Engineered for rock-solid reliability day in, day out this active 2-way system is a truly professional performer. With its multi-purpose bass reflex construction and carefully contoured, user-friendly presets it is equally suitable for fullrange, satellite or floor monitor applications. The Stinger® 12 A G3 is powered by high efficiency Class D amplification with a mighty 500 watts RMS output. It drives a custom designed 12” woofer and BMS compression driver delivering extended low frequency response and smooth, crisp highs. The HF waveguide has been designed using BEM, the numerical modeling of sound radiation and propagation. It reduces floor and ceiling reflections, effectively eliminates side lobes and achieves a controlled uniform coverage pattern. The Stinger® 12 A G3 incorporates LD Systemsʼ proprietary DynX® DSP technology to ensure top-level performance with maximum clarity and punch at all times. Processing includes crossover and multiband limiter functions for accurate time alignment and pristine, distortion-free audio. Designed to be a real workhorse throughout, the enclosure is made of rigid birch ply and coated with ultra tough polyurea for extraordinary strength and durability. Sporting a steel front grille, Dual-Tilt pole receptacle, multiple suspension points and ergonomic handles the Stinger® 12 A G3 is an attractively priced choice for truly professional sound reinforcement. A large selection of accessories facilitate live and installed applications.
