Vifa BC25SC-08/04

Vifa BC25SC-08/04 25mm Softdome Tweeter

This BC family tweeter features a 4 ohm 25 mm voice coil, a damped fabric dome for smooth frequency response performance, and ferrofluid in the gap of the NdFeB motor, providing enhanced cooling of the voice coil. The tweeter comes with a compact faceplate with recessed mounting holes.A finned heat sink has been added for improved power handling.
