STM M46 Main Module
The high-power loudspeaker enclosure is molded with advanced components to enhance performance. The flat diaphragm driver ensures completely even and full-range coverage across the entire 90° horizontal coverage angle. The high-frequency range is fully linear, utilizing a ketone polymer diaphragm to improve sound response and projection distance.

The M46 features the innovative PistonRig™ and REDLock™ suspension systems, allowing the system to be securely suspended by one person at any size. REDLock™ handles lock the front suspension points from the rear of the speaker enclosure. All adjustments are made from a single location at the rear of the speaker assembly.

STM M28 Multi-purpose Module

The versatile, injection-molded speaker enclosure acts as a downfill, providing a 90°/120° horizontal dispersion angle and a module tilt angle of 0° to 15°. With the same width as the M46 and two-thirds the height, the M28 can also operate independently of the M46 or B112 to form a compact line array system.

The M28 is equipped with the advanced CompassRig™ and REDLock™ suspension systems, allowing the system to be safely suspended at any scale by a single person.

CompassRig™ allows you to pre-set the tilt angles between the speaker enclosures.
The REDLock™ handle helps secure the front suspension points from the rear of the speaker enclosure.

All adjustments are made from a single location at the rear of the speaker assembly.
