All the details below relates to the history of Audio Tecnology is taken of "The Danish loudspeaker 100 year anniversary" book and we are extremely grateful to the authors of the book for such a valuable work.

Audio Technology was established by Ejvind and Per Skaaning in 1990 based on an idea of building small series of speaker motorists for customers that wished to have some degree of influence relating to electrical and mechanical parameters, as well as appearance and design of the loudspeaker.

6" driver with 3" voice coil. First chauffeur developed by Audio Technology was the 6" motorist. Audio Technology names its Flexunits motorists after the emissive cone diameter, due to the fact that they operate with great deals of different front ring diameters and shapes. Front rings can vary several centimeters, in spite of utilizing the very same cone diameter. The physical shape of the motorists was quickly established and because it would not be restricted by physical measurements, like heights, etc it was chosen, the chauffeur chassis need to include 2 rings - a front ring and a middle ring, connected by spacers and bolted together. A really versatile construction, that led directly to the name - Flexunits. 6" Flexunits was ended up with regards to the physical construction, however the shape of the cone was still to be developed. It was done according to the 'Trial and error' concept and went on for month. Great deals of tests, measurements and discarded cones saw the day of light. Fortunately, this brought a great deal of experience and the procedure of discovering the best geometry of the cone got simpler for the drivers to come. Sonus Faber (Italian speaker manufacturer) was currently interested in such a driver, so turnover and sales was guaranteed from start. The chauffeur, used in Sonus Faber EXTREMA, was hereby the first commercially used driver of Audio Technology. It was with the Sonus Faber logo on the special shaped front as well as an individual created cone by the concepts of Franco Serblin. About 2000 Extrema mid-woofers have been produced, and the sales of these motorists, have actually contributed importantly to the continuous structure and advancement of Audio Technology. Next newcomer was a 10" unit, also with 3" voice coil, but here advancement was rather faster. The physical style was simply a question of enlarging the existing parts, but the cone structure advancement showed yet again to be quite time consuming. Then, a 4" system was prepared and the need for a smaller voice coil happened. Like the 3" voice coil winding tool, the 2" tool was made as an adjustable tool to produce coils with many possible winding heights. Voice coil former inserted into the tool can be altered by 5 millimeter periods and winding heights to nearly any given 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 a perfect geometry went quick. Experience does matter ... Hereafter, the 5" Flexunits was made and it rapidly turned out to be a popular size driver. A not too big a chauffeur, that has the ability to produce reasonably big noise in a small cabinet. Many loudspeaker produces around the world have ended up being widely known for producing speakers with great sound, on the basis of this chauffeur. Also the Danish Hi-Fi magazine Highfidelity, introduced a DIY task 'Speak & Abyss' with the 5" Flexunits. Due to the narrow structure of the 5" chauffeur, it was required to alter the building of the basket. Instead of mounting the screws visibly from the front, a row of treats were concealed under the rubber-surround, allowing a somewhat smaller sized assembly. This action was rapidly adopted into the other chauffeurs. 4", 5", 6", 8", 10", 12", and 15" motorists were now offered (1994) - some with 2" voice coil only - others with both 3" and 4" voice coils.

C-Quenze arrives Previously, all motorists were built with the bolted together chassis, however in 2001 a brand-new series occurs - the C-Quenze series. This series of drivers are in every aspect developed from the same parts and material as the Flexunits, with exception of the frame. It is now a cast frame. This implies the versatility is minimized, however some specifications can still be altered. The cones are likewise changed as the energy is taken into getting a somewhat more comprehensive bandwidth. As this chauffeur is a bit more cost-effective than the Flexunits, it becomes quite popular, however still, there are customers that desire what they call 'The real thing'.

In 2009, the Sandwich Cones appears. It is made from two relatively thin carbon enhanced paper skins, which are glued together with broadening foam glue. The structure is light, however very stiff.

LR - magnet system Last effort is motorists with an aerodynamic magnet system - the LR system (2012 ). The pole plates are rounded to an aerodynamic shape, preventing aero sounds and distortion from the chauffeur. The LR system comes only with the 120 mm magnet so far. Today, Audio Technology ApS is still owned by Per Skaaning and two of his bros.

Timeline. 1990 - Audio Technology ApS was established.

1991 - First commercial speaker system using Audio Technology drivers is checked in German Magazine Audio under the headline: "Nur fliegen ist schöner" significance: "Only flying is Nicer".

1993 - Guarneri Homage of Sonus Faber is introduced. The chauffeur for this speaker is the biggest number of Flexunits produced. Copy No 001, is placed in the Violin Museum in Vicenza.

1994 - The biggest Flexunits - 15" - is finished. The very first Flexunits with 4" voice coil, implying great power handling. Four pairs were offered to Ace of Base studios in Sweden.

1995 - The Parcifal of Verity Audio in Canada is introduced. A really popular speaker that has been produced in basically the same design for 20 years.

1999 - The KA system sees the dawn of light. Full bodied bass at low levels, combined with great damping at X-max is possible.

2002 - For the first time, Audio Technology chauffeurs have the honor of being in "Speaker of the Year" in Stereophile Magazine represented by Rockport Technologies Antares.

2007 - Six speakers with Audio Technology motorists in "Recommended Components" of Stereophile Magazine. Speakers from Peak-Consult, Sonus Faber and Verity Audio are represented.

2008 - The sandwich cone motorists are presented, offering the Audio Technology woofers an upgrade relating to low distortion and 'edge' in the general sound experience.

2010 - The Innovative in The Absolute Sound: "... then I think that you will find that Verity's Lohengrin isn't trigger for purchaser's remorse but prolonged elation.", J. Heilbrunn TAS.
