RCF ART 945-A: 135 dB Headroom, Premium Neodymium Precision
Command large rooms with authority using the RCF ART 945-A. A 2100W Class-D bi-amplifier drives a 15" neodymium woofer (3.5" v.c.) and a 4" titanium/neodymium compression driver through RCF’s True Resistive Waveguide for 100° × 60° coherent coverage and up to 135 dB SPL.
FiRPHASE and Bass Motion Control DSP maintain a 45–20000 Hz linear response with phase-true imaging and extended, controlled low end. The sleek polypropylene composite cabinet with M-brace reinforcement adds rigidity and damping, while a steel grille protects both transducers and ports.
For fast, reliable deployment, ART 945-A includes a balanced XLR/TRS combo input, XLR link out, a 35 mm pole insert, M10 rigging points, and PowerCON TRUE1 TOP in/out for ruggedized power connectivity.
Real-World Applications and Sound Roles
- High-output tops for mobile DJs and club installs.
- Powerful floor monitor using the Stage preset.
- Pole-mounted main over subs for dance floors.
- Flown or wall/truss-mounted zones in larger venues.
Where the RCF ART 945-A Excels
- Maximum Impact: Up to 135 dB SPL preserves headroom on peak-heavy material.
- Neodymium Authority: 15" LF with 3.5" voice coil delivers tight, punchy bass.
- High-Definition Top End: 4" titanium/neodymium driver allows a 650 Hz crossover for vocal clarity.
- Coherent Coverage: True Resistive Waveguide maintains a stable 100° × 60° pattern.
- Phase-True Mix Translation: FiRPHASE preserves imaging across the audience.
- Extended Low End Control: Bass Motion Control manages excursion for clean 45 Hz performance.
- Tour-Ready Power: PowerCON TRUE1 TOP in/out for sealed, locking AC connectivity.
- Silent Reliability: Convection cooling—no fan noise in installs or quiet stages.
- Rigging Flexibility: 35 mm pole insert and M10 points for pole, flown, wall, or truss setups.
Control Modes for the RCF ART 945-A
- Presets: Linear (general use), Boost (low-level background music), Stage (monitor).
- Indicators: SIGNAL LED confirms input; OVERLOAD LED warns of excessive input level.
- Gain & Routing: Balanced XLR/TRS combo input; XLR link output for daisy-chaining.
- Processor & Protections: FiRPHASE and Bass Motion Control; thermal/RMS protections with soft limiter.
- Crossover: 650 Hz acoustic handoff between LF and HF.
- Input Sensitivity: -2 dBu / +4 dBu selection to match sources.
- Power Connectivity: PowerCON TRUE1 TOP in/out.
Power That Moves
The two-channel 2100W Class-D amplifier is 50% more powerful than previous designs, delivering ultra-fast attack and realistic transient response at high SPL with minimal heat loss. The module couples to a solid aluminum heat exchanger for silent convection cooling.
M-Brace Cabinet Engineering
A special polypropylene composite enclosure with a purpose-designed M-brace interconnects the cabinet sides and amplifier, preventing deformation and increasing damping at maximum volume. A heavy-duty steel grille protects both transducers and vented ports.
Bass Motion Control
Bass Motion Control maps woofer behavior and limits only over-excursions, removing the need for a traditional high-pass filter. Expect extended LF linearity and improved integrity while maintaining phase behavior.
True Resistive Waveguide + FiRPHASE
The True Resistive Waveguide with optimized port geometry acts as a resonance-free, resistive acoustic load to reduce HF distortion and preserve imaging. FiRPHASE linear-phase filters keep the mix coherent across the audience area.
Legendary Neodymium Transducers
The ND940 4" titanium compression driver enables the low 650 Hz crossover for effortless vocals, while the 15" neodymium woofer (3.5" v.c.) delivers authoritative, transparent mid-bass without distortion.
True Outdoor Protection Power
PowerCON TRUE1 TOP connectors provide sealed, UV-resistant power in/out for heavy-duty and harsh environment applications common to entertainment staging.
How to Deploy the RCF ART 945-A in the Field
Select the configuration that fits the room and role: pole-mount on a 35 mm stand or over a subwoofer, use as a wedge monitor, or mount via M10 points for flown, wall, or truss applications. Aim to cover the audience evenly with the 100° × 60° pattern, then choose the preset that suits the task.
- Main PA: Use Linear; set height and toe-in to overlap patterns without hotspots.
- Monitor: Use Stage; aim across mic nulls to reduce feedback.
- Install: Use rigging points; confirm hardware, load limits, and mounting surfaces.
- Gain Staging: Match source level with the -2 dBu / +4 dBu setting; watch SIGNAL/OVERLOAD LEDs.
- Power: Daisy-chain AC where appropriate via PowerCON TRUE1 TOP out (observe limits).
Dial pattern, set the right preset, and ART 945-A delivers phase-true impact from front row to back wall.
