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 Installation (-I) variant, sharing the same width as the GEO M12 main cabinet for tidy, system-matched fixed installs. Its bandpass enclosure and quadratic profiled port deliver high output efficiency in a compact footprint.
