Back to Overview
The C51-6-286 is a 2 inch tweeter with ultra hard ceramic dome in a 86 mm body. A proprietary clamping technique provides easy mounting and adapting to individual frontplates. As the dome breakup is above the audible range and well damped, no dome cutouts are required. A unique FEA optimized 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 designed soft fabric surround centers the moving parts with improved linearity.
We recommend our C51-6-286 in an application above 800 Hz.
