SC 5.9 ND - 4 Ohm

Art. No. 8055

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
TVs
Monitoring speaker for electronic devices
