Produktinformationen "18s ND1018BT 8 Ohm"

The ND1018BT 1-inch exit high frequency compression driver is designed for high quality two-way
systems applications. Equipped with proprietary Phase Plug architecture, the ND1018BT compression
driver offers high level manufacturing consistency and smooth coherent wavefront at horn entrance
over all the working frequency range. The phase plug design with short openings and high flare rate
value assures low distortion and remarkable improvements in mid-high frequency reproduction. With
its ellipsoidal suspension shape, the ND1018BT titanium diaphragm assembly exhibits constant slope
response from 1kHz to 18kHz with uniform smooth roll-off behavior. An edge-wound aluminum voice
coil, wounded on proprietary treated Nomex, completes diaphragm assembly. Thanks to its physical
properties, the proprietary treated Nomex former shows 30% higher value of tensile elongation at
working operative temperature (200°C) when compared to Kapton. Moreover, this proprietary former
material is suitable to work also in higher moisture contents environments. Through careful use of
elementary pieces of neodymium magnets, Eighteen Sound engineers have developed a powerful
neodymium magnet assembly able to reach 18 KGauss in the gap in compact and lightweight
structure. 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. For the increase in use of high power audio systems at outdoor
events or in marine environments, the ability to perform properly under inclement weather conditions
is a key-point of the Eighteen Sound philosophy. In addition, the special treatment applied to the
magnet and the top and back plates of the magnetic structure makes the driver more resistant to
the corrosive effects of salts and oxidization.
