A Technology-laden, Powered Stage Monitor

The LD Systems MON 15 A G3 is a compact, powered stage monitor with a high-performance design. Armed with a 1,200-watt Class D power amp, the MON 15 A G3 boasts a 129dB maximum SPL. Its 15-inch woofer and 1-inch titanium-diaphragm coaxial tweeter yield a 48Hz–20kHz frequency response along with a stage-filling 50-degree x 90-degree dispersion pattern. Its second-generation DynX DSP ensures distortion-free sound, even with the volume cranked, and you get a 3-band EQ, notch filter, four application presets, and a delay line function. You'll appreciate the MON 15 A G3's rugged PowerCON-compatible loop-through power connection, while its 35mm speaker stand flange makes it ideal for FOH applications. An ultra-durable polyurea coating and heavy-duty front grille round out the MON 15 A G3's robust features.

Inventive coaxial design

The MON 15 A G3 brandishes a clever coaxial design, which yields a rock-solid, true-point source via its 1-inch titanium-diaphragm tweeter and its 15-inch woofer with a 3-inch voice coil. This active stage monitor's BEM-optimized horn exhibits a 50-degree x 90-degree dispersion pattern. You also get a bass reflex port, which gives you thunderous low-frequency response all the way down to 48Hz.

State-of-the-art DynX DSP

Thanks to the LD Systems MON 15 A G3's proprietary second-generation DynX DSP, you can expect dynamic, high-resolution sound across the entire frequency spectrum, along with distortion-free performance — even at maximum volume. The MON 15 A G3 also includes four intuitive sound presets and a 3-band EQ for fast, user-friendly sound adjustment. When we ran the MON 15 A G3 through its paces here at Sweetwater, we were especially impressed by the effective feedback elimination afforded by its tunable notch filter. You also get a delay line function, compensating for distances up to 33 feet.

High-efficiency Class D power

The MON 15 A G3's highly efficient Class D power amplifier delivers 300 watts RMS and 1,200 watts peak with a dynamic, assertive, stage-filling sound. A secure, PowerCON-compatible port ensures a reliable power connection for your performance, allowing the daisy-chaining of multiple MON 15 A G3 units for efficient power management onstage. You also get two XLR/Jack Combo input channels for parallel connection of multiple audio devices and a pass-through connector that allows direct signal transmission to other devices or monitors, maintaining uniform sound across your entire system.
