Overview

The ‘fourth element’ in the suite of NEXO STM compatible loudspeaker modules, the STM-M28120 is an injection-moulded all-purpose 2- way loudspeaker cabinet, providing 120° of horizontal dispersion and 0° to 15° splaying angle between modules. M28 is the same width as the STM M46 main cabinet, 2/3 the height, and it can be arrayed in the same column with the M46 full-range speaker, the B112 bass cabinet (all sold separately) or used independently. Powered by the NEXO NXAMP Powered TDController, the M42 exhibits 140 dB SPL max output capability, superior horizontal control, and stable dispersion.
