Produktinformationen "18s ND1460A 8 Ohm"

The ND1460A 1.4 inch exit neodymium HF compression driver has been designed for high level sound
systems application. The diaphragm assembly is composed by an aluminum dome sandwiched to a
proprietary treated polyester suspension. This design maintains low resonance and lowers the
minimum crossover point value at 800Hz. 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 jointed 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. The ability
to perform properly under inclement weather conditions is a key-point of Eighteen Sound philosophy.
The special coating applied to the magnet and the top and back plates of the magnetic structure
makes the ND1460A compression driver resistant to the corrosive effects of salts and oxidization.
