Eighteen Sound ND3T 16 Ohm 1.4″ 110W Compression Driver

Eighteen Sound ND3T 16 Ohm 1.4″ 110W Compression Driver

Product description:

Eighteen Sound ND3T 1.4 inch exit Natural Sound neodymium high frequency compression driver has been designed for high level sound systems application.
The unit has been designed to fulfill tight geometrical requirements, thanks to its ultra compact 109mm overall diameter.
The titanium diaphragm is produced in house and has been developed to assure unmatched transient response.
The diaphragm assembly is made by joining the former directly to the titanium dome on its upper bend edge. In comparison with a usual straight former joint, the driver’s design assures extended frequency energy transfer for improved response linearity and unparallel reliability.
This feature facilitates proper motion control of the dome in real working conditions.
A proprietary treated Nomex former is used as Nomex shows a 30% higher value of tensile elongation at a working operative temperature (200°C) when compared to Kapton.
Moreover, this proprietary former material is also suitable for use in higher moisture content environments.
