Sound Barrier FM12CXA — 12″ Active Coaxial Stage Monitor with DSP
FM12CXA Overview
The Sound Barrier FM12CXA is a low-profile active coaxial stage monitor built specifically for live sound applications, delivering 2 x 700W (2800W peak) digital amplification through a 12″ neodymium coaxial transducer with a 3″ voice coil for high-output, high-intelligibility monitoring on demanding stages. Four onboard DSP presets, each modifiable via PC, allow engineers to tailor the speaker’s response to the specific demands of the application. With a maximum SPL of 128 dB, the FM12CXA maintains clarity and feedback rejection even at full power in the loudest venues. It is well suited for touring engineers, system integrators, houses of worship, and venue operators requiring a versatile, road-ready monitor solution.
The FM12CXA’s coaxial driver configuration provides a coherent point-source dispersion pattern that benefits both on-axis performers and off-axis coverage, while its Baltic Birch plywood cabinet with durable paint finish is built to withstand the rigors of extended touring and repeated deployment.
Key Features
- 2 x 700W Digital Amplification — Integrated Class-D amplifier delivers 2800W peak output, providing ample headroom for high-SPL monitoring environments
- 12″ Neodymium Coaxial Transducer — High-power woofer with 3″ voice coil and coaxially mounted HF driver for point-source coherence and consistent imaging across the stage
- 1″ Neodymium HF Driver — 3″ voice coil high-frequency driver mounted coaxially for time-aligned, phase-coherent reproduction
- 128 dB Maximum SPL — Delivers the output levels required for loud stage environments while maintaining intelligibility and feedback resistance
- 4 PC-Modifiable DSP Presets — Onboard DSP with four application-specific presets that can be customized via PC, enabling precise tuning for monitor, PA, or installation use cases
- Integrated Pole Mount Socket & Rigging Points — Supports deployment as a floor monitor, portable PA on a pole, or flown in permanent installation configurations
- Baltic Birch Plywood Cabinet — Finished with a highly durable paint coating, the enclosure is engineered for the structural demands of touring and repeated road use
- Low-Profile Monitor Design — Cabinet geometry optimized for stage monitoring, minimizing sightline obstruction while maintaining proper driver angle toward performers
