FRWS 5 R - 8 Ohm

Art. No. 2212

5 cm (2") fullrange speaker with round basket, soft surround and special light weight cone. Balanced frequency response above 250 Hz, brilliant highs and good omnidirectional sound distribution. Suitable as midrange driver in column speaker systems for HiFi applications as well as for 100 V sound reinforcement systems. Due to the small size also suitable for model construction and as control speaker for electronic devices.

Typical applications
Very narrow network column speakers
Monitoring speaker for electronic devices
Model construction
  • Moisturised cone
  • Metal basket
