This system offers exceptional versatility with multiple mounting options—pole mount, flown rigging via M10 eyebolts, wall mounting, truss mounting, and ground stacking—plus compatibility with standard speaker stands, M20 pole mounts, and professional transport cases. What sets this package apart is the built-in intelligence: Bluetooth control, 6-channel digital mixers in each top speaker, advanced DSP processing, and factory crossover presets that eliminate complex setup headaches.
ART 915-AX: The Smartest PA Speaker You’ll Ever Use
The RCF ART 915-AX isn’t just a powered speaker—it’s a complete sound system in a single enclosure. Each speaker features a powerful 2,100W Class-D bi-amplifier (1,400W to the 15-inch woofer, 700W to the 1.75-inch compression driver) delivering 131dB maximum SPL with an impressively wide frequency response of 45-20,000 Hz. The True Resistive Waveguide technology creates 100°x60° constant directivity coverage, ensuring every seat in the house receives consistent, high-quality sound without the typical horn distortion you’d find in lesser speakers. What makes the ART 915-AX revolutionary is its built-in brain: a 6-channel digital mixer with advanced DSP that includes dual 48V phantom-powered preamps for microphones, line inputs, a stereo input, plus compressors, EQ, reverb, and a ducker effect. You can plug your microphones and instruments directly into the speaker—no external mixer required for many applications. The intuitive color touchscreen interface on the back panel makes adjustments a breeze, but here’s where it gets even better: Class 1 Bluetooth connectivity with over 100 meters (328 feet) of range lets you control everything wirelessly via the RCF LiveRemote app on your smartphone or tablet. Adjust mix levels, recall presets, dial in EQ settings, control effects—all from anywhere in the room. RCF’s proprietary FiRPHASE technology eliminates phase issues in the critical low-mid frequencies, ensuring crystal-clear sound with minimal latency and perfect stereo imaging. Bass Motion Control (BMC) is a game-changer for low-frequency management—instead of using traditional high-pass filters that can cause phase problems, BMC intelligently monitors woofer excursion and only limits motion when necessary, allowing the 15-inch driver to reproduce down to 45 Hz with remarkable clarity and power. The lightweight polypropylene composite cabinet with M-brace reinforcement weighs just 21.8 kg (48 lbs) per unit, making setup and teardown genuinely manageable for solo operators, yet it’s built tough enough for years of touring abuse.
SUB 18-AX: Your System’s Command Center and Bass Foundation
The SUB 18-AX is far more than just a subwoofer—it’s the intelligent hub that turns your PA into a cohesive, factory-tuned system. Each unit houses RCF’s precision-engineered 18-inch woofer with a massive 4-inch voice coil, powered by a robust 1,100W RMS (2,200W peak) Class-D amplifier that delivers earth-shaking bass down to 35 Hz with a maximum output of 135dB SPL. The bass-reflex design has been meticulously optimized for powerful, musical low-end that punches without muddiness. But here’s what makes the SUB 18-AX truly special: it centralizes complete speaker management for your entire PA system. The rear panel features a 2.4-inch full-color touchscreen (also controllable via the LiveRemote app) that gives you access to dual digital crossovers, 8-band parametric EQ, signal routing, time delay (up to 136ms), and perhaps most importantly, factory-tuned crossover presets for all RCF full-range speakers. This means when you pair the SUB 18-AX with your ART 915-AX tops, you simply select the “ART 9” preset and the system automatically configures optimal crossover points, phase alignment, and EQ—taking the guesswork out of system integration. The advanced FiRPHASE technology extends down to the lowest frequencies, maintaining perfect phase coherence between subs and tops for seamless sonic integration. For sophisticated deployments, the SUB 18-AX supports cardioid configurations—connect a second subwoofer, activate cardioid mode via the touchscreen, and the system automatically handles phase control to create directional bass that hits the audience hard while dramatically reducing stage wash and rear-room bleed. You can even set up 2.2 stereo operation when pairing two subs with stereo tops. The rugged multi-ply hardwood cabinet with polyurea coating is built for the road, featuring ergonomic rubber-grip handles, stackable design, M20 threaded pole mount on top, and PowerCon TRUE1 TOP sealed connectors for reliable power distribution. At 43.8 kg (96.5 lbs) per unit, these subs are surprisingly manageable given their output capabilities.
