ES-10 Product Description:
ES series adopts the world's high-end speaker unit and lightweight imported birch board, through computer design, accurate frequency division and broadening frequency response characteristics and good control coverage performance. At the same time, the rotatable compression horn allows it to be mounted vertically or balanced, and the smooth frequency response and precise crossover ensure that the listener has the best possible sound quality. Pure language sound is more ideal. High-end bars and slow-shake bars need to balance smooth and wide vocal ranges, and the over-the-top and muddy sound quality characteristics are not listenable. In particular, the sound system of slow shake bars and bars must provide smooth and powerful bass in order to reproduce these music, and the ES series has been designed by computer to focus the mid and high tweeters in the area where impact and high power are needed to extend the best vocal performance.
