Art. No. 2003

Visaton FRS8 - 4 Ohm Full Range Speaker

Characteristics and Sound Properties
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:-
- Control speaker for electronic devices
- Ceiling-mounted speakers in railway carriages and buses
- Mini Hi-fi systems
- Model construction

Attributes:-
- Moisturised cone
- Metal basket
