The ND850 1.4 is a high frequency performance 3-inch diaphragm compression driver with a 1.4-inch exit throat featuring several state of the art technologies.
The diaphragm is precision formed from 0.05mm thick pure titanium.
The suspension is based on a vented and damped design in order to provide low distortion.
Voice coil assembly is designed using high temperature kapton former.
