STM B112 Bass Module

Injection-moulded bass cabinet featuring a Neodymium high excursion 3000W 12″ bass driver with 4″ voice coil. 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.

B112 features innovative PistonRigTM and REDLockTM rigging, enabling any size of system to be flown safely by one person. REDLockTM handle locks front rigging points from rear of cabinet. All adjustments made from one position at rear of cluster.
