The S503 is a tri-amplified stereo sound system composed of two passive tops and a 12 "subwoofer. The Sub hosts the 1000W amplification module with auto-range and a mixer 3-channel with Bluetooth connection. A powerful DSP, controlled by an advanced user interface e an OLED display, manages the dispersion of the system and all mixer functions, making the ES503 a real jewel in terms of audio performance and versatility. The ES series is the result of the experience gained by dBTechnologies in acoustic design of vertical array systems such as DVA T and DVA MINI series. The top transducers are aligned mechanically (columnar arrays with logarithmic curvature) in so as to increase the coverage of the vertical beam. Moreover, there is a special "double ring rephaser" that increases the horizontal coverage and gives a clear, rich sound and crystal clear to the system.
