Description
The ND2080 2-inch exit high frequency compression driver has been designed for high quality
sound systems application. The titanium diaphragm is produced in house and has been developed
to assure unmatched transient response. The diaphragm assembly is made by joining the former
directly to the titanium dome on its upper bend edge. In comparison with a usual straight former joint,
the driver design assures extended frequency energy transfer for improved response linearity and
unparallel reliability. This feature allows proper motion control of the dome in real working conditions.
A proprietary treated Nomex former is used as 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 higher moisture content environments. The ND2080 powerful neodymium
magnet assembly has been designed to obtain 22KGauss in the gap for major benefits in transient response.
The motor structure, throughout the precisely coherent phase plug with 3 circumferential slots and copper
ring on the pole piece, reduces inductance effect and distortion. Four top plate air ducts have been designed
to act as a loading chamber for the diaphragm, implementing mid band distortion and response figures.
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. Due to the increasing
use of high power audio systems at outdoor events or in marine environments, the ability of equipment to
perform properly under inclement weather conditions is a key feature of Eighteen Sound philosophy. Hence,
a special treatment is 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.
