Nexo STM B112 Bass Module

Nexo STM B112 Bass Module's injection-moulded bass cabinet features a Neodymium high excursion 3000W 12" bass driver with 4" voice coil.

Nexo STM B112 Bass Module

It has the same format – dimensions, weight, gravity centre – as the M46. The hybrid horn-loaded design maximizes the efficiency of the driver, delivering 6dB more than a standard front-loaded driver in this frequency range.

Key Features

  • 1 x 3000W +/- 3cm excursion 12 inch LF Driver
  • 141dB peak SPL
  • Frequency response: 63Hz-200Hz
  • H350mm/W575mm/D715mm
  • 55Kg/121lb

System Operation
Electronic Controller The NEXO NXAMP4x4 presets are precisely matched to the STM Series cabinets and include sophisticated protection algorithms. Using STM Series cabinets without a properly connected NEXO NXAMP4x4 will result in poor sound quality and can damage components.
SubBass STM S118 extends system low frequency response down to 25Hz
Speaker Cabling 1-/1+: SUB - 2-/2+: LF

  • [a] Response curves & data : Half-Space Far Field for the STM S118 & B112 + NXAMP4x4.
  • [b] Sensitivity & Peak SPL data : these will depend on spectral distribution and crest factor of program material. Measured with band limited Pink Noise. Data are for speaker + amplified controller. Peak SPL is at clipping of NXAMP4x4.
  • [c] Directivity curves & data : obtained by computer treatment on off axis response curves.
