NEXO STM B112 12-inch Bass Module, Installation Version, Black

The NEXO STM B112 is a 12-inch bass module from the STM line array system, engineered for fixed installation applications where consistent low-frequency reinforcement is required. The Installation Version shares the same footprint, weight and gravity centre as the M46 cabinet, simplifying rigging in mixed STM/M46 systems.

The cabinet houses a single 3000 W high-excursion 12-inch Neodymium driver with a 4-inch voice coil, delivering a frequency response of 63 Hz–200 Hz ±3 dB, a sensitivity of 107 dB and a maximum peak SPL of 141 dB. Nominal impedance is 16 Ω (12 Ω minimum).

Connections are made via 2x NLT4-MDV Speakon 4-pole connectors (in/out), allowing straightforward daisy-chaining within an STM array. The enclosure is injection-moulded from low-density PU composite and finished in a water-based black coating for durability in permanent installations.

The STM B112 is covered by a 2-year warranty.
