FR 58 - 8 Ohm

Art. No. 2205

5.8 cm (2.3") full-range speaker with coated paper cone, rubber surround, squared metal basket with 4 mounting holes and rubber gasket. Very linear and wide frequency response and low resonant frequency provide a wide range of apllications, including Hi-Fi-applications.
