The ES Series by dBTechnologies is a complete plug-and-play column system, equally multifunctional, portable, space-saving and user-friendly. The ES503 is a 1000W Power Amp Peak sound system composed by 2 slave 4 x 3” full-range tops and 1 master 12” subwoofer. dBTechnologies' components and design allow an amazing SPL/size ratio: 95x355x137 mm and 1.9 kg for the tops and 465x400x430mm 16.4 kg for the subwoofer for an overall 121 db SPL. The sub hosts a Digipro G3 amp module with auto-range PSU and a 3-channels mixer with Bluetooth connection. A powerful DSP manages all function of the on-board digital mixer, making the ES503 a real gem in terms of sound performance and versatility. The internal design of the tops allows an asymmetrical vertical coverage (thanks to the Logarithmic Curved Column Array technology) and a unique “double ringed” phase plug widens the horizontal coverage and guarantees a perfect voice intelligibility. This allows ES503 to adapt to any situation, both with a seated or standing audience. ES503 is the most eclectic among portable systems, allowing 3 different configurations suitable for hundreds of different occasions. The bass-reflex subwoofer houses a 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 power connector. The enclosure, sturdy and stylish, is made of birch plywood coated with a durable scratch-resistant black coat, which makes it truly road-ready. Two handles (one per side) help easy transport.
