18s ND2060 8 Ohm

The ND2060 2-inch exit neodymium high frequency compression driver has been designed for high
level sound systems application. Its 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's design assures extended frequency energy transfer for improved response
linearity and unparallel reliability. This feature facilitates proper motion control of the dome in real
working conditions. A proprietary treated Nomex former is used as 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
big innovation in ND2060 consists of its magnetic architecture. By careful use of elementary pieces
of neodymium magnets, Eighteen Sound engineers have developed a powerful neodymium magnet
assembly able to reach 19KGauss in the gap in compact and lightweight structures. The motor
structure, throughout the precisely coherent phase plug with 3 circumferential slots and copper ring
on the pole piece, reduces inductance effects 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 has been
applied to the magnet and the top and back plates of the magnetic structure which make the driver
more resistant to the corrosive effects of salts and oxidization. This treatment is more effective than
any other treatment in use by other manufacturers.
