The BC family of tweeters features a damped fabric dome for smooth frequency response performance and ferrofluid in the gap of the NdFeB magnet motor,providing enhanced cooling of the voice coil. BC tweeters come with a compact faceplate with recessed mounting holes,and for this driver a finned heat sink has been added to improve power handling.
