Description
The d&b M4 Stage Monitor is a high‑performance 2‑way loudspeaker. Almost universally accepted on any performer or artist rider, you’ll find the M4 on a huge number of stages – and the techs love them too.
The M4 uses an integrated 15‑inch 1D LF driver and a 1.3‑inch 1D exit horn‑loaded HF coaxial driver, both featuring neodymium magnets. Its constant‑directivity horn provides a 50° x 70° (h x v) dispersion pattern, delivering a precisely defined coverage area on stage. You can also operate the M4 in 2‑Way Active mode.
You can position the cabinet upright, allowing the M4 to function as a powerful PA loudspeaker. In this orientation, it provides a 70° x 50° dispersion suitable for a wide range of applications. For installation use, you can rotate the M4’s driver assembly in 45° increments to achieve the desired dispersion characteristics.
The M4 cabinet is built from marine plywood with integrated handles. It features an impact‑resistant paint finish, M10 threaded inserts, and a socket for loudspeaker stands. A rigid metal grille backed with acoustically transparent foam protects the front of the cabinet. Two recessed runners on the bottom panel protect the enclosure from scratches and prevent movement. Full M4 specifications are available on the d&b audiotechnik website.
