Produktinformationen "18s NSD4015N 8 Ohm"

NSD4015N is a 1.5 inch exit, 4" voice coil neodymium compression driver has been designed for
extremely high quality sound systems application. The titanium nitride coated dome - so called TPM
True Piston Motion technology - dramatically improves stiffness with obvious benefits in transient and
intermodulation distortion response. With its very high value of elasticity modulus (six times higher
than standard titanium), the ultra-thin nitride coated film applied both sides of the dome doubles the
treated dome stiffness. The piston frequency range motion extends then by 25% when compared to
regular titanium diaphragm, showing a predictable, ideal frequency response decay and avoiding
top-end spurious resonances. This results in a more natural sound character up to the top end part
of the spectrum. The nitride-free ellipsoidal suspension shape has been designed to maintain
constant titanium stiffness, assuring a 3rd harmonic distortion lower than 0.05% over the whole
working frequency range. The NSD4015N extremely powerful neodymium magnet assembly has been
designed to obtain 22 KGauss in the gap for major benefits in transient response. The motor
structure, throughout the precisely coherent phase plug with 4 circumferential slots and copper ring
on the pole piece, reduces inductance effect 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 gives a lower
power compression value. A special epoxy coating is applied to the ring magnet and the top and
back plates of the magnetic structure making the driver more resistant to the corrosive effects of
salts and oxidization.
