Produktinformationen "18s ND1070 8 Ohm"

The ND1070 1-inch exit high frequency compression driver has been designed for use in high quality
two-way audio systems. Equipped with Proprietary Phase Plug architecture, ND1070 shows high level
manufacturing consistency and a smooth coherent wavefront at the horn entrance across the whole
working frequency range. With its short openings and high flare rate value, this phase plug
configuration assures low distortion and demonstrates remarkable improvements in mid-high
frequency reproduction. The ND1070 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 1.6 kHz. 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. This
feature enables proper energy transfer control from the voice coil to the dome in real working
conditions. Moreover, this proprietary former material is also suitable for use in high moisture
content environments. A copper ring on the pole piece reduces inductance above 10 kHz, improving
phase and impedance linearization. By careful use of elementary pieces of neodymium magnets,
Eighteen Sound engineers have developed a powerful neodymium magnet assembly capable of
reaching 18KGauss in the gap within a compact and lightweight structure. 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 in Eighteen Sound philosophy.
A special treatment has been applied to the magnet and the top and back plates of the magnetic
structure making the driver more resistant to the corrosive effects of salts and oxidization. This
treatment is more effective than any other treatment used by other manufacturers.
