SMX 12A LT
SMX 12A LT is a high‑quality active coaxial monitor engineered for long‑throw, wide‑coverage stage monitoring. With precise DSP presets, advanced limiter control, and a dual‑channel Class‑D platform, it delivers clear, dynamic sound for vocals, keys, drums, and more. A discreet, road‑ready enclosure with a hidden I/O panel keeps stages tidy, while flexible monitoring angles and daisy‑chaining make setup fast and predictable.
- Self-powered coaxial monitor with plug‑and‑play presets for fast, consistent sound
- Advanced limiter control for clean, dynamic performance at high levels
- Two monitoring angles to optimise coverage on deck, on subs, or in elevated positions
- Hidden I/O panel for clean stage aesthetics and protected connections
- Easy scalability via daisy‑chain for quick multi‑wedge deployments

Designed for professional live environments, SMX 12A LT combines a coaxial two‑way architecture with a carefully tuned crossover system to deliver focused imaging and consistent tonality across the performer’s position. The monitor responds musically to additional EQ, allowing engineers and artists to fine‑tune for taste without sacrificing clarity or headroom. Advanced limiter algorithms preserve transient punch and reduce pumping, maintaining articulate, distortion‑free performance even at elevated levels.
Practical flexibility is built in. Selectable DSP presets help tailor the monitor for general use or voice‑centric applications, providing a confident starting point that speeds soundcheck. Two dedicated monitoring angles let you optimise sightlines and coverage, whether the wedge sits on the deck, on a sub, or in elevated positions such as drum‑fills, while the coaxial design keeps phase response coherent and the sweet spot wide.
The cabinet pairs robust plywood construction with a durable external finish for life on the road. A hidden I/O panel keeps connectors and controls out of sight when placed on the floor, supporting clean stage visuals and safer cable runs. For larger stages or broader zones, multiple units can be daisy‑chained quickly, enabling scalable coverage without additional distribution hardware. Low processing noise and fast, plug‑and‑play operation ensure reliable day‑to‑day use so performers can focus on the show.
