It is powered by a 700W RMS Class D amplifier with a switch-mode power supply, engineered and manufactured in Italy by FBT, and operates across a frequency range of 40 Hz to 140 Hz with a maximum SPL of 133 dB peak.\u003c\/p\u003e\n\u003cp\u003eAn onboard DSP provides 8 presets covering standard and DJ voicings at two LPF crossover frequencies (90 Hz and 140 Hz), including four cardioid configuration presets for use in arrays where rear dispersion needs to be minimised. The stereo XLR input allows a single subwoofer to receive both left and right signals from the source, with a separate XLR link output for connecting satellite speakers. An 8-step delay adjustment (0 to 6 m) and a 0\/180-degree phase reversal switch enable precise system alignment with full-range tops. The M20 top-mount socket supports mounting a satellite speaker directly above the subwoofer.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e700W RMS Class D amplifier:\u003c\/strong\u003e FBT-engineered amplifier with switch-mode power supply, delivering 1400W peak output with high efficiency and minimal thermal load.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e8 DSP presets:\u003c\/strong\u003e four standard and four cardioid configuration presets, each available at 90 Hz or 140 Hz LPF crossover frequency, covering Original and DJ voicings.
