Visaton 8051 Visaton SC 4.9FL 8Ohm

4 x 9 cm (1.6 "x 3.5") broadband loudspeaker with wooden membrane and a stable plastic basket. Flat and light construction thanks to neodymium. The interaction of the individual components ensures an extremely linear transmission curve down to comparatively very low frequencies so that the applications of the loudspeaker can also be extended to miniature hi-fi boxes.
