18 Sound HD2080T 2" High Frequency Compression Drive 200 Watts Bolt-On 8-Ohm

Key Features

  • 109 dB SPL 1W / 1m average sensitivity

  • 2 inch exit throat

  • 3 inch edgewound aluminum voice coil

  • 200W program power handling

  • Polyethilene - Titanium diaphragm assembly

  • Copper shorting ring on pole pieces

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.
