Constructed from Baltic birch play, the MSUB 12 sub bass module measures 396mm wide (15.6″) x 433mm high (17″) x 550mm deep (21.7″) and weighs 23kg (51lbs). It employs a single 12″, 6 Ohm, long excursion Neodymium driver in a high-efficiency, band pass cabinet design with a quadratic shaped profiled port.

Slightly wider than the GEO M6 main and bass modules, rigging hardware makes it easy to deploy the MSUB 12 in ground stacks and line arrays of various scales. Amplification and processing are via NEXO’s NXAMP4x1MK2, with a single channel required for each sub.

With a nominal peak SPL of 130dB, the MSUB 12 has available crossover frequencies of 45-85, 45-120, 45-150, 63-120 and 63- 150Hz, extending LF response down to 45Hz.
