The BC family of tweeters features a damped fabric dome for smooth frequency response performance and ferrofluid in the gap of the ferrite magnet motor,providing enhanced cooling of the voice coil. BC tweeters come with a compact faceplate with recessed mounting holes,complete with sealing gasket which helps reduce vibration between baffle and driver.
