This stage monitor employs an integrated 15”/1.3” exit coaxial driver design with neodymium magnet and constant directivity horn loading. Its dispersion of 50° x 70° (h x v) provides an accurately defined coverage area on stage. Used upright, it serves as a powerful front PA speaker (70° x 50°) for various applications.

The M4 is a two-way design with a built-in passive crossover network. It can optionally be operated in two-way active mode just by changing the configuration of the D12 amplifier without any modifications to the loudspeaker. Its frequency response extends from 55 Hz to above 17 kHz.

The monitor’s cabinet is marine plywood with an impact-resistant paint finish. Its front is protected by a rigid metal grill and replaceable, acoustically-transparent foam. The side panels incorporate a pair of handles, a pole mount socket and four M10 threaded inserts for connection to different rigging devices and brackets. Two runners recessed in the bottom panel protect the cabinet from scratching and prevents movement. Mounted on the rear panel are two EP5 or NL4 connectors wired in parallel.
