80mm Midrange Speaker

80mm Midrange Speaker

The center channel uses an 80mm metal-cone midrange speaker, placed in the center of the instrument panel, powered by a high-strength neodymium magnet. The center channel is key to replicating the feeling of being at a live performance. It places the primary vocalist or performer in a central position - at center stage. In addition, this midrange speaker blends the audio imaging with the right and left front speakers to help expand the overall soundstage.
