Bass Motion Control Intelligent control of woofer excursion
RCF presents three new loudspeaker models from the NX Series portable audio system category with unique electroacoustic characteristics. RCF engineers have brought together specially designed transducers, a new waveguide with constant directivity, FiRPHASE processing and the new Bass Motion Control technology. Housed in rugged wooden enclosures, the NX 9 speakers are tour-ready and offer remarkable audio performance and versatility for any professional audio application.
The NX 9 Series has three new models with 10", 12" or 15" woofers. All models feature the same 2100-watt power amplifier. The NX 915-A is the largest and most powerful model in the series, delivering an impressive 131 dB maximum SPL and capable of robust low-frequency response down to 45 Hz. The NX 912-A and NX 910-A can each produce 130 dB SPL with remarkable clarity and exceptional power-to-weight ratio.
RCF NX 915-A is now up to 50% more powerful than previous models. The amplifier is energy efficient, so no fan is required. The new 1.75-inch compression driver with polyimide Kapton dome has been completely redesigned. Its durability is up to ten times greater than its predecessors. Redesigned bass drivers get more stability at high load and less distortion.
The combination of specially designed woofers and the Constant Directivity waveguide ensures coherent dispersion in the listening area.
RCF NX 915-A
The NX 915-A powered speaker offers innovative technologies and otherworldly sound for solo musicians, bands and DJs. The combination of a 1.75" compression driver, a 15" woofer, a 2-channel 2100 W power amplifier and a Constant Directivity Waveguide provides consistent 100° x 60° coverage of the listening area with up to 131 dB SPL of distortion-free sound.
Premium transducers
RCF's lightweight drivers deliver impressive performance. To ensure maximum reliability and optimum interaction of all components, all transducers have been specially designed by RCF engineers in Italy. The novel design makes the 1.75" voice coil with polyimide Kapton dome ten times stronger than its predecessors, ensuring more accurate output and improved longevity.

Bass Motion Control
These components work in unison with two RCF-exclusive DSP algorithms. One for phase linearization and crossover design, the other for woofer excursion management. FiRPHASE, an FIR technology, enables coherent distribution of sound without phase distortion and ensures minimal latency in the system. Bass Motion Control for controlling the woofer excursion knows the full image of the transducer's dynamic behaviour to limit over-excursion. This allows a completely free signal reproduction and avoids high-pass filters as well as broadband limiters and compressors. As a result, the speaker is able to reproduce the input signal at all volumes across the entire audible spectrum, preserving all the nuances of the music with deep, detailed bass response.
Rugged and easy to transport
The sleek cabinet is made of high-strength wood and finished in black polyurea. With ergonomic handles on both sides, the speaker is easy to move and transport. There is a tripod mount on the bottom. Each model can also be flown, wall or truss mounted using multiple M10 rigging points and special accessories.
