In addition to the next-gen titanium diaphragm of the standard ND3ST version, our TPM nitrate coat is applied, doubling the titanium stiffness and avoiding spurious resonances at very high frequencies, assuring a 3rd harmonic distortion lower than 0.05% over the whole working range.
The ND3SN neodymium magnet assembly has been designed to obtain 21KGauss in the gap for major benefits in transient response. The motor structure, throughout the precisely coherent proprietary designed metal alloy phase plug with 4 circumferential slots and copper ring on the pole piece, reduces inductance effect and distortion.
The diaphragm kit self-centering design allows high precision mounting and at the same time makes very easy the servicing procedure.
The ability to perform properly under inclement weather conditions is
a key point of the Eighteen Sound philosophy. Hence, a special
treatment is applied to the magnet and the top and back plates of the
magnetic structure in order to make the driver more resistant to the
corrosive effects of salts and oxidization. This treatment is more
effective than any other coating commonly used.
