The ND1TP is a 1 inch exit neodymium high frequency compression driver specifically designed for high quality applications.Equipped with proprietary phase plug architecture, the ND1TP has been developed to give high level manufacturing consistency and smooth coherent wavefront at horn entrance over all the working frequency range. This phase plug design, with its short openings and high flare rate value assures low distortion and remarkableimprovements in mid-high frequency reproduction.With its Pen suspension, the titanium diaphragm assembly exhibits constant slope response from 1kHz to 18kHz with uniform smooth roll-off behavior. An edge-wound aluminum voice coil, wounded on proprietary treated Nomex, completes diaphragm assembly. Thanks to its physical properties, the proprietary treated Nomex former shows 30% higher value of tensile elongation at working operative temperature (200°C) when compared to Kapton.A copper ring on the pole piece reduces inductance above 10 kHz improving phase and impedance linearization.The ability to perform properly under inclement weather conditions is a key-point of the Eighteen Sound philosophy. A special treatment is applied to the magnet and the top and back plates of the magnetic structure making the ND1TP driver more resistant to the corrosive effects of salts and oxidization than any other treatment used by any other manufacturer.
