Italian Stage S118A — 18" Active Subwoofer for Live Sound Reinforcement

The Italian Stage S118A is an 18" active subwoofer engineered to extend the low end of small and mid-sized PA systems. Built around a wooden cabinet and a Class AB amplifier, it delivers the kind of chest-level foundation that vocal-only tops struggle to reach on their own. Reliable low-frequency reinforcement is now accessible for mobile DJs, solo performers, and small venue operators who need performance without hauling a full touring rack.

Built for Punch and Headroom

What separates this sub from many entry-level units is the Class AB amplifier topology paired with a sizeable 18" driver. Cabinet construction consists of wood rather than plastic, which keeps resonance tight and predictable. A switchable AC110V/AC230V power supply makes it road-ready across European and overseas mains standards.

Driver and Amplification — Low-Frequency Output

The 18" woofer moves serious air, and the 350 W RMS amplifier gives it the headroom to stay composed on kick-heavy material. Peak power of 700 W covers transients without obvious strain.

• A large 18" radiating surface on the woofer allows for significantly deeper, more even bass production compared to 15" alternatives.
• RMS Power: 350 W — sustained output for continuous program material
• Peak Power: 700 W — headroom for kick and bass transients
• Amplifier Class: Class AB — proven topology for musical, controlled low end

Frequency Response and SPL — How Loud and How Low

The frequency range reaches down to 20 Hz and tops out at 120 Hz, which is the standard handoff point for full-range tops. Peak SPL of 129 dB is enough for small clubs, houses of worship, and conference rooms.

• Frequency Range: 20 Hz–120 Hz — full sub-bass coverage with a clean crossover point
• Peak SPL: 129 dB — comfortable headroom for typical live program material

Connectivity and Control Panel — System Integration

The rear panel is laid out for fast setup. Two XLR inputs feed two XLR outputs, so signal can be daisy-chained to tops without a separate splitter. Using the 100 Hz high-pass filter on the outputs cleans up the tops, while the phase switch and ground lift solve common wiring headaches on stage.

• Inputs: XLR — balanced line-level connection from mixer or source
• Outputs: 2× XLR — pass-through to satellite tops with high-pass engaged
• Controls: Phase switch, 100 Hz crossover, ground lift, volume — on-the-fly tuning without external processing
• EQ: No onboard EQ — relies on crossover and phase controls for shaping
