The RCF NX945-A is designed for venues, bands, and DJs who demand high-quality audio. This powerful speaker combines a 4" titanium compression driver, a 15" neodymium woofer, and a 2,100W amplifier to produce up to 135 dB SPL of crystal-clear sound.
Versatile and adaptable, the NX945-A functions perfectly as a front-of-house speaker, a stage monitor, or a flown speaker. RCF's proprietary FiRPHASE and Bass Motion Control DSP processing work in tandem to deliver exceptional clarity and deep, powerful bass, ensuring a premium listening experience for your audience.
A Speaker That Means Business
When RCF says "power that moves," they're not kidding around. This beast packs more punch than a heavyweight boxer with a music degree.
2,100W Class-D Bi-Amplification: The NX 9 amplifier is 50% more powerful than its predecessors, delivering extreme sound pressure levels with lightning-fast attack and realistic transient response. Think of it as the Ferrari of amplifiers — fast, powerful, and efficient.
Fanless Design for Silent Operation: Thanks to the solid aluminum heat exchanger, this amplifier runs cool and quiet without any moving parts. No annoying fan noise competing with your carefully crafted mix.
Advanced Safety Limiter: The input circuit features a low-distortion design with an intelligent safety limiter that preserves the true character of your signal at all levels. It's like having a bodyguard for your audio that never takes a day off.
Legendary Transducers That Deliver the Goods
The heart and soul of any great speaker lies in its transducers, and the NX945-A sports components that would make other speakers green with envy.
15" Neodymium Woofer with 3.5" Voice Coil: This powerhouse delivers tight, punchy bass that's accurate, transparent, and distortion-free. Your low-end will hit so clean, even your grandmother will feel the groove.
4" Titanium Compression Driver (ND940): With a crossover point at just 650 Hz, this driver provides better impulse response, lightning-fast decay, and superior efficiency. Titanium isn't just for wedding rings — it's for serious audio reproduction.
Direct Drive Technology: The high-temperature Kapton voice coil former and precision-engineered diaphragm suspension minimize distortion while extending the low-frequency range.
Bass Motion Control: The Game Changer
RCF engineers threw out the rulebook when they developed Bass Motion Control (BMC), and we're all better for it.
Intelligent Woofer Management: Instead of using traditional high-pass filters that mess with phase behavior, BMC creates a complete map of the woofer's dynamic behavior. It's like having a GPS system for your bass frequencies.
Extended Low-Frequency Response: BMC handles the lowest audible frequencies without compromising woofer stability, giving you extended linearity and better sound integrity. Your bass will go deeper than a philosophical conversation at 3 AM.
Perfect Partnership with FiRPHASE: Combined with RCF's zero-degree phase technology, the NX945-A achieves a new level of audio performance that'll make other speakers weep with jealousy.
Pure Audio Perfection
The RCF NX945-A 2100 Watt 15" 2-Way Powered Loudspeaker isn't just another box with drivers — it's a precision-engineered audio solution that delivers professional results every time. Whether you're powering a corporate event, rocking a festival stage, or providing pristine monitoring for recording artists, this speaker rises to the occasion with the reliability and performance that separates the pros from the wannabes.
