8 cm (3.3") HiFi fullrange driver. Linear frequency response between 200 and 20000 Hz. Suitable for surround 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 busses
- Mini Hi-fi systems
- Model construction
Attributes:
- Moisturised cone
- Metal basket
