Overview
STM M28 Omni-Purpose Module Install Version Custom Paint
Injection-moulded all-purpose loudspeaker cabinet which fulfils the role of downfill, providing 90°/120° of horizontal dispersion and 0° to 15° splaying angle between modules. Same width as M46, 2/3 height, the M28 can also be used independently from M46 or B112 to create compact line array systems.
M28 features innovative CompassRigTM and REDLockTM rigging, enabling any size of system to be flown safely by one person. Compass RigTM allows pre-setting of inter-cabinet angle values. REDLockTM handle locks front rigging points from rear of cabinet. All adjustments made from one position at rear of cluster.
