Description
The ND2060A 2 inch exit neodymium HF compression driver has
been designed for high quality sound systems application. The
ND2060A diaphragm assembly is composed by an aluminum dome sandwiched
to a proprietary treated PEN (polyethylene naftalate) suspension. This
design maintains low resonance and lowers the minimum crossover point
value at 800 Hz. The composite diaphragm assembly is made by an
aluminum dome strongly joined to the PEN suspension, in order to assure
unmatched transient response. The lower density of the aluminum and PEN
structure permits higher levels of sensitivity, especially in the
mid-high frequency range. A bended former edge-wound
aluminum 75mm voice coil completes the diaphragm assembly. The
proprietary treated Nomex former material shows 30% higher value of
tensile elongation at working operative temperature (200°C) when
compared to Kapton. Moreover, Nomex is suitable to work also in higher
moisture contents environments. The bended former is joint in a
sandwich configuration between PEN suspension and the aluminum dome,
assuring extended frequency energy transfer for improved response
linearity and unparallel reliability. Through careful use of
elementary pieces of neodymium magnets, Eighteen Sound engineers have
developed a powerful neodymium magnet assembly able to reach 19 KGauss
in the gap in a compact and lightweight structure. 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 were 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
that allows to obtain a lower power compression value. 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. The special coating applied to the
magnet and the top and back plates of the magnetic structure makes the
ND2060A compression driver resistant to the corrosive effects of salts
and oxidization.
