M-C15

The M-C15 is the larger of two coaxial stage monitors from EM Acoustics – a compact two-way design intended to satisfy the most demanding artist. The M-C15, and the smaller companion M-C12 – are intended not only to be world-class stage monitors, but also to suit today’s rental market by being genuine multi-purpose loudspeakers.
  • Features allow use both as a stage monitor but also a powerful FOH or installation product
  • 60°H x 40°V constant directivity waveguide
  • Premium 15mm multi-laminate birch plywood enclosure
  • Impact and weather resistant black or white textured finish as standard
  • RAL colour and enhanced weather protection options
  • 35mm polemount (hidden inside handle) and four M8 threaded rigging points
  • Hex punched stainless steel grille backed with acoustically transparent fabric

The low profile enclosure contains a 15” (381mm) neodymium LF drive unit with a coaxial 1.3” (33mm) exit HF compression drive unit, linked via the internal passive crossover network. Both the LF and HF drive units share the same magnet assembly, reducing overall weight and enclosure profile – making the M-C15 very compact and sleek. The HF drive unit is coupled to a bespoke constant directivity waveguide, which produces a 40°H x 60°V dispersion pattern on stage.

The robust enclosure is constructed from premium multi-laminate Birch plywood and is finished in an impact and weather resistant textured polyurethane coating. The enclosure contains a pair of M8 threaded mounting points in each end for attaching the optional flying hardware, and a 35mm polemount is hidden discreetly inside one of the handles to allow stand mounting. When used in this way as a powerful front of house loudspeaker, the waveguide produces a 60°H x 40°V coverage pattern.

The M-C15 is finished in an impact and weather resistant black or white textured polyurethane finish as standard, though RAL colour matching and enhanced weather-protection options are available. The front of the loudspeaker is protected by a rigid 2mm stainless steel grille backed with acoustically transparent fabric and supported by steel braces for additional strength. Two flush handles and protective floor skids complete the hardware package, and a single NL4 connector is provided on each end within a sculpted recess for discreet cabling.

The M-C15 requires a single amplifier channel, and the use of external DSP is recommended for system protection with high pass filters and limiters – as such it is recommended to be used with EM Acoustics’ range of Advanced System Amplifiers. It is however possible to use other DSP-enabled amplifiers, or conventional amplifiers with external DSP. Suitable DSP settings are provided on the EM Acoustics website. The M-C15 requires a single amplifier channel capable of delivering 750-1000W RMS into an 8-ohm load.
