NEW Visaton G20SC8 0.8" Magnetically Shielded Textile Dome Tweeter 8 Ohm

Visaton
Part #292-7804  
Model: GS 20 SC

The Visaton G 20 SC is a high-end 20 mm (0.8") textile dome tweeter designed for precise high-frequency reproduction above 3,000 Hz. Its optimized dome shape and damping felt on the pole piece ensure a balanced frequency response without resonance, providing excellent omnidirectional sound distribution. The magnetically shielded design allows for integration near video equipment without interference. The powerful magnet drive and ferrofluid-cooled voice coil contribute to high efficiency and substantial power handling, making it suitable for high-fidelity audio applications.

Key Features
  • Frequency response from 1,200 to 30,000 Hz for extended high-frequency reproduction
  • Resonance frequency at 1,890 Hz contributing to clear high-frequency performance
  • Peak power handling of 140 W with a 12 dB/octave high-pass filter at 2,000 Hz for robust performance
  • Opening angle of 180° at 8,000 Hz for wide sound dispersion
  • Magnetically shielded design for safe integration near video equipment
