Nexo STM S118 Sub Module subbass cabinet features a Neodymium high excursion 3000W 18" driver.

Nexo STM S118 Sub Module

A bandpass load ensures SPL output equivalent to conventional dual 18" subbasses. Same width, double the height of M46 main cabinet, double height of main cabinet so the S118 can be flown in the array or ground-stacked in line. Can be run in omnidirectional or cardioid sub mode.
