RMS Acoustics C12

OVERVIEW

The RMS-Acoustics C12 is a coaxial loudspeaker system 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.

The C12 features an advanced high frequency waveguide that also acts as a phasing plug for the 12” cone loudspeaker. The horn is quite large for its size, yielding consistent pattern control and a low crossover point. The phasing plug improves the response of the cone loudspeaker minimizing the equalization and phase correction needed, thus aiding the transition between sources over the crossover band.

The C12 features a 40° trapezoidal angle to allow close mountings to walls or ceilings, with little to no impact on sightlines. Its tailorable pattern control, easy mounting and array ability with RMS-Acoustics array brackets allow a simple, cost effective method to tailor a sound reinforcement solution to achieve the best possible acoustical results in almost any space.

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 C12 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.

The optimum processed amplifier solutions for the RMS-Acoustics C12 are the RMS-ACOUSTICS series of processed and network managed amplifiers, also the Linea Research C and M series amplifiers, with proprietary presets provided by RMS-ACOUSTICS
