Visaton G 20 SC
Magnetically shielded 20 mm (0.8") High-end textile dome unit for use at tweeter frequencies of 3,000 Hz and above. The optimised dome shape and damping felt on the pole piece ensures a very balanced frequency response without resonance and excellent omnidirectional sound distribution. The powerful magnet drive and ferro-fluid cooled voice coil guarantee both high efficiency and excellent power handling capabilities.
