FRS 8 - 8 Ohm

Art. No. 2004

8 cm (3.3") HiFi fullrange driver. Linear frequency response between 200 and 20000 Hz. Suitable for sur-round effect speakers, mini sub/sat systems. Due to the small size very suitable for model construction and as control speaker for electronic devices.

Typical applications
Monitoring speaker for electronic devices
Ceiling- mounted speakers in railway carriages and busses
Mini Hi-fi systems
Model construction
  • Moisturised cone
  • Metal basket
