ES-10 Product Drawing

ES-10 Product Description

The ES series adopts world-class speaker units and lightweight imported birch wood panels. Through computer design, it has precise frequency division and broadening frequency response characteristics, as well as good control coverage performance. The rotatable compression horn allows for both vertical and balanced installation, with smooth frequency response and precise division to ensure excellent sound quality for listeners. Simply using language sounds is more ideal. High end bars and slow bars require a balance between smooth and wide vocal ranges. Overly exaggerated and turbid sound quality characteristics are not durable. Especially for slow bars and bars, the sound system must provide smooth and strong bass to replay these music. The ES series uses computer design to set the mid to high frequencies in areas that require impact and high-power treble, expanding the best vocal performance.
