dB Technologies ES503

dB Technologies ES503 – Portable 1000W 3-way PA system with flexible mono/stereo configuration
The dB Technologies ES503 is a powerful, portable, and versatile sound system designed for musicians, DJs, speakers, and event venues where high sound quality and flexibility are essential. The system consists of two lightweight and portable satellites (4 × 3” full-range) and a 12” active subwoofer that together deliver up to 121 dB SPL. Its compact size and modern design make the ES503 one of the most versatile portable solutions in its class.

The subwoofer is equipped with a 1000 W Peak DIGIPRO G3® Class-D amplifier and features a built-in 3-channel mixer with a Bluetooth® receiver. The top units’ Logarithmic Curved Column Array technology ensures both wide horizontal dispersion and asymmetrical vertical coverage, providing clear voice reproduction and even sound distribution—whether the audience is seated or standing.

The ES503 can be used in three different configurations (Mono, Stereo, and Double Column Mode), making the system adaptable for everything from small meetings to larger live performances. In Double Column mode, two ES503 systems can be linked together, with one acting as the master via the balanced output and controlling the entire setup via its OLED display.
