Accuton C25-4-158

Beschreibung

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

A proprietary clamping technology allows easy mounting and adaptation to various front panel designs. Since the break-up frequency of the diaphragm is above the audible range and is well damped, no diaphragm cutouts are required. A unique FEA-optimized underhang 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  in  an application above 2000 Hz.
