Power that Moves

• The most powerful amplifier in its class. RCF's improvements in transducer design make them strong and powerful, so the amplifier follows the evolution. With 2100W power, the 2-channel NX 945-A Class-D amplifier is 50% more powerful than previous models, able to manage extreme sound pressure levels with an ultrafast attack, realistic transient response, and very low heat loss.
• The NX 945-A is energy-efficient, so there's no need for a cooling fan�the amplifier is attached to a solid aluminum heat exchanger in the rear of the cabinet�with no moving parts. The input circuit features a new low-distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. All NX 9 series amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high-efficiency with minimum weight.

Legendary Transducers

Potent woofer

• The low-frequency transducer is a high-power 15" woofer with a 3.5�� voice coil that delivers tight, punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent, and free from distortion.

Superior compression drivers

• The ND840 Compression Driver in pure Titanium with a 4" voice coil allows a crossover point at only 650 Hz. This allows a better impulse response, fast decay, and superior efficiency. Lightweight and powerful, RCF neodymium drivers are a reference in performance and reliability.

Direct Drive Technology

• The voice coil features a high-temperature Kapton former. The assembly process takes advantage of RCF proprietary Direct Drive technology. The diaphragm�s suspension has been designed following extensive research and development aimed at minimizing distortion and extending low-frequency range.

Bass Motion Control

• When searching for extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature.
• NX 9 Series with BMC can handle the lowest audible frequencies without affecting the woofer stability, providing extended linearity and better sound integrity.
• The BMC method works by creating a complete map of the dynamic behavior of the woofer to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the BMC algorithm breaks this rule.
• In combination with FiRPHASE technology, NX 9 has a new level of audio performance in this series of speakers.

FiRPHASE

RCF speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener.The special FiRPHASE filters allow for coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system.

Tour-Proven Workhorse

NX 9 can operate as either the main system or as a floor monitor. This flexibility makes it a smart choice for a wide range of live sound applications. The rugged all-wood cabinet is easy to carry with handles on both sides. The lower side includes a steel pole socket for mounting on a stand or a subwoofer pole. Each model can also be flown, wall- or truss-mounted using the six included M10 rigging points, Quick Lock pins, and special accessories. From the wood cabinet to the final texture and protective grille, NX 9 Series offers maximum strength for intensive use on the road and can be used for fixed installation.

Ready for Heavy-Duty Applications

The highly innovative entertainment industry is always evolving by increasing demands on interconnection systems. Particular environmentally sealed connectors are highly requested for heavy-duty and harsh environment applications of entertainment equipment. The speaker features True Outdoor Protection (TOP) PowerCON TRUE1 power input connectors. These ruggedized sealed connectors feature IP protection and UV resistance approved according to UL50E.
