SKU: V-8051-SC49FL SC 4.9 FL - 8 Ohm

Visaton Speaker Driver - SC 4.9 FL - 8 Ohm Full Range
Art. No. 8051

Visaton SC4.9FL - 8 Ohm Full Range

Characteristics and Sound Properties
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 rating when rear is sealed.
