Description
The AudioCenter GT515A is the 15-inch model in the GT Active Series, combining AudioCenter’s BrainCore™ technology with a customized 15-inch low-frequency driver, 1-inch-exit high-frequency driver, Class-D amplification, and FIR-based DSP. It is designed for full-range professional reinforcement in touring, rental, event, meeting, worship, and fixed-installation systems.
The GT515A delivers 1,100 watts RMS and reaches a published maximum calculated output of 130 dB continuous and 136 dB peak. Its 40 Hz to 20 kHz response provides the deepest low-frequency extension in the GT full-range family, while MAIN, LF BOOST, and W/SUB presets adapt the cabinet for stand-alone use or integration with subwoofers.
A rotatable 90-by-60-degree coverage pattern, symmetrical 45-degree monitor angles, M8 suspension points, and a dual-position pole socket allow multiple deployment methods. The enclosure uses CNC-machined plywood, a durable polyurea coating, iron grille, fan cooling, and comprehensive protection.
