SKU: V-2412-FRS7A FRS 7 A - 8 Ohm

Visaton Speaker Driver - FRS 7 A - 8 Ohm Full Range
Art. No. 2412

Visaton FRS7A - 8 Ohm Full Range Speaker

Characteristics and Sound Properties
6.5 cm (2.5") fullrange speaker with balanced frequency response and very good highs. Especially suitable as built-in speaker for music reproduction and as driver for 100 V network column speakers. Outstandingly high efficiency compared to the small size.

Equivalent to model FRS 7 - 8 Ohm, but with connectors 2.8 x 0.8 mm (+) and 2.8 x 0.8 mm (-).

Typical applications:
- Narrow network column speakers
- Control speaker for electronic devices
- Model construction
- Electronic musical instruments

Attributes:
- Water proof cone
- Metal basket
- 100 °C temperature resistant
