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.
Features:
- 4.0 inch, Kapton former, edge wound aluminium voice coil
- 1.4" throat
- 280 Watt continuous program power handling
- 110 dB Sensitivity
- 500 Hz –20 KHz Frequency range
- Titanium dome, Polymide surround
- 4 slot phase plug
- The minimum size 4" driver available
Applications:
With a wide frequency response range (500 Hz – 20.000 Hz) and 280 Watt power handling, the ND940 is the ideal driver for heavy duty professional applications.
