SC 4.7 ND - 8 Ohm


Art. No. 8048


Magnetically shielded 4 x 7 cm (1.6" x 2.8") 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
  • TVs
  • Control speaker for electronic devices

Attributes

  • Moisturised cone
  • Metal basket
  • Magnetically shielded
