Bang & Olufsen BeoVox Cona

BeoVox Cona

By using smaller loudspeakers in the Bang & Olufsen range – like the BeoVox CX50 or BeoVox C75 passive speakers, all it took to fill out the sound even more was the BeoVox Cona, a passive sub-woofer.

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.

 
 

Review by BeoWorld Member – Evan Bunner

The BeoVox Cona Having waited very patiently for a Cona to come my way, I finally stumbled across not one, but two BeoVox Conas on the internet. I quickly arranged a demonstration the next day. It didn’t take very long to impress me. I loaded the pair into my car with a great sense of satisfaction. However, I had to wait for some din plugs I had ordered off the internet before I could start using them, so my excitement was slightly delayed.

My excitement soon resumed once I received my din connectors. I hastily fashioned them together with some surplus speaker wire of mine and proceeded to connect one of the Conas, as originally directed, to my BeoMaster 4500. Being a passive speaker, it is very handy when you have your Power link ports all filled up with your favorite BeoLab speakers.

Being able to channel both left and right signals to one diver through the Cona’s dual voice coil feature allows the Cona to produce BeoLab level sound at a BeoVox level price. However, I find that combining two signals in a single driver does make the sound much choppier than say if you were to connect two Conas, one signal assigned to each. Additionally, this fight over the driver can create some enclosure rattle, something that can become annoying in heavier listening. I find that a stereo configuration generates much more natural sound.

Since it is a passive speaker, the driver is much smaller than what you would find in an average standalone subwoofer, mostly due to the fact that it has to be able to perform on less power, keeping the Cona from being power hungry. This directly affects the range of the speaker. Being slightly smaller than most standalone subwoofers, the Cona is slightly heightened in the frequency range, making it more of a musical speaker while slightly lacking in movie listening. The heightened frequency range is not very noticeable at higher volumes due to the great amount of bass the Cona can deliver higher up on the volume scale.

In usual Bang & Olufsen style, things are much more aesthetically pleasing and interesting than the bland norm that comes with most other loudspeakers. The BeoVox Cona is no exception.

Visually, the BeoVox Cona generates several comments. First off, one notices the size, very large for a single driver, especially that of 8 inches. This quality quickly earned the title “ottoman” by my girlfriend. So far I have not found a corner the Cona could not squeeze into, so it is a very practical size. They are very subtle but can also retain a good focal point in a modernly appointed room. The roundness of the Cona is a nice departure from the cubic trend of standalone subwoofers we are all used to seeing. I like to maintain the idea that the form of the Cona also serves a function. Coming from the same time period that gave us the Penta and Red Line speakers, I believe that the Cona followed a common trend set by the Penta and Red Line speakers in utilizing a unique cabinet shape to reduce internal acoustic reflections and standing waves by removing parallel surfaces from the construction.

For the first attempt at an individual subwoofer, Bang & Olufsen hit a home run. The sound is very rich and full. The bass is very tight and responsive, even on as little as 55 watts. The bass is light in quantity down low on the volume scale, but can still annoy the neighbors when you crank up the volume. This is definitely a piece for collector interested in past Bang & Olufsen products.

BeoVox C75

Bang & Olufsen BeoVox C75

BeoVox C75

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.

BeoVox 5000 (1967)

Bang & Olufsen BeoVox 5000 (1967)

BeoVox 5000 (1967)

Beovox 5000 was the ideal loudspeaker for the Beolab system.

It had a special bass unit with an extended bass reproduction range, two mid-range units and four high-frequency units. There was provision for individual of mid-range and high-frequency levels and a socket for a high-frequency diffuser (Beovox 2500).

There were three differing incarnations during its life: the first had seven drivers incorporated within its 66 litre cabinet. Available in three different finishes, the B&O logo was gold-plated. Beovox 5700 was the replacement for these high-quality units when their lifespan came to an end.

BeoVox 5000 (1988)

Bang & Olufsen BeoVox 5000 (1988)

BeoVox 5000 (1988)

Bang & Olufsen’s BeoLab and Beovox 5000 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.

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.

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 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 offered.
