Sound Barrier iLX12DSUB — 12″ Active Subwoofer with Selectable Crossover
iLX12DSUB Overview
The Sound Barrier iLX12DSUB is a 12″ active subwoofer engineered for professional PA systems, mobile DJs, live performers, and installed audio environments. Powered by a high-efficiency Class-D amplifier, it delivers controlled bass response with strong transient accuracy across a wide range of sound reinforcement applications. Its rear-panel control suite includes a selectable crossover (80Hz, 100Hz, 120Hz, or 150Hz), a 0°/180° phase switch, a Full/HPF output selector, and a Ground Lift switch for practical, on-site system integration. The iLX12DSUB is designed for audio engineers, system integrators, and touring professionals who require reliable low-frequency reinforcement with meaningful system control.
The balanced enclosure design prioritizes both output capability and portability, making the iLX12DSUB a practical choice for applications where deployment flexibility and consistent bass performance are equally important.
Key Features
