NEXO STM S118 18-inch Bandpass Subwoofer, Touring Version, Black

The NEXO STM S118 is a touring sub-bass module built around a single 18-inch (46cm) high excursion Neodymium driver rated at 3,000 W. Its bandpass-loaded cabinet is designed to match the SPL output of a conventional dual 18-inch sub-bass enclosure, making it a compact option for live sound reinforcement and touring applications.

The module delivers a frequency response of 25 Hz – 85 Hz ±3dB (27 Hz – 85 Hz ±3dB when used with NXAMP 4x4 amplification), a sensitivity of 109 dB and a maximum peak SPL of 143 dB. Omni or cardioid operating modes allow the array configuration to be tailored to the venue, while the 16 Ω (12 Ω minimum) nominal impedance supports flexible amplifier pairing.

Connectivity is handled via 2x NLT4-MDV Speakon 4-pole connectors for input and output looping, simplifying cabling in multi-cabinet arrays. The cabinet is constructed from Baltic birch ply finished with a structured black coating, and the STM S118 is covered by a 2-year warranty.
