Visaton SC 4.9 FL 8 Ω
4 x 9 cm (1.6" x 3.5") full-range speaker with wooden cone and stable plastic basket. Flat and lightweight design because of neodymium. The cooperation of the separate components leads to a very linear frequency response up to deepest frequencies by way of comparison, so that the loudspeaker can be also used in miniature hi-fi speakers. *) IP protection class for front side when built into a sealed enclosure
