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.

The Avant series incorporates an impressive battery of high tech features that take powered portable systems to a new level of performance. The latest in Class D power amplification, digital signal processing and optimized D.A.S. components have been combined with enclosures designed for ease of  transportation and road worthiness.

The Avant 12A offers a multi-angle enclosure which allows it to be used in stage monitor applications as well as a compact P.A. system.

The 600 W Class D amplifier provides extended bandwith, improved dynamic range and exceptionally low distortion. This makes the Avant series one of the best sounding systems on the market. After all, isn´t quality sound what it´s all about?

The 12AV4 loudspeaker designed and built by D.A.S. provides accurate low frequency reproduction. High frequencies are handled by the M-50N compression driver which uses a neodymium magnet structure and 2" titanium diaphragm-features hard to find on other systems in this market segment.
