NEXO STM S118 18-inch Bandpass Subwoofer, Touring Version

The NEXO STM S118 is a bandpass sub-bass module designed for touring and live sound reinforcement, extending the low-frequency output of the STM line array system.

Powered by a single 18-inch (46 cm) high excursion Neodymium driver rated at 3,000 W, the cabinet delivers up to 143 dB peak SPL with a frequency response of 27 Hz – 85 Hz ±3 dB, matching the output of conventional dual 18-inch sub-bass cabinets. The module can be configured in omnidirectional or cardioid mode to suit different venue and coverage requirements.

Connectivity is provided via 2x NLT4-MDV Speakon 4-pole in/out connectors, and the cabinet shares the same width as the STM M46 main enclosure, allowing it to be flown within the array or ground-stacked in line. The enclosure is built from Baltic birch ply finished with a structured black coating, and the STM S118 is covered by a 2-year manufacturer warranty.
