Centre-Plug
The centre-Plug replaces the traditional dust cap, making the cone both lighter
and more responsive, while also cooling the voice-coil, resulting in a higher
power handling and a stable sound reproduction when playing loud. The de-
sign allows increased power-handling capabilities along with a more uniform,
precise and dynamic reproduction of sound.
The centre-Plug also prevents potential break-up points where the dust cap
would have been glued to the cone. in addition, it prevents over- and under
pressure behind the dust cap when the cone moves back and forth.
The advantage is more dynamic and precise sound reproduction.

HCC (Hard Conical Cone)
The Hcc technology (Hard conical cone) enables the driver to reach far beyond
midrange frequencies before any significant cone break-ups occur. The mate-
rial's rigidity and the membrane's conical shape ensures the unit creates clear
and detailed sound with very little distortion, even at high sound pressures.
This combines with the natural rubber suspension, which effectively prevents
vibrations from travelling back to the diaphragm, the result being a very well-
controlled diaphragm that operates without break-ups up to 4kHz -well beyond
its working range.
