FRS 8 4 OHM
FRS 8 4 OHM Art. No. 2003 8 cm (3.3") HiFi fullrange driver. Linear frequency response between 200 and 20.000 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 busses - Mini fi-fi systems - Model construction
