C25-6-013 Ceramic Tweeter
The C25-6-013 is a 1 inch tweeter with ultra hard ceramic dome in a 82 mm frontplate. Anti-resonant cutout fills in the ceramic dome provide for damping of the 37 kHz dome resonance. An underhung motor design with vented aluminium voice coil former guarantees low energy storage and excellent heat transfer. The soft fabric surround and ferrofluid with high viscosity center the moving parts with distinctive linearity. We recommend our C25-6-013 in an application above 2500 Hz.
