This BC family tweeter features a 8 ohm 25 mm voice coil, a damped fabric dome for smooth frequency response performance, a bucking magnet for higher sensitivities, and ferrofluid in the gap of the NdFeB motor, providing enhanced cooling of the voice coil. The tweeter comes with a bucking magnet and a compact faceplate with recessed mounting holes, greatly increasing the sensitivity of the tweeter.A finned heat sink has been added for improved power handling.
