The M-12 is the reference stage monitor from EM Acoustics – a compact two-way design intended to satisfy the most demanding artist.  Whilst it is possible to run the M-12 as a bi-amplified unit, it is intended to be used in passive mode where it will outperform many bi-amplified or DSP-processed designs. The enclosure contains a 12” (305mm) LF drive unit, linked via the internal passive crossover network to a 3” (76mm) diaphragm, 1.4” (36mm) exit HF compression drive unit.  The HF drive unit is coupled to a variable dispersion waveguide, which produces a 90°H x 40°V dispersion pattern at one metre, narrowing to 50°H x 40°V at three metres.  This narrower dispersion at distance means a performer has freedom of movement at close range, whilst minimising spill into adjacent microphones at distance. The robust enclosure is constructed from premium multi-laminate Birch plywood and is finished in impact resistant textured paint.  The M-12 is supplied in black as standard, however RAL colour matching and weather protection options are also available if required.  The front of the loudspeaker is protected by a rigid steel grille backed with acoustically transparent foam.  Two steel bar handles and non-slip rubber feet complete the hardware package, and six NL4 connectors (2 each end, 2 on the front) allow for maximum cabling flexibility.  The M-12 is available as either left or right-handed variants for stage pairing. The M-12 requires a single amplifier channel in passive mode, and should be used with professional power amplifiers capable of delivering 750-1000W RMS into an 8-ohm load.  For best results, the EM Acoustics AQ-3 or AQ-10 power amplifiers should be used.
