Key Features:

• The (Eighteen) 18 Sound 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.
