  • ES503 is a portable 3-amped stereo sound system composed by two passive tops and one 12” subwoofer. The sub hosts a 1000W peak power amp module with auto-range PSU and a 3-channels mixer with Bluetooth connection. A powerful DSP - controlled through an advanced user-interface with an OLED display - manages both the coverage of the entire system and all functions of the mixer, making the ES503 a real gem in terms of sound performance and versatility. The ES Series is the result of experience gained from dBTechnologies in the acoustic design of vertical array systems like DVA T Series and MINI. The components of the top are aligned mechanically (Logarithmic Curved Column Array) so as to increase the coverage of the vertical beam. Furthermore, there is a special “double-ringed phase plug” that increases the horizontal coverage and gives a rich and crystal clear sound to the system. The bass-reflex subwoofer houses a generous 12” woofer and the amplifier module. In addition to the input connectors and controls of the user-interface, there are two Speakon outputs and a VDE Mains connector. The enclosure, sturdy and stylish, is made of plywood coated with a durable scratch-resistant black coat, which makes it truly road-ready. Two recessed handles (one per side) help easy transport. Finally the metal grid with foam, in addition to protecting the woofer and give a very elegant and professional look, helps the reflex effect. The lower part of the grid, placed right on the reflex ports, have in fact holes with a larger diameter to enhance air flow.
