RCF ART 945-A 15" Active Speaker 2100 Watts Amplified PA Stage Monitor w/ Integrated DSP
Overview
ART 945-A is masterfully engineered to deliver stellar audio performance and versatility for intensive audio applications.
The combination of neodymium transducers - 4" titanium compression driver, 15" woofer - two-channel 2100W amplifier, and the constant directivity True Resistive Waveguide produces coherent 100° x 60° coverage for the listening area with up to 135 dB SPL, distortion-free sound. Used as a stand-alone speaker for a FOH system, satellite (with subwoofer), stage monitor, or flown, the ART 945-A packs high-performance and reliability in a compact enclosure.
Designed to be the most flexible loudspeaker in its class, it also features multiple rigging points for fixed installation. Merging RCF proprietary FiRPHASE and Bass Motion Control DSP processing, perfectly tuned for each model, the audience will experience absolute clarity and deep, powerful bass response.
The sleek cabinet uses a special polypropylene composite material with an M-brace internal reinforcement, making it easy to carry and secure to install on a pole, flown-, wall-, or truss-mounted using the multiple rigging points available.

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. ART 9 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 rule. In combination with FiRPHASE technology, ART 9 has a level of DSP audio performance never achieved in this range of speakers.
NEW PARADIGMS IN ELECTROACOUSTICS
LEGENDARY TRANSDUCERS
SUPERIOR COMPRESSION DRIVERS
The ND940 Compression Driver in pure Titanium with a 4 inches 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.
POTENT WOOFER
The low-frequency transducer is a high-power 15?? neodymium 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.
READY FOR HEAVY-DUTY APPLICATIONS
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.
