Moteurs 1.4"

2.5-inch Diaphragm, 1.4-inch Exit Throat / Pure Titanium Compression Driver 180W continuous program power handling Frequency range: 700Hz - 20kHz 3-slot optimized geometry phase plug Titanium diaphragm Copper inductance ring for extended response Vented, damped, low distortion suspension system Neodymium magnet assembly

The ND940 is a ultra compact size, high performance, high power handling 4.0-inch diaphragm compression driver with a 1.4 inch exit throat. 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 voice coil assembly is designed using a high strength, high temperature Kapton® voice coil former and edge wound copper clad aluminium wire directly joined to the diaphragm by RCF proprietary Direct Drive kapton technology. The ND940 features a 4-slot, optimised 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.
