d&b audiotechnik M4 Stage Monitor

The M4 is a high performance 2-way stage monitor which features an integrated 15” LF and 1.3” exit horn loaded HF coaxial driver designed using neodymium magnets.

The stage monitor delivers constant directivity dispersion of 50° x 70°, and when positioned upright, it can function as a PA loudspeaker with a 70° x 50° dispersion pattern.

The M4 driver assembly rotates in 45° increments, allowing dedicated installation applications.

The M4 is available with NL4 Connections or NLT4 F/M Connections.
