The NEXO MSUB18 is an 18″ bandpass subwoofer that extends the low-frequency reach of NEXO’s GEO M series line arrays. This is the touring variant, sharing the same width as the GEO M12 main cabinet for system-matched stacks and flown builds. Its bandpass enclosure with quadratic profiled port delivers high output efficiency in a compact, road-ready footprint.
