ES503 – 1000W Peak Power Amplifier Sound System
The ES503 is a 1000W peak power system consisting of two slave 4 × 3" full-range top speakers and one master 12" subwoofer. Thanks to dBTechnologies’ high-quality components and design, it offers an outstanding SPL-to-size ratio: the top speakers measure 95 × 355 × 137 mm and weigh 1.9 kg each, while the subwoofer measures 465 × 400 × 430 mm and weighs 16.4 kg, delivering a total SPL of 121 dB.
The subwoofer is equipped with a Digipro G3® amplifier module with auto-range power supply and a 3-channel mixer with Bluetooth connectivity. A powerful DSP manages all functions of the built-in digital mixer, making the ES503 a true gem in terms of sound quality and versatility. The internal design of the top speakers allows for asymmetric vertical coverage (thanks to Logarithmic Curved Column Array technology), and a unique "double-ring" phase plug expands horizontal coverage and ensures perfect speech intelligibility. This enables the ES503 to adapt to any situation, whether the audience is seated or standing.
The ES503 is one of the most versatile portable systems, offering three different configurations suitable for hundreds of different applications:
-
MONO MODE: The two top speakers are stacked (using a quick and easy sliding connection system) and mounted on the subwoofer via a D25mm pole.
-
STEREO MODE: Each satellite is mounted on a separate speaker stand.
2b. STEREO MODE: One satellite on a pole, one on a stand. -
DOUBLE COLUMN MODE: One ES503 system in mono mode acts as the master for a second ES503 system, sending the signal via the integrated balanced output channel. Both systems are then controlled through the master’s built-in mixer, with all settings accessible via the master’s OLED display.
The ES503 features a 3-channel mixer and a built-in Bluetooth™ stereo module, allowing audio streaming from devices such as smartphones, tablets, or other audio sources.
The bass reflex subwoofer houses the 12" woofer and amplifier module. In addition to input jacks and user interface controls, there are two Speakon outputs and a VDE power connector. The robust, stylish cabinet is made of birch plywood coated with a durable, scratch-resistant black finish, making it truly road-ready. Two handles (one on each side) provide easy transport.