Perfect Coverage for Your Indoor and Outdoor Events
This RCF PA system package excels in real-world applications where both power and intelligence matter. For indoor venues—including houses of worship, conference centers, banquet halls, and theaters—this system effortlessly handles 250-500 people with exceptional clarity for both speech and music. The built-in digital mixers mean worship teams can run microphones and instruments directly into the tops without lugging an external console, while the Bluetooth control lets you adjust the mix from the congregation to hear exactly what they’re hearing. The wide dispersion pattern ensures even coverage throughout rectangular rooms, and the advanced DSP processing maintains intelligibility even in acoustically challenging spaces. For outdoor events—festivals, concerts, corporate gatherings, outdoor weddings—expect rock-solid coverage for 200-400 people, with the system maintaining punch and clarity even in open-air environments where sound dissipates quickly. The exceptional headroom means you can push volume when needed without distortion.
Subwoofer placement dramatically impacts your system’s performance, and with two SUB 18-AX units, you have multiple strategic configurations. Center-stacked placement (both subs together, typically under the stage) creates a powerful, focused low-end point source that works beautifully for most applications—simple to set up, easy to understand, and delivers solid bass throughout the venue. Split placement (one sub on each side, under or beside the tops) provides more even bass distribution across wider rooms but may create some nodes and nulls depending on room acoustics and sub spacing. For advanced users seeking directional bass control, cardioid configuration is where the SUB 18-AX truly shines—place two subs side-by-side facing opposite directions (one toward audience, one toward backstage), activate cardioid mode via the touchscreen, and the system automatically handles the phase relationship to create a directional bass pattern. This dramatically reduces low-frequency energy behind the subs (typically 15-20dB of rear rejection), keeping your stage clean and preventing that boomy, muddy bass from washing over performers. End-fire arrangement (subs in a line with one slightly behind the other, with delay applied to the rear unit) achieves even tighter directional control, though it requires more floor space.
This system is purposefully designed for the demanding needs of churches and worship spaces where volunteer sound operators need systems that sound great without requiring a Ph.D. in audio engineering—the factory presets and built-in mixers make Sunday services stress-free. Event production companies appreciate the system’s scalability, intelligent processing, and the ability to control everything via smartphone app—setup times are dramatically reduced, and you can fine-tune the sound from anywhere in the venue. Corporate events and conferences benefit from the exceptional speech intelligibility and the convenience of built-in phantom power for podium mics, plus the Bluetooth connectivity means presenters can stream backing tracks without cables. Live music venues and performing arts centers love the system’s musicality, headroom, and the fact that bands can run their inputs directly into the speakers for smaller shows without external mixers. Mobile DJs find the combination of powerful output, built-in mixing, and wireless control perfect for weddings, parties, and mobile events where simplicity and reliability are paramount.
Easy Rigging and Transportation
Setting up this RCF system is refreshingly straightforward, whether you’re deploying it for a one-night event or permanent installation. The ART 915-AX speakers offer ultimate mounting flexibility: pole mount configuration is the most common setup—simply place the tops atop the SUB 18-AX subwoofers using standard 36mm poles (M20 threading) for the classic PA arrangement. Flown rigging for permanent installations is accomplished via the integrated M10 threaded eyebolts on each speaker, allowing overhead suspension for theaters, venues, and houses of worship. Wall and truss mounting use the same rigging points, making the ART 915-AX incredibly versatile for fixed installations where floor space is limited. Tripod stands work perfectly with standard speaker stands, positioning the tops at optimal ear height for smaller venues or distributed systems. The lightweight cabinet design means one person can safely lift and position each top speaker without strain. The SUB 18-AX subwoofers can be deployed vertically (standing upright with tops pole-mounted—most common) or horizontally for low-profile stage setups, and they’re designed to be stackable for those needing extra low-end punch.
For professional transport and protection, RCF and third-party manufacturers offer purpose-designed protective covers and flight cases specifically for the ART 9 series and SUB AX series. The CVR ART 915 protective cover is available directly from RCF for weather protection and scratch resistance during storage and transport. For touring professionals, custom flight cases from manufacturers like Swan Flight Cases, Extreme Case, and others provide heavy-duty protection with foam interiors, reinforced corners, and wheels for easy maneuverability. Many case manufacturers offer configurations for single speakers or pairs, plus options for stacking cases to minimize truck space. The rugged cabinet construction—polypropylene composite for the tops, polyurea-coated hardwood for the subs—means these speakers can withstand regular transport even without cases when handled carefully. The SUB 18-AX features ergonomic rubber-grip handles integrated into the sides, making two-person carries manageable despite the 96-pound weight. Optional wheel kits or board-mounted casters can transform the subs into rolling cases for easier load-in. Each ART 915-AX weighs just 48 pounds, making them genuinely portable—a huge advantage during setup and strike, especially when working solo or with limited crew. For regular mobile use, investing in padded bags or flight cases protects your investment and maintains that professional appearance year after year. The PowerCon TRUE1 TOP sealed connectors on all units ensure reliable power connections that won’t accidentally disconnect during transport or use—a critical feature for professional applications.
