Material & Fabrication Ceramic

Alpha corundum or saphire is one of the best material choices for speaker cones. It is light, yet very stiff and if it is made by the electrochemical process we have invented in the 80’s of last century, it also has a quite nice internal damping factor, all that a speaker membrane is supposed to have.

C30-6-358

The C30 - 6 - 358 is a 1.2 inch tweeter with ultra hard ceramic dome in a 58 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 aluminium 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 around 0.07% @ 2.83V and 0.5% max. @ 110dB. The new designed soft fabric surround centers the moving parts with improved linearity. We recommend an application above 1800 Hz.
