[QUOTE="Vanquish, post: 108934, member: 84"] One of the finest car audio drivers in the market today ... courtesy of E. Skaaning himself ...... a work of a genius Audiotechnology is a family owned company founded by Ejvind and Per Skaaning with production facilities situated in Stilling, Denmark. For the uninitiated, Ejvind Skaaning was the founder of both the world famous Danish speaker companies. He founded Scan-Speak in 1969 & founded Dynaudio in 1976 where he stayed till 1987. Both gentlemen are very highly respected figures within the European and Danish audio fraternity. The C-Quenze mid unit C-Quenze drivers are based on the same technology as the Flexunits, but use a solid die cast basket instead of the modular basket used in Flexunits. This precludes customized basket dimensions – only inhouse C-Quenze cones or cones with a similar height can be used. The best part of energy during development was put into refinement of the performance in the midrange area. All the materials used, were specially picked to obtain the trustworthiest midrange reproduction. The drivers are extremely fast and move without any dynamic compression due to the mechanical construction. Where needed, they are still able to make adjustments regarding the T/S parameters as well as the physical parameters – FX. Voice coil winding length, magnetic gap height and magnet sizes. The features such as: SD system, Kapton voice coil former and under hung motor structure are still available in the C-Quenze drivers. Hexacoil voice coil winding technique is used. The high ventilation factor through the centre pole piece, under the rear suspension and the perforation to the voice coil, are naturally kept intact, enabling the moving system to accelerate without any compression. Frequency response curves in the C-Quenze drivers have been improved, compared to the Flexunits.
