Peerless BC25SC55-04 Tweeter

£13.84

25mm Dome Tweeter, 4Ω.

This smooth sounding tweeter features a 4 ohm 25 mm voice coil, high energy Neodymium magnet assembly, a damped textile dome and ferrofluid in the magnetic gap for enhanced cooling of the voice coil. The BC25SC55-04 has a compact cropped faceplate (70mm diameter, 54mm across flats) with recessed mounting holes, and comes complete with a foam sealing gasket to reduce vibration. A finned heatsink aids cooling and results in high power handling for a driver of this size.
