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 B 80 8 OHM is ideal for small high-end shelf speakers or as a mid-high-range unit in high-end multi-way speakers.
