Produktinformationen "Eighteensound ND1085 8 Ohm"
The ND1085 1 inch exit neodymium high frequency compression driver has
been designed for situations where the highest quality is required.
Equipped with proprietary Phase Plug architecture, the ND1085 has been
designed to give high level manufacturing consistency and a smooth
coherent wavefront at the horn entrance across the whole working
frequency range. The phase plug short openings and high flare rate value
assure low distortion, showing remarkable improvements in mid-high
frequency reproduction. The diaphragm is made with a proprietary
treated Polyethylene material (PEN). Thanks to its superior dimensional
stability up to 160°C, PEN is able to maintain constant behavior during
its whole working life. Moreover, thanks to its high value of
elasticity modulus (50% higher than Mylar and 100% higher than
polyimide), it is capable of superior transient and intermodulation
distortion response. The flat suspension shape has been designed to
maintain low stiffness and low mid band distortion and response. The
edge-wound aluminum voice coil, wound on custom treated Nomex, completes
the diaphragm assembly. Nomex shows a 30% higher value of tensile
elongation at a working operative temperature (200°C) when compared to
Kapton. Moreover, this proprietary treated former material is also
suitable for use in high moisture content environments. The powerful
neodymium magnet assembly has been designed to obtain 20 KGauss in the
gap giving major benefits in transient response. 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. 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. The ability to perform
properly under inclement weather conditions is a key feature of the
Eighteen Sound philosophy. Hence, in addition, a special treatment has
been applied to the magnet and the top and back plates of the magnetic
structure making the ND1085 driver more resistant to the corrosive
effects of salts and oxidization.
