Product information "Vifa BC25SC-55/04 Neodynium"
The Vifa BC25SC55-40 1" 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 neodymium magnet motor, providing enhanced cooling of the voice coil. The tweeter comes with a compact faceplate with recessed mounting holes, complete with sealing gasket which helps in reducing vibration between baffle and driver. A finned heat sink has been added for improved power handling.
