OVERVIEW

The M15X is a 2-way high performance coaxial stage monitor designed to deliver output levels comparable to the highest output conventional premium 2-way systems, with superior pattern control, directional consistency, and a precise transient response that only a coaxial loudspeaker can provide. This advanced monitor employs an integrated 15” LF and 1.5” exit horn loaded HF coaxial driver design that utilizes a central neodymium magnet.

The precise 50 X 70 (h x v) constant directivity horn delivers and accurate, consistent coverage area, whether on stage, or when deployed for mains PA applications. The M15X horn features one of the proprietary RMS-Acoustics confocal elliptic waveguide shape, made with cutting edge additive manufacturing technology.

When used upright, or on a pole for mains PA applications, the horn will be in the 70 wide X 50 vertical, highly applicable to a wide variety of sound reinforcement applications.

Optimized nonlinear venting improves the low frequency impedance compared to conventional enclosures, while maintaining better mechanical cone control when low frequency extension is required. The result is tight, punchy bass that also goes deep.

The M15X enclosure is crafted from premium multi-ply birch with a finely textured polyurethane finish that is impact and UV resistant. A powder-coated, punched and laser cut steel grille protects the cabinet internal from the elements. Full weather protection and custom color finishes are also available. The weatherized option provides and IP54 rating. Rubber feet recessed in the bottom panel protect the cabinet from scratching and prevent movement on stage.

The optimum processed amplifier solution for the RMS-Acoustics M15X and Maximum performance can be achieved with the RMS-14K and RMS-10K power platforms. Amplifiers from Linea Research may also be used.
