The Esotec MD 102 soft-dome tweeter features a special coating that yields an extended high frequency response free of distortion. The 28mm (1.1 inch) diameter surface area is approximately 60% greater than that of conventional car audio tweeters, while its optimized dome geometry provides improved dispersion and exceptional off axis performance. 
The coating also serves to eliminate any high frequency break-ups, while providing improved damping. The MD 102 tweeter rear chamber is also sealed and acoustically damped to eliminate high frequency distortion that could be caused by back-wave reflections, while ferrofluid cooling adds damping and additional power handling. For the most authentic and dynamic high-frequency reproduction - powerful Neodymium - one of the most efficient but also most expensive magnetic materials for loudspeaker construction is used in the tweeter magnet systems. The MD 102 features an aluminum voice coil, a Dynaudio hallmark, which has been improved via an increased coil height with additional windings to allow an increased range of linear excursion within the magnetic field. As a result of the low moving mass of the new voice coil, a higher maximum output level and increased dynamics are achieved, while the frequency range has been expanded, thus allowing a better integration with the upper midrange frequencies to deliver a more natural sound with an open, detailed and incredibly transparent reproduction of the high frequencies.
