Description

The ND1050 one inch exit high frequency compression driver is designed
for high quality applications, where size is a critical issue.
ND1050
high flux ultra compact magnetic assembly architecture, achieves the
remarkable 1,9 Tesla value in the gap containing the external size in
75mm – 3 inches – making this HF driver a benchmark in its category.
Equipped
with Eighteen Sound proprietary Phase Plug architecture, the ultra
compact ND1050 ensures a coherent wavefront at the horn entrance over
all the working frequency range. The radial – tangerine phase plug
design with short openings and high flare rate value assures low
distortion and remarkable improvements in mid-high frequency
reproduction.
The transducer diaphragm assembly is composed of a
titanium dome sandwiched to a proprietary treated polyester suspension.
This design maintains low resonance and lowers the minimum crossover
point value to 1.6kHz.
An edge-wound aluminum voice coil, wounded on
proprietary treated Nomex, completes diaphragm assembly. Thanks to its
physical properties, the proprietary treated Nomex former shows 30%
higher value of tensile elongation at working operative temperature
(200?C) when compared to Kapton. Moreover, this material is suitable to
work also in higher moisture contents environments.
The ability to
perform properly under inclement weather conditions is a key-point of
the Eighteen Sound philosophy. The special treatment applied to the
magnet and the top and back plates of the magnetic structure makes the
driver more resistant to the corrosive effects of salts and oxidization
than any other treatment used by other manufacturers.
