C51-6-286
Features include: ultra hard 51mm ceramic dome, 86mm Cell Concept body, discrete clamping system for secure mounting to baffles. The dome breakup mode is above audibility and well damped. A unique FEA optimised underhung motor design with vented titanium voice coil former and double neodymium magnet guarantees low energy storage, excellent heat transfer and high excursion capability for low power compression and ultra low distortion. The new design soft fabric suspension centers the moving parts with improved linearity.
The C51-6-286 is an esoteric, high end midrange drive unit : 800 Hz - 6Khz.
