RCF ART 945-A

Otherworldly Sound for Demanding Audio Applications!

The ART 945-A delivers innovative technologies and otherworldly sound for demanding audio applications. The combination of a 4-inch titanium/neodymium compression driver, a 15-inch neodymium woofer, a 2-channel 2100 W amplifier, and a Constant Directivity TrueResistive Waveguide ensures consistent 100° x 60° coverage of the listening area with up to 135 dB SPL distortion-free sound.

Whether as a stand-alone FOH system, satellite (with subwoofer), stage monitor, or flown: the compact ART 945-A is powerful and reliable. As the most versatile active speaker in its class, it also features multiple mounting points for permanent installations. Thanks to RCF-exclusive FiRPHASE and Bass Motion Control algorithms, precisely tuned to each model, your audience experiences absolutely transparent sound reproduction and an extensive, punchy bass range. The sleek polypropylene enclosure is reinforced with an internal M-frame for stability. This makes it easy to transport and allows secure mounting on a stand, flown, on a wall, or a truss using multiple attachment points.

Power That Moves

The most powerful amplifier in its class. RCF transducers are continuously optimized—and so are the amplifiers. With 2100 W output, the ART 9 series’ 2-channel Class-D amplifier is 50 percent more powerful than its predecessors, achieving impressive SPLs with ultra-fast attack and natural transient response while minimizing heat loss. ART 9 speakers are so energy-efficient they don’t require a cooling fan. Instead, the amplifier is mounted at the rear of the enclosure on a fixed heat exchanger with no moving parts. Physically connected to the internal chassis, the amplifier stays firmly in place. The signal input path is optimized for low distortion and includes an advanced limiter for added protection, preserving the tonal characteristics of the input signal at all levels. All ART 9 amplifiers meet maximum safety standards (EN62368-1) and are powered by a highly efficient, ultra-lightweight switching power supply.

Stable Enclosure Thanks to M-Frame

The professional look of the ART 9 enclosures is perfect for live events and permanent installations. The sleek polypropylene cabinet is based on a completely new design principle. The front grille, made of extremely durable steel, protects both the transducers and the bass reflex ports. The specially developed M-frame connects the four inner sides of the enclosure and the amplifier to prevent cabinet deformation and ensure outstanding acoustic damping even at extreme levels. The frames also act as a supporting structure to better protect the enclosure against mechanical impacts.

Bass Motion Control

To achieve extended bass response and more power, our development team replaced the standard high-pass filter with a groundbreaking technology. Introducing BMC (Bass Motion Control), our innovative feature for controlling woofer excursion. ART 9 speakers with BMC handle even the lowest audible frequencies without compromising woofer stability—for a linear, extended bass range and balanced sound.

BMC is an algorithm that thoroughly analyzes the woofer’s dynamic behavior and restricts only excessive excursions based on this specific data. This allows complete freedom in signal reproduction by the transducer. Standard high-pass filters aim to prevent woofer damage but also affect phase behavior. Thanks to the new BMC algorithm, this issue is now a thing of the past. Combined with FiRPHASE technology, BMC elevates the ART 9 series to a new level of DSP audio performance previously unmatched in this speaker class.

Innovative Electroacoustic Design

The special secret of the ART 9 series lies in the speaker enclosure. The new True Resistive Waveguide combines several technological innovations—both in the transducers and the special enclosure design with bass reflex port—developed through finite element analyses and extensive measurements in our in-house reflection-free rooms. Thanks to FiRPHASE technology and the novel enclosure construction, this is the happy ending to your search for the perfect sound. The TRW waveguide acoustically simulates a resonance-free resistive load, reducing typical high-frequency horn distortions. Thanks to asymmetric sound processing, the waveguide ensures consistent coverage and an improved stereo image across the entire listening area.

Legendary Transducers

Top-Quality Compression Drivers: The ND940 compression driver with titanium diaphragm and 4-inch voice coil allows a very low crossover frequency of 650 Hz. This improves impulse response, shortens decay time, and increases efficiency. With their low weight and high power handling, RCF’s neodymium drivers set standards in reliability and performance.

Powerful Woofer: A powerful 15-inch neodymium transducer with a 3.5-inch voice coil delivers punchy bass. The low-midrange reproduction is precise, transparent, and distortion-free.

Extremely Durable

In the constantly evolving entertainment industry, the demand for rugged, secure connection options is growing. In harsh environments and under heavy loads, connections must be protected against environmental influences. The ART 945-A features True Outdoor Protection (TOP) PowerCON TRUE1 power connectors. These robust connectors are completely sealed and provide not only IP-standard protection (IP65 when connected) but also UL 50E-compliant UV protection.

A New Perspective on Linearity

RCF speakers are developed based on proprietary, advanced FIR filter technology that guarantees a transparent sound image, absolute clarity, and a perfect stereo image. The special FiRPHASE filters enable even sound distribution for all listeners without phase distortion and with minimal latency throughout the system.
