Composite material, made of Carbon fibres, Glass fibres, and proprietary damping linking both materials.
CGF allows to adjust the cone stiffness and damping according to the application requirements.

Paper cone with hexagonal structure embossed on its back.
It allows to keep very light cone and increase the stiffness to move the cone break-up on higher frequency, 1 octave above the useful bandwidth.

Reach a constant force factor is a key feature to ensure excellent loudspeaker performances, with high dynamic capability and low THD.
Kartesian products use some innovative solution to keep constant Bl(X) over large excursion

Inductance is usually the source of many limitation in loudspeakers performances.
Kartesian has developed many solution, solving most of the inductance issues, which can be adapted in every loudspeaker design.

foKus field

Intense magnetic filed is required to built efficient driver. The shape of the pole pieces is more important than magnet size or grade.
Kartesian has engineered advanced pole pieces geometry to focus more intense and symmetric magnetic field on the voice coil.

Radial magnets

kartesian radial magnets technology is unique because it uses thick magnet which is only possible with innovative radial magnet charger. Furthermore, Cooper spacers are located between magnet to reduce inductance modulation.
The magnetic Yoke is also specifically shaped to ensure constant field over the full magnet height (up to 50mm)

The resonance frequency depends on the spider stiffness.
If it help to clumsily protect the driver in largest excursion, the stiffness increasing makes the Fs[Hz] increasing too, which disturb all T&S and the low frequency response.
Kartesian has engineered spiders to perfectly control the stiffness on the full excursion of the driver.

The surround must ally various and opposed features as excursion capability, low mechanical damping, high frequency break-up, ...
Kartesian uses specific NBR material with advanced geometry to ensure faultless performances of the loudspeakers.

On high frequency drivers, the back wave is controlled by the back chamber.
The design of this back chamber set a significant part of the performances, especially in time domain.
Kartesian drivers use coupled rear chamber to ensure efficient damping and sound wave management.

The subwoofers with large excursion capabilities move significant air volume, under high speed velocity.
Kartesian has designed many devices to prevent noises during subwoofer working.

The voice coil temperature usually increase with high power input signal and/or long listening period, which create efficiency lost and dynamic compression.
Kartesian consider the dynamic capability as key feature of a driver, and we engineered few solution to manage voice coil temperature in any circumstances.
