Description

The ND1030 1-inch exit high frequency compression driver has been designed for use in high quality two-way audio systems.
The
ND1030 exhibits a constant slope response from 1.5kHz to 18kHz with a
uniform and smooth roll-off. With a 900Hz free air resonance frequency,
the ND1030 can easily be cut-off at 1800Hz and is capable of 60W
continuous power handling with a 1800Hz pink-noise signal, and a 6dB
crest factor with a minimum 12dB/oct crossover slope.
Equipped
with unique Phase Plug architecture, the ND1030 has been designed to
give a smooth coherent wavefront at the horn entrance in the whole
working frequency range, as well as high level manufacturing
consistency. The phase plug design with its short openings and high
flare rate value assures low distortion and demonstrates remarkable
improvements in mid-high frequency reproduction.
The ND1030
titanium diaphragm assembly, with its ellipsoidal suspension shape,
exhibits a constant slope response from 1kHz to 18kHz with uniform
smooth roll-off behavior. An edge-wound aluminum voice coil, wound on
proprietary 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. This feature enables
proper energy transfer control from the voice coil to the dome in real
working conditions. Moreover, this proprietary former material is also
suitable for use in higher moisture content environments.
By
careful use of elementary pieces of neodymium magnets, Eighteen Sound
engineers have developed a powerful neodymium magnet assembly capable
of reaching 18KGauss in the gap within a compact and lightweight
structure.
