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. 

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.
