LD Systems MON 15 A G3 Powered Coaxial Stage Monitor PA Speaker (1x15")

With a coaxial design for phase-aligned sound even at short distances, the MON 15 A G3 stage monitor delivers enough low end for bass players and drummers.

The LD Systems MON 15 A G3 is part of a family of powered stage monitors built for high performance. The MON G3 Series incorporates the advanced technology and premium materials found in high-end monitors typically rented by professionals, making this quality available to everyone. These include, for example, 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. Besides this, the series offers a high-level of robustness, a comprehensive set of features and the elegant LD Systems design.

A maximum sound pressure level of 129 dB 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 set-ups or for distributed sound reinforcement.

"Great quality - SEVERLY UNDERPOWERED - Very low value for the money"

Overall: 2 out of 5 stars
(see rating details)
Why the heck LD would put out the new G3 monitors with such underpowered amplifiers is beyond me! Tried a few out. Had to crank them ALL THE WAY UP to get half of the volume that a Mackie Thump or Turbosound TFX would put out. If they were $300 it would be ok, but at this price you could buy a Thump215 for $450, save money, and have FOUR TIMES the power!Really LD?
