DOME
Low resonance frequency, high power handling,
and exceptional headroom for high sound pressure
levels and extreme excursions are all characteristics
of the oversized soft dome tweeter. It is rolled in
carefully around 2.5 - 3.2 kHz, depending on the
model. And the dome is allowed to operate up to
its high frequency limit well beyond 20 kHz without
being rolled off in the crossover.
Incorporating an ultra-thin magnetic fl uid for
cooling, the fl uid has a very high fl ux saturation
point for greater power handling. This also means
superb control of coil movement - even at very high
sound pressure levels.
The dome material itself is very lightweight, and
actually so thin that the coating has to be applied to
hold the material together and uniform.
Under the dome, we have meticulously damped the cavity. The damping material consists of two dedicated parts positioned
directly in the pole opening and on the edge of the centre pole. All this makes the dome tweeter perform in a smooth and stable
manner – adding to the overall quality of reproduction of high frequencies.
