STM M46 Main Module
Injection-moulded high-power cabinet with innovative components for enhanced performance. Flat-membrane drivers ensure completely even and full-range coverage over entire 90° horizontal dispersion. HF frequency range remains completely linear, using Ketone Polymer diaphragms that enhance tonal response and long throw.
M46 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.
