NEXO STM S118 18-inch Bandpass Sub Bass Module, Installation Version

The NEXO STM S118 is a high-output sub-bass module built around a single 18-inch high excursion Neodymium driver loaded in a bandpass enclosure, delivering output equivalent to a conventional dual 18-inch subwoofer. It is designed for use within NEXO STM-based sound reinforcement systems.

With a frequency response of 25 Hz to 85 Hz and a peak SPL of 143 dB, the STM S118 provides substantial low-frequency extension and headroom. Switchable omni or cardioid dispersion modes allow system designers to control rear rejection and reduce stage spill.

The cabinet is constructed from Baltic birch ply finished with a structured black coating and connects via 2x NLT4-MDV Speakon 4-pole in/out connectors for straightforward system wiring. The STM S118 is covered by a 2-year warranty.
