This BC family tweeter features a 8 ohm 25 mm voice coil, a damped fabric dome for smooth frequency response performance, and ferrofluid in the gap of the ferrite 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.
