General Description
The HD2080T 2-inch exit high frequency compression driver has
been designed for use in high quality installed audio systems, where
weight is not the key issue.
The motor structure, throughout the precisely coherent phase plug
with 3 circumferential slots and copper ring on the pole piece,
reduces inductance effects and distortion. Four top plate air ducts
have been designed to act as a loading chamber for the diaphragm,
implementing mid band distortion and response figures.
The HD2080T 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 1,2kHz.
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 HD2080T powerful ceramic magnet assembly has been designed
to obtain 16KGauss in the gap.
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.
