To ensure an optimal performance every time you listen to it, a BeoLab loudspeaker constantly “fine-tunes” the signal received from the sound source before distributing it out to the separate bass and treble power amplifiers
Appearance
Using aluminium for the cabinets is not just about looking good. Despite a thickness of only a few millimetres, it’s a remarkably strong metal that’s easily shaped to eliminate the problems normally experienced with loudspeakers made by traditional materials
Colours
Once the surface has been polished until it shines like a mirror, it’s dyed and given a tough ceramic coating that seals and protects the coloured exterior. The 5 strong colours match with the existing Bang & Olufsen range, and have been carefully chosen to compliment any environment in which they’re placed. Choose between silver, blue, black, red or green (1999 – 2003 range).
