SC 5.9 ND - 8 Ohm

Art. No. 8056

Magnetically shielded 5 x 9 cm (2" x 3.5") fullrange driver with good efficiency and balanced frequency response with a clear highrange reproduction. Extremely small size due to a neodymium magnet system. Applicable as built-in speaker in TV's and PC's with very small mounting space.

Typical applications
Video monitoring screens
Monitoring speaker for electronic devices
  • Moisturised cone
  • Metal basket
  • Magnetically shielded
