Description
The RCF ND950 1.4, Pure Titanium Compression Driver is an ultra-compact size, high performance, high power handling 4.0-inch diaphragm compression driver with a 1.4-inch exit throat. The high-power neodymium magnet guarantees the perfect control of the dome assembly’s moving mass. This leads to higher efficiency, better transient response and diminishes high frequency distortion modes. A thin copper ring is precision pressed on to the pole piece in order to modify and lower the inductance characteristics of the magnetic circuit and voice coil providing a controlled extension of the acoustic frequency response. The ND950 1.4 features a 0.05 mm thick pure titanium dome in combination with a high strength Mylar suspension. The voice coil assembly is designed using a high strength, high temperature Kapton voice coil former and edge wound copper clad aluminium wire. The ND950 1.4 features a 4-slot, optimized geometry, phase plug design. Extended computer assisted mathematical modelling and testing has resulted in a geometry that provides a balanced acoustic performance controlling and lowering air distortion and maximizing output.
