• Drivers: 2 x 18" High-Power Woofers, each with a 4.0" voice coil. These transducers utilize a high-power ceramic magnetic circuit designed for low distortion and consistent performance.

• Frequency Response: 30 Hz  120 Hz, providing deep and accurate bass extension.

• Maximum SPL: Up to 137 dB (Sound Pressure Level) at 1 meter, ensuring massive low-end impact for large venues and demanding scenarios.

Processing & Control:

• DSP (Digital Signal Processing): Integrated sophisticated DSP provides precise control over the sound.

• Presets: 12 onboard presets allow for quick adjustments to match different room acoustics and performance needs.

• Crossover Frequencies: Selectable crossover frequencies to seamlessly integrate with full-range PA speakers.

• Controls: Rear panel controls include:

  • Crossover Frequency

  • Polarity Switch

  • Deep/Punch Selection (for shaping the bass response)

  • Cardioid Presets (4 presets for cardioid configurations to reduce unwanted bass spill to the rear of the subwoofer)

  • Output Delay Settings (for time alignment in complex PA setups)

• Protections: Thermal, Excursion, and RMS limiters to protect the drivers and amplifier.

• Limiter: Soft Limiter for controlled output at maximum levels.

Construction & Connectivity:
