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.
