Visaton SC 4 ND 4 Ω
Magnetically shielded HiFi titanium dome tweeter for the high-frequency range above 2000 Hz. Due to the highly damped sypronyle surround the frequency response is free from partial oscillations. The ferrofluid-filled air-gap provides a high power handling. Magnetic shielding and compact dimensions thanks to the use of a neodynium magnet system. The latter allows real D`Appolito baffle designs.
