[biblehomechurch.org](http://www.biblehomechurch.org/message.html)<br>All the info below regards the history of Audio Tecnology is taken of "The Danish loudspeaker 100 year anniversary" book and we are really grateful to the authors of the book for such an important work.<br>
<br>Audio Technology was founded by Ejvind and Per Skaaning in 1990 based on a concept of building small series of speaker drivers for clients that wished to have some degree of impact relating to electrical and mechanical criteria, along with appearance and design of the speaker.<br>
<br>Iconic products<br>
<br>6" driver with 3" voice coil.
First motorist developed by Audio Technology was the 6" motorist. Audio Technology names its Flexunits chauffeurs after the emissive cone diameter, because they run with great deals of different front ring sizes and shapes. Front rings can vary numerous centimeters, despite utilizing the same cone diameter. The physical shape of the chauffeurs was quickly developed and because it would not be limited by physical dimensions, like heights, etc it was decided, the motorist chassis need to include 2 rings - a front ring and a middle ring, linked by spacers and bolted together. A very versatile building and construction, that led straight to the name - Flexunits. 6" Flexunits was ended up with regards to the physical building and construction, but the shape of the cone was still to be developed. It was done according to the 'Trial and mistake' principle and went on for month. Lots of tests, measurements and disposed of cones saw the day of light. Fortunately, this brought a lot of experience and the process of finding the right geometry of the cone got much easier for the chauffeurs to come.
Sonus Faber (Italian speaker maker) was currently interested in such a chauffeur, so turnover and sales was guaranteed from start.
The driver, used in Sonus Faber EXTREMA, was hereby the very first commercially used motorist of Audio Technology. It was produced with the Sonus Faber logo on the unique shaped front as well as a private developed cone by the concepts of Franco Serblin. About 2000 Extrema mid-woofers have been produced, and the sales of these drivers, have actually contributed notably to the ongoing structure and advancement of Audio Technology. Next newbie was a 10" unit, also with 3" voice coil, but here advancement was somewhat much faster. The physical style was simply a question of the size of the existing parts, but the cone structure development proved yet again to be quite time consuming. Then, a 4" system was planned and the need for a smaller sized voice coil happened. Like the 3" voice coil winding tool, the 2" tool was made as an adjustable tool to produce coils with lots of possible winding heights. Voice coil previous placed into the tool can be altered by 5 millimeter periods and winding heights to practically any provided objective. Also, the impedance can be of your own option.
The 4" Flexunits was constructed on the basis of the exact same ideas and from then cone structure set to an ideal geometry went fast. Experience does matter ...
Hereafter, the 5" Flexunits was made and it quickly ended up being a popular size chauffeur. A not too huge a chauffeur, that has the ability to produce fairly big noise in a little cabinet. Many loudspeaker makes around the globe have actually become widely known for producing speakers with excellent noise, on the basis of this driver. Also the Danish Hi-Fi magazine Highfidelity, introduced a do it yourself project 'Speak & Abyss' with the 5" Flexunits. Due to the narrow structure of the 5" motorist, it was needed to change the construction of the basket. Instead of installing the screws visibly from the front, a row of deals with were hidden under the rubber-surround, allowing a somewhat smaller sized assembly. This action was quickly adopted into the other motorists. 4", 5", 6", 8", 10", 12", and 15" chauffeurs were now available (1994) - some with 2" voice coil only - others with both 3" and 4" voice coils.<br>
<br>C-Quenze gets here
Previously, all motorists were built with the bolted together chassis, however in 2001 a new series comes around - the C-Quenze series. This series of drivers are in every element built from the same parts and product as the Flexunits, with exception of the frame. It is now a cast frame. This indicates the flexibility is minimized, but some criteria can still be changed. The cones are likewise altered as the energy is taken into getting a slightly more comprehensive bandwidth. As this chauffeur is a bit more economical than the Flexunits, it ends up being quite popular, however still, there are clients that desire what they call 'The genuine thing'.<br>
<br>In 2009, the Sandwich Cones becomes offered. It is made from 2 fairly thin carbon reinforced paper skins, which are glued together with expanding foam glue. The structure is light, however very stiff.<br>
<br>LR - magnet system
Last initiative is chauffeurs with an aerodynamic magnet system - the LR system (2012 ).
The pole plates are rounded to an aerodynamic shape, avoiding aero noises and distortion from the driver. The LR system comes just with the 120 mm magnet up until now.
Today, [Audio](https://www.zycoo.com/voip-gateways/) Technology ApS is still owned by Per Skaaning and 2 of his bros.<br>
<br>Timeline.
1990 - Audio Technology ApS was founded.<br>
<br>1991 - First commercial speaker system utilizing [Audio](https://www.zycoo.com/solutions/) Technology drivers is checked in German Magazine Audio under the heading: "Nur fliegen ist schöner" meaning: "Only flying is Nicer".<br>
<br>1993 - Guarneri Homage of Sonus Faber is presented. The driver for this speaker is the most significant number of Flexunits produced. Copy No 001, is placed in the Violin Museum in Vicenza.<br>
<br>1994 - The greatest Flexunits - 15" - is completed. The first Flexunits with 4" voice coil, implying terrific power handling. Four sets were offered to Ace of Base studios in Sweden.<br>
<br>1995 - The Parcifal of Verity Audio in Canada is introduced. A popular speaker that has been produced in more or less the same design for 20 years.<br>
<br>1999 - The KA system sees the dawn of light. Full bodied bass at low levels, integrated with excellent damping at X-max is possible.<br>
<br>2002 - For the very first time, Audio Technology chauffeurs have the honor of being in "Speaker of the Year" in Stereophile Magazine represented by Rockport Technologies Antares.<br>[jkpeterson.net](http://jkpeterson.net/fa/)
<br>2007 - Six speakers with Audio Technology chauffeurs in "Recommended Components" of Stereophile Magazine. Speakers from Peak-Consult, Sonus Faber and Verity Audio are represented.<br>
