RCF NX 9 Series

FOH Staff • International NewsNew Gear • July 15, 2021

REGGIO EMILIA, Italy – RCF presents three new speaker models from the NX Series portable audio system category with unique electroacoustic features.

More details from RCF (www.rcf.it):

RCF engineers have merged purpose-designed transducers, a constant directivity waveguide, FiRPHASE processing, and newly added Bass Motion Control algorithms, all driven by a powerful amplifier with 2100 Watts Class-D technology. Durably built in a rugged wooden enclosure, NX 9 is tour-ready, and delivers remarkable audio performance and versatility to any professional audio application.

Now 50% more powerful than previous models, NX 9 manages extremely high sound pressure levels. The amplifier is energy-efficient so there is no need for a cooling fan. The circuit is attached to a solid aluminum heat exchanger in the back of the unit with no moving parts. Performance improvements are assured with the new 1.75-inch compression driver with Polyimide-Kapton dome featuring a new bonding technology and reinforced ribs that make it 10 times more durable than previous models. The combination of purpose-designed woofers and the constant directivity waveguide produces coherent coverage on the listening area.

These components work in harmony with two RCF exclusive DSP algorithms, one for phase linearization and crossover design, the other for woofer excursion management. FiRPHASE, a superior digital FiR technology, allows for a coherent distribution of sound without phase distortions, ensuring minimum latencies to the system. With proprietary FiRPHASE technology, the new shape, and the placement of the vented ports, the speaker now acts as a single source for a true sound image. The woofer excursion management feature, Bass Motion Control works by creating a complete map of the dynamic behavior of the transducer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction, avoiding both high-pass filters and large-band limiters. The speaker is now allowed to reproduce the input signal at all volume levels for the entire audible spectrum, maintaining all nuances of the music with deep, detailed bass response.

The sleek black cabinet is made of high-strength wood coated with a black and robust polyurea coating. The speaker is easy to move and transport with ergonomic handles on both sides. The bottom side includes a steel pole socket for mounting on a stand or subwoofer pole. Each model can also be flown, wall- or truss-mounted using multiple M10 rigging points and special accessories.

The NX 9 series consists of three new models, ranging from 10” to 15” woofers, and shares the same 2100 Watts power amplifier. NX 915-A is the largest, most powerful model of the series delivering an impressive 131 dB maximum SPL and is able to deliver stable low-frequency response down to 45Hz. NX 912-A and NX 910-A can produce 130 dB SPL with remarkable clarity and exceptional power to weight ratio.
