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 - 3.1 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
fluid for cooling, the fluid has a very
high flux 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
contributes with a significant part of the
dome structural stiffness.
RIBBON
The ribbon tweeter features a broad
frequency band and superb dispersion
in the higher frequencies. Gently rolled
in above 10 kHz, the ribbon reaches full
contribution from 15 kHz to well beyond
30 kHz, far above the audible range.
Equipped with a rear chamber fitted
with rigid bracing, the ribbon is shielded
from the disruptive influence of the
woofers. The DALI ribbon tweeter is a
true master in horizontal distribution of
high frequencies, and a superb partner
for the soft dome tweeter’s unique
ability to reproduce frequencies from
2.5 kHz upwards.
Both the soft dome and the ribbon
tweeter are free of artefacts, e.g.
resonances and high Q peaks within
their working range. The Hybrid Tweeter
Module features an extremely smooth
and wide horizontal dispersion - one
of our sound design trademarks. Even
the detailing of the faceplate of the
tweeter module is designed for optimal
horizontal dispersion.
