Description
NX985-A
Designed to deliver stellar audio performance and versatility for intensive audio applications, the RCF NX 985-A is a highly flexible, easy-to-use, 2100W powered PA speaker for today's working musicians, singer/songwriters, mobile DJs, and other sound providers. The speaker works in a variety of orientations and configurations for use as a main PA.
The highly efficient 2100W Class-D bi-amplifier delivers 1400W to the 15" woofer, 500W to the 8" midrange driver, and 200W to the 1.75" titanium/neodymium compression driver, which provide full-range audio (40 Hz to 20 kHz) with a sound pressure level powerful enough to ensure the entire audience can hear your performance. The NX 928-A utilizes RCF's proprietary FiRPHASE and Bass Motion Control DSP processing to deliver absolute clarity and deep, powerful bass response. The tour-ready, rugged all-wood cabinet is easy to carry and secure to install on a pole-, flown-, wall-, or truss-mounted using the dedicated rigging points available.

Preset Selector
- LINEAR: This preset is recommended for all regular applications of the speaker.
- 2 SPEAKERS: This preset creates the correct equalization for the use of two NX 985-A coupled on a subwoofer.
- HIGH-PASS: This preset activates a 60 Hz high-pass filter for the correct coupling of the NX 985-A with subwoofers not provided with their own internal filter
Power that Moves
The most powerful amplifier in its class. RCF's improvements in transducer design make them stronger and more powerful. With 2100W of power, the 2-channel NX 985-A's 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. NX 985-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. The NX 985-A amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high-efficiency with minimum weight.
Superior Transducers
- Lightweight and powerful, RCF drivers are a reference in high performance. All transducers are designed by RCF engineers in Italy for maximum reliability and perfectly matched components.
- The extended clarity of the 1.75" compression driver features a neodymium magnet for improved current handling and reduced weight. The best-in-class peek dome and the Polyamide/Kapton voice coil handle extreme power levels with very low distortion.
- The midrange section adds detail and vocal clarity with a high-power 8" cone midrange on a constant directivity waveguide.
- One high-power 15" low-frequency woofer with a new advanced transducer design gains more stability over higher currents, with less distortion, fast transient response, and better heat handling.
Bass Motion Control
- When searching for an 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. The speaker equipped with BMC can handle the lowest audible frequencies without affecting the woofer stability, with 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 new BMC algorithm breaks conventional rules.
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 985-A is a big-sized main system for highly demanding applications. Its flexibility makes it a smart choice for a wide range of live sound applications. The rugged, high-quality all-wood cabinet is easy to carry, with ergonomic handles on each side. It can be coupled for improved coverage and can also be flown or truss-mounted using the included M10 rigging points and special accessories. From the cabinet to the final texture and the rugged protective grille, NX 985-A offers maximum strength for intensive use on the road and can be used for fixed installation.
SUB 8008-AS
Pair one or two NX 985-A with an optional SUB 8008-AS to create a high-power, four-way sound system for any application that requires an earth-shaking response and extreme clarity on the entire frequency range.
