LD Systems MON 12 A G3 12" Full Range Powered Coaxial Stage Monitor
The LD Systems MON 12 A G3 isn't just a stage monitor; it's a professional-grade powerhouse engineered for flawless performances. This compact yet robust unit packs advanced technology usually reserved for massive, high-end rental setups. All this sophisticated sound engineering is contained within a portable design, ready to elevate your audio to breathtaking new heights.
Crystal-Clear Sound Without Compromise
Enjoy crystal-clear vocals that cut through the mix, precise instrument detail, and reliable performance without feedback issues. The MON 12 A G3 turns the challenges of live sound into a seamless, balanced audio experience, letting you focus on delivering your best.
Coaxial Design Creates Audio Magic: The innovative coaxial loudspeaker configuration with integrated CD horn delivers true point source sound. Translation? Every frequency reaches your ears at precisely the same time, creating that sweet spot of clarity that makes mixing feel effortless instead of exhausting.
Class-D Amplifier Brings the Thunder: With 300W RMS pushing up to 1200W peak power, this monitor doesn't just play loud — it plays clean and controlled at stadium-shaking volumes. You'll hit that magical 127 dB max SPL without breaking a sweat (or your eardrums).
Smart Dispersion Pattern: The 50° x 90° radiation pattern is perfectly optimized for monitor use, ensuring every band member gets consistent coverage. Flip it to 90° x 50° and it doubles as a front-of-house speaker — talk about versatility that pays for itself.
Performance That Keeps You Moving
When the spotlight hits and the crowd roars, the last thing you need is gear that fights against you. The MON 12 A G3 becomes your silent partner, delivering consistent, distortion-free sound that keeps you focused on what matters most — your performance.
DynX® DSP Technology Eliminates the Ouch Factor: This second-generation digital signal processing ensures your monitor stays sweet and clean, even when you're pushing it to the absolute limit. No more wincing at harsh frequencies or muddy low-end — just pure, professional sound.
Flexible EQ and Processing Options: The 3-band EQ, notch filter, and four application presets give you the tools to dial in your perfect sound. Whether you're monitoring vocals, instruments, or full mixes, there's a preset that gets you 90% of the way there before you even touch a knob.
Through Connectivity Simplifies Setup: Both signal (XLR/jack combo) and power (PowerCON compatible) connections loop through seamlessly. This means cleaner cable runs, faster setup times, and fewer chances for that one cable to mysteriously disappear right before showtime.
Tough Build, Sleek Design
The MON 12 A G3 doesn't just sound professional — it looks the part too. This monitor is built to survive the rigors of touring while maintaining that sleek, sophisticated appearance that says "we know what we're doing" to every venue owner and sound engineer.
Polyurea Coating: The Road Warrior's Armor: This monitor wears a suit of armor — a tough Polyurea coating that laughs off dings, scratches, and even those rogue coffee spills. It keeps your monitor looking pristine, gig after glorious gig, year after year.
Heavy-Duty Grille: Driver's Valiant Shield: More than just a pretty face, that robust front grille stands guard. It's engineered to protect your precision drivers from the perils of the stage: flying drumsticks, enthusiastic dancers, and all the delightful chaos of live music.
Versatile Mounting: Pole Position for Your Power: With its 35mm speaker stand flange, this monitor isn't just for the stage floor. Pole-mount it for front-of-house action, giving you the ultimate flexibility to conquer any venue, any setup, any time.
Your Sound Reinforcement Game-Changer
The LD Systems Mon 12 A G3 combines professional performance, reliable durability, and affordable pricing. Designed for both seasoned touring musicians and weekend performers, this monitor offers the clarity and power needed to elevate any performance.
