RCF NX 945-A

An NX Designed for the Stage: RCF DNA Serving Compact Power

Designed with a "road-ready" spirit, the RCF NX 945-A is part of the NX series as a high-end active sound reinforcement solution, focused on performance efficiency and reliability under heavy use. Its all-wood enclosure, lightweight architecture with neodymium magnets, and modern electronics aim for a clear goal: to offer a 15-inch powered speaker capable of delivering a solid front-of-house presence without complicating setup.

Whether in a mobile configuration or installation, it stands out with a particularly interesting power-to-size ratio: reserve for transients, controlled projection, and a sonic signature designed to remain intelligible in demanding environments.

An Active Speaker for Front-of-House, Satellite, or Monitor: Who Is the NX 945-A For?

The NX 945-A is aimed at sound engineers, DJs, bands, and service providers seeking an active speaker capable of covering a bar, club, local stage, or corporate event with quick setup. As a standalone front-of-house speaker, it delivers already generous bass and well-present midrange; paired with a subwoofer, it becomes a formidable satellite in power and definition.

Its controlled directivity favors vocal intelligibility and instrument precision while limiting unwanted dispersion toward walls or ceiling. It is also suitable for use as a stage monitor when you need a powerful, clear wedge capable of handling sustained levels without becoming harsh.

RCF Technologies: Projection, Temporal Precision, and Controlled Bass

True Resistive Waveguide: a wide sweet spot, a mix that "holds" in the room

The True Resistive Waveguide is designed to maintain consistent dispersion so that the mix perception remains coherent regardless of listening position. With a coverage of 100 x 70, the NX 945-A helps better "fill" the space, reduce overly loud or weak zones, and secure vocal clarity in reverberant environments.

Neodymium Transducers: speed, impact, and definition

The combination of a 4-inch compression driver (titanium dome) and 15-inch woofer (neodymium magnet) aims for a dynamic and detailed sound. Snare attacks, vocal nuances, and bass lines maintain presence, with a low-midrange that "carries" without unnecessary boominess. The result: a speaker that naturally cuts through the mix while maintaining comfortable listening over time.

FiRPHASE DSP and Bass Motion Control: clarity at high levels, clean bass

The FiRPHASE processing works on temporal alignment to provide a more precise response, with better-defined transients and a clearer sound image. Meanwhile, Bass Motion Control manages woofer excursion to preserve low-end depth while limiting undesirable behavior when the speaker is pushed. You gain stability, articulation, and cleanliness even as volume rises.

2100 W Class D: headroom for peaks without losing control

Thanks to its Class D bi-amplification delivering 2100 W, the NX 945-A offers appreciable headroom for peaks (vocals, kicks, synths, impacts). This reserve results in a more relaxed sound, less perceived compression at high volume, and better overall mix integrity, especially in setups where a pair of speakers must deliver a large share of the event's energy.
