RCF NX 915-A

RCF NX 9: a series designed for stage, touring, and intensive use

The NX 915-A is part of the NX 9 Series, a range designed to offer a very "on-the-ground" balance between power, definition, and reliability. The goal is clear: to provide a speaker capable of delivering a high acoustic pressure level while maintaining intelligible listening, with consistent directivity and controlled response across the entire spectrum. With its all-wood enclosure, the NX 915-A targets regular use, transport, and installation without compromising robustness.

A speaker tailored for musicians, bands, and DJs

Whether you are a solo musician, in a band, or a DJ, the NX 915-A is designed to become a reliable main solution: it projects, handles high levels, and remains intelligible as the mix thickens. The 15-inch woofer provides the necessary foundation for vocals, keyboards, guitars, and DJ tracks, while the 1.75-inch compression driver ensures clear presence in the high-frequency range. Thanks to its specified coverage of 100deg x 60deg, it helps maintain a homogeneous sound across the listening area, practical for front of house as well as side fill applications.

Its compact format and mounting options facilitate integration into a wide variety of setups: pole mounting, wall installation, placement on structures, or suspension via designated points. The result is an active speaker that adapts equally well to mobile performances and installations where discretion and efficiency are paramount.

Technologies and design: power, control, and consistent dispersion

Class D bi-amplification: dynamic headroom and efficiency

With two-channel Class D amplification totaling 2100 W, the NX 915-A is designed to maintain headroom. This power reserve helps preserve signal cleanliness and impact sensation, especially on transients (snare drum attack, bass slap, electronic kick) and vocals, which remain forward without becoming harsh.

Constant directivity waveguide: more even coverage

The dispersion relies on a constant directivity waveguide, specified for 100deg x 60deg coverage. Practically, this helps distribute sound energy more evenly, limiting pronounced variations between on-axis and off-axis listening. This is an advantage for venues where the audience is not perfectly centered, as well as for stage comfort when the speaker is used as reinforcement.

RCF DSP: FiRPHASE and Bass Motion Control

RCF integrates two DSP treatments dedicated to transducer behavior. FiRPHASE works on phase response to improve coherence and perceived precision, resulting in better definition and a more stable image. Bass Motion Control manages the excursion of the woofer to maintain deep bass while keeping control: useful when pushing the system and avoiding "muddy" or overwhelming bass.

Tour-ready wooden enclosure

The all-wood enclosure enhances overall durability and meets the demands of frequent transport. The NX 915-A is designed to be easy to carry and quick to deploy, with mounting options tailored to the needs of stage, event, and installation applications.
