Key Features:

• 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.
