Moteurs 1.4"

3-inch Diaphragm, 1.4-inch Exit Throat / Pure Titanium Compression Driver 220W continuous program power handling Frequency range: 500Hz - 20kHz Direct Drive Voice Coil Assembly 3-slot optimized geometry phase plug Aluminium rear cover featuring an advanced vented fin heat dissipation design Copper inductance ring for extended response Vented, damped, low distortion, variable profile suspension system

The CD850 1.4 is a high performance 3.0-inch diaphragm compression driver with a 1.4 inch exit throat featuring several state of the art technologies. The diaphragm are precision formed from pure titanium. The suspension is based on a vented and damped design in order to provide low distorsion. Voice coil assembly is designed using high temperature kapton former.

2.5-inch Diaphragm, 1.4-inch Exit Throat / Pure Titanium Compression Driver 180W continuous program power handling Frequency range: 700Hz - 20kHz Direct Drive Voice Coil Assembly 3-slot optimized geometry phase plug Aluminium rear cover featuring an advanced vented fin heat dissipation design Copper inductance ring for extended response Vented, damped, low distortion, variable profile suspension system

The ND640 is a high performance 2.5-inch diaphragm compression driver with a 1.4 inch exit throat featuring the smallest size of the art technology. The diaphragm are precision completely formed from pure titanium. Voice coil assembly is designed using high temperature kapton former and it is joined to the diaphragm by RCF proprietary Direct Drive kapton technology. Diaphragm suspension is designed by extensive FEM study for low distortion and low frequency range extension.

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.
