Sound Barrier MG412 — 12″ Active 1200W Two-Way Full-Range Loudspeaker with SBT TWS
MG412 Overview
The Sound Barrier MG412 is a self-powered, two-way full-range loudspeaker designed for small to medium-scale professional sound reinforcement, AV presentations, houses of worship, distributed systems, front fill/infill, and stage monitoring. At its core is a 12-inch low-frequency woofer paired with a high-power 1-inch exit HF driver, driven by a built-in Hybrid Class D-AB amplifier delivering 1200W of peak output power. A 90° x 60° dispersion pattern and a frequency response of 50Hz to 19kHz provide broad, consistent coverage across a wide range of venues and applications. The MG412 is well suited for touring engineers, system integrators, houses of worship, schools, and conference facilities requiring a compact, versatile powered cabinet.
Constructed from Birch plywood for rigidity and resonance control, the MG412 includes a 35mm pole socket, integrated flying and suspension points, and a monitor wedge cut, allowing deployment as a satellite speaker, flown installation cabinet, or floor monitor. A rear pocket handle simplifies transport between gigs and installations.
