Advanced stage monitor ideal for loud band stages or as a front PA.

The LD Systems MON 15 A G3 stage monitor incorporates the advanced technology and premium materials found in high-end monitors typically rented by professionals and makes it available to everyone. This includes advanced coaxial loudspeakers with integrated 50° x 90° CD horn, which ensure the acoustic ideal of a true point source and thus outstanding audio characteristics even at short listening distances. The monitor also offers a high-level of robustness, a comprehensive set of features and the elegant LD Systems design.

A maximum sound pressure level of 129dB and superior bass reproduction make the MON 15 A G3 the best choice for loud band stages, as a drum fill or for stand-alone use as a compact front PA without an additional subwoofer. For a 15" stage monitor, it is unusually compact and elegant, so despite its impressive performance data, it blends harmoniously into the stage set. Both the signal (XLR/jack combo) and the power connection (powerCON compatible) can be looped through. This allows for elegant, tidy cabling in multi-monitor setups or for distributed sound reinforcement.
