    ES503 is a 1000W Power Amp Peak sound system composed by 2 slave 4x 3” full-range tops and 1 master 12” subwoofer. dBTechnologies’s 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:

  • 1 MONO MODE: The two satellites are connected top-on-top (thanks to a quick and easy slide connection system) and are placed on the subwoofer through a D25mm pole.
  • 2 STEREO MODE:Each satellite is placed on a tripod
  • 2b STEREO MODE: 1 Satellite on a pole, 1 on a tripod
  • 3 DOUBLE COLUMN MODE: a ES503 system in mono mode becomes the master for a second ES503 feeding the signal thanks to the integrated balanced output channel. This way, both system are driven by the master’s on board mixer and any setup is guided through the master’s OLED display.
  • The ES503 is equipped with a three-channel mixer, and a built-in Bluetooth™ stereo module, which receives audio from devices such as mobile phones, tablets or any other audio device.

    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.
