General Description
The ND1460 1.4 inch exit neodymium high frequency compression
driver has been designed for use in high quality sound systems.
The pure 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
using its upper bend edge. In comparison with a usual straight
former joint, the driver design assures extended frequency energy
transfer giving 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 high
moisture content environments.
By carefully using elementary pieces of neodymium magnets,
Eighteen Sound engineers have developed a powerful neodymium
magnet assembly capable of reaching 19KGauss in the gap in
compact and lightweight structures. 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 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.
The ability of equipment to perform properly under inclement
weather conditions is a key feature of the Eighteen Sound
philosophy. Hence, a special treatment is applied to the magnet and
the top and back plates of the magnetic structure which increases
the ND1460 resistance to the corrosive effects of salts and
oxidization. This treatment is more effective than any other
treatment in use today.
