It delivers a frequency response of 30 Hz to 100 Hz with a maximum peak SPL of 139 dB half-space, positioning it as a high-output touring and installation subwoofer for demanding live sound applications.\u003c\/p\u003e\n\u003cp\u003eThe onboard DSP provides 6 presets covering four distinct voicings (Original, Deep, Punch, Infra) and two cardioid configuration presets for use in multi-subwoofer arrays. A 6-step digital delay and 0\/180-degree phase switch enable precise time and polarity alignment with full-range tops. Two M20 top-mount sockets support satellite speakers above the cabinet; powerCON TRUE1 duplex connectivity allows daisy-chaining of AC power between units. The 18 mm Baltic birch plywood enclosure is fitted with four aluminium handles and provision for optional rear-mounted wheels.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e18\" woofer with 4\" voice coil:\u003c\/strong\u003e high-excursion driver engineered for extended low-frequency output and controlled excursion at high power levels, covering 30 Hz to 100 Hz at -6 dB.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e1200W RMS Class D amplifier:\u003c\/strong\u003e FBT-designed amplifier with switch-mode power supply delivering 2400W peak output with high efficiency and low thermal load at sustained high SPL levels.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e6 DSP presets with detailed voicings:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eOriginal:\u003c\/strong\u003e general-purpose preset, LPF at 95 Hz, balanced SPL and distortion.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDeep:\u003c\/strong\u003e extends low-frequency response to approximately 40 Hz, LPF at 95 Hz, fast peak limiter for minimum distortion;
