RCF SUB 18-AX Professional Active 18 Inch Subwoofer
When your live sound needs a foundation-shaking low-end that you can feel in your chest, the RCF SUB 18-AX is your new best friend. Forget muddy, undefined rumbles — the SUB 18-AX offers exceptional clarity and headroom, ensuring your low-end hits hard and clean every single time. This portable 18-inch active subwoofer isn't just about raw power; it’s a master of precision, control, and punch.
Why the SUB 18-AX Commands the Low End
There’s nothing quite like the feeling of perfectly dialed-in bass, and the SUB 18-AX makes achieving that sonic bliss easier than ever. It's more than a subwoofer; it’s the heart of your PA system, centralizing speaker management with an intuitive touch panel and remote app control. Think of it as your command center for all things low-end, built to withstand the rigors of the road while delivering studio-quality performance.
2200-Watt Class-D Amplifier: This powerhouse sub provides an earth-shaking 2200 watts of peak power, giving you all the headroom you need to fill a room without breaking a sweat. It’s clean, efficient power that translates directly into massive sound pressure levels up to 135 dB.
18-inch Woofer, Bass Reflex Housing: At the core of the SUB 18-AX is a latest-generation 18-inch transducer housed in a finely tuned bass-reflex enclosure. This combination is engineered for maximum output and minimal distortion, delivering deep, resonant bass that’s both powerful and musical.
Bass Motion Control: Say goodbye to wobbly, uncontrolled bass at high volumes. RCF's proprietary Bass Motion Control algorithm manages woofer excursion, preserving the full dynamic range of your signal while preventing over-excursion. The result is tighter, more powerful bass that retains its character even when you push it to the limit.
Complete Control at Your Fingertips
The SUB 18-AX puts you in the driver's seat with a suite of advanced processing tools designed to make your life easier. Gone are the days of wrestling with external processors and complex routing. This subwoofer has everything you need built right in, accessible through a slick color touch panel or wirelessly from your phone or tablet.
Fully Featured Processing: This subwoofer is the brain of your operation. It centralizes speaker management with dual crossovers, 8-band EQs, routing, and time delays. You can sculpt your sound with surgical precision to perfectly match your main speakers and adapt to any room acoustics.
LiveRemote App & Color Touch Panel: Tweak your settings from anywhere in the venue using the RCF LiveRemote app via Bluetooth. Or, make quick adjustments on the fly with the intuitive onboard color touch screen. It’s all about giving you flexible, convenient control over your sound.
Recallable Crossover Presets: Set up is a breeze. The SUB 18-AX comes with recallable crossover presets designed to perfectly match RCF's 10", 12", and 15" loudspeakers. You can even create and save your own presets for different setups and venues, making every gig consistent and hassle-free.
Built for the Road
Every component of the SUB 18-AX is designed with the working professional in mind. From its rugged cabinet to its versatile connectivity, this subwoofer is ready to handle whatever you throw at it, night after night.
Multi-ply Hardwood Cabinet: The all-wood cabinet is not just about great acoustics; it’s built like a tank. Coated in a heavy-duty black polyurea finish, it's resistant to scratches, scuffs, and the general abuse of load-ins and load-outs.
Flexible I/O: Connectivity is king. The SUB 18-AX features dual XLR/TRS combo inputs with link-through outputs, plus dual XLR crossover outputs for seamless integration into any professional sound system.
Sealed Powercon TRUE1 TOP Connector: Professional gigs demand reliable power connections. The sealed Powercon TRUE1 TOP connector ensures a secure, weatherproof link that won't accidentally disconnect, giving you peace of mind during a high-energy show.
The Foundation of Great Sound
Forget flimsy bass; the RCF SUB 18-AX is a smart, seismic solution, giving you the power to unleash astounding audio with effortless ease and rock-solid reliability. It brings together earth-shaking power with pinpoint control, all tucked into a tough, tour-ready package built for battle.
