This highly professional 2-way active system is designed for absolute, long-term reliability. With its rugged bass reflex housing and finely tuned, user-friendly presets, it is suitable for use as a full-range speaker, satellite or monitor. The STINGER® 28 A G3 is powered by a highly efficient Class-D amplifier with a powerful 500-watt continuous output. Its two specially developed 8″ woofers and a BMS tweeter driver achieve a powerful bass response and fresh, natural trebles. The wave guide of the tweeter has been developed using the Boundary Element Method (BEM), a numerical simulation of the sound radiation and dispersion. It reduces reflection from floors and ceilings and prevents sidelobe levels, thus achieving controlled and homogeneous dispersion. Situated directly in front of the two 8” woofers, phase plugs ensure that midrange efficiency is increased and harmonic distortion above the crossover frequency is reduced.

LD Systems’ proprietary DynX® DSP technology means that the STINGER® 28 A G3 delivers perfect performance with maximum clarity and power under all conditions. The signal processing of the crossover function and the multi-band limiter achieve an optimal runtime and high freedom from distortion. Designed as an all-around workhorse, the housing of the speaker is made of robust birch plywood. An extremely resilient coating of polyurea offers exceptional robustness and durability. The features include a steel front grille, a dual-tilt stand attachment, flight points and ergonomic handles. The STINGER® 28 A G3 is a good value and attractive solution for professional sound systems, with extensive accessories that support usage on the stage and in fixed installations.
