Visaton Speaker Driver - B 80 - 8 Ohm Full Range Loudspeaker
Art. No. 1261
Characteristics and Sound Properties
8 cm (3.3") high-end full-range loudspeaker with excellent balanced response characteristics. Due to perfect accordance
of the coated paper cone, the rear ventilated damper and the phase plug, as well as the strong and lightweight neodymium
magnet, an extremely well-balanced frequency response with very low harmonic distortion and lowest possible mechanical losses
comes into being. The B80 8 Ohm is ideal for small high-end shelf speakers or as a mid-high-range unit in high-end multi-way
speakers.
