M4 High-Power Monitor
The M4 is a 2-way high performance stage monitor that produces 134 / 138 / 138dB SPL when driven passively with the D6 / D12 / D80 respectivly or 140dB SPL when driven actively with the D12 / D80. The constant directivity dispersion of 50° x 70° (h x v) delivers an accurately defined coverage area on stage and, when used upright, it is transformed into a powerful PA system with a dispersion suitable for a variety of applications.
The M4 cabinet is constructed from marine plywood, which incorporates the handles, and has an impact resistant paint finish. It has two M10 threaded inserts on each side panel to enable quick and flexible rigging and a socket to accept loudspeaker stands. Two runners recessed in the bottom panel protect the cabinet from scratching and prevent movement.
