Produktinformationen "Eighteensound ND1090 8 Ohm"
The ND1090 1 inch exit neodymium high frequency compression driver has
been designed for situations where the highest quality is required.
Equipped with unique Phase Plug architecture, the ND1090 has been
designed to give high level manufacturing consistency and a smooth
coherent wavefront at the horn entrance across the whole working
frequency range. The phase plug short openings and high flare rate value
assure low distortion, showing remarkable improvements in mid-high
frequency reproduction. The ND1090 diaphragm assembly is composed of a
titanium dome sandwiched to a proprietary treated polyester suspension.
This design maintains low resonance and lowers the minimum crossover
point value to 1.6kHz. An edge-wound aluminum voice coil, wound on
proprietary treated Nomex, completes the diaphragm assembly. Nomex shows
a 30% higher value of tensile elongation at a working operative
temperature (200°C) when compared to Kapton. Moreover, this proprietary
former material is also suitable for use in high moisture content
environments. The powerful neodymium magnet assembly has been designed
to obtain 20 KGauss in the gap giving major benefits in transient
response. A copper ring on the pole piece reduces inductance above 10
kHz, improving phase and impedance linearization. The custom designed
O-ring creates a tight seal between the plate and the cover assuring air
chamber loading. Excellent heat dissipation and thermal exchange are
guaranteed by the direct contact between the magnetic structure and the
aluminum cover which leads to a lower power compression value. The
ability to perform properly under inclement weather conditions is a key
feature of the Eighteen Sound philosophy. Hence, in addition, a special
treatment has been applied to the magnet and the top and back plates of
the magnetic structure making the ND1090 driver more resistant to the
corrosive effects of salts and oxidization. This treatment is more
effective than any other treatment used by other manufacturers.
