General Description
The HD1050 one inch exit high frequency compression driver has
been designed for use in high quality audio systems.
Equipped with Eighteen Sound proprietary Phase Plug architecture,
the HD1050 has been designed to give high level manufacturing
consistency and smooth coherent wave front at the horn entrance
across the whole working frequency range. The phase plug with its
short openings and high flare rate value assures low distortion and
demonstrates remarkable improvements in mid-high frequency
reproduction.
The diaphragm assembly is composed of a titanium dome
sandwiched to a proprietary treated polyester suspension unit. It has
been designed to maintain low resonance, lowering the minimum
crossover point value at 1,6kHz. An edge-wound aluminum voice
coil, wound on proprietary treated Nomex, completes the diaphragm
assembly. Thanks to its physical properties, the proprietary treated
Nomex former has 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 to for use in higher
moisture content environments.
The HD1050 powerful ceramic magnet assembly has been designed
to obtain 16 KGauss in the gap and within a compact ferrite motor
structure.
