For its size, the BC25SC08-04 1" silk dome tweeter is an impressive performer. A semi-horn loaded faceplate helps to control dispersion increasing efficiency to 98 dB @ 2.83V/1m. The motor includes a neodymium magnet with ferrofluid and cooling fins allowing the 1" voice coil to handle up to 100 watts of power making this a highly dynamic tweeter. In addition, the smooth frequency response allows for an easy transition to a midrange in higher efficiency compact systems.
