英国QUAD(国都) ESL-2812 旗舰豪华版静电扬声器

ESL 2812 is the first model in the ESL Series. Quad's patented panel technology results in a combination of the speed and accuracy only possible from an electrostatic loudspeaker; together with the imaging and sound-staging only possible from a theoretically ideal point source; and the coherence and continuity of a single drive unit. With possibly the lowest distortion of any loudspeaker, the ESL can be enjoyed for hours on end without fatigue; never adding or subtracting from the original recording. Even at low volume levels, they retain the full detail and drama of the music.
