Accuton C25-4-158

Description

The Accuton C25-4-158 is a tweeter with an ultra-hard 25 mm ceramic cone in a 58 mm aluminum housing.

A proprietary clamping technique enables easy mounting and adaptation to various front panel designs. As the break-up frequency of the cone is above the audible range and well damped, no cone cut-outs are required. A unique FEA-optimized underhung design with vented titanium voice coil former and double neodymium magnet guarantees low energy storage, excellent heat transfer and high excursion for low compression and extremely low distortion. The newly designed soft fabric surround centers the moving parts with improved linearity.

We recommend our Accuton C25-4-158 for applications above 2000 Hz.
