Professional-grade monitor technology once reserved for high-end rental markets is now accessible to all performers with the MON 12 A G3 powered stage monitor. This cutting-edge unit represents a complete reimagining of stage monitoring, incorporating advanced coaxial loudspeakers with integrated 50° x 90° CD horn technology that creates a true point source for exceptional audio characteristics, even at close listening distances.
The 12"/1" configuration has long been recognised as the sweet spot for balancing sonority, sound pressure and portability in stage monitors. The MON 12 A G3 modernises this proven concept through coaxial design and intelligent electronics, wrapped in LD Systems’ signature professional aesthetic. Its versatile dispersion geometry can be configured as 50° x 90° for monitor applications or 90° x 50° for front-of-house use, making it a genuine multi-purpose solution.
Built for demanding professional environments, the MON G3 Series combines robust construction with comprehensive functionality. Both signal connections (XLR/jack combo) and power (PowerCON compatible) feature loop-through capability, enabling clean, efficient cabling in multi-monitor setups and distributed sound reinforcement applications. This thoughtful design approach ensures the MON 12 A G3 meets the practical demands of modern live sound while maintaining the premium materials and advanced technology found in top-tier monitoring systems.
