  • Excellent thermal exchange
The ND1460T 1.4-inch exit neodymium high frequency compression driver has been designed for high level sound systems application.
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 1.2kHz. The diaphragm assembly is made by joining the former directly to the diaphragm 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 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.
By careful use of elementary pieces of neodymium magnets, the powerful neodymium magnet assembly is able to reach 19 KGauss in the gap in a compact and lightweight assembly.
The ND1460T motor structure, throughout the precisely coherent aluminum phase plug with 3 circumferential slots and the 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, lowering midrange frequencies distortion and improving frequency response figure.
The custom designed O-ring creates a tight seal between the plate and the cover assuring air chamber loading.
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.
A special treatment has been applied to the magnet and the top and back plates of the magnetic structure which make the driver more resistant to the corrosive effects of salts and oxidization.
