RCF SUB15-AX Professional Active 15 Inch Subwoofer
If you want a low-end that you can feel rattling your ribs, the RCF SUB15-AX is your heavy-hitting champion. This portable 15-inch active subwoofer takes live sound to a whole new level, blending brute force with brainy digital processing. It acts as the ultimate anchor for small to mid-sized venues, pushing massive air without turning your mix to mud.
You get the thumping chest-punch of vintage rigs combined with the razor-sharp precision of modern technology, all packed into a box you can actually carry into the club.
Heart-Pounding Power
Most subwoofers just make noise; the SUB15-AX makes an impact. Driven by a beastly 2200-watt Class-D amplifier, it delivers sound pressure levels up to a staggering 133 dB. It pushes pristine, chest-caving clarity with massive headroom, ensuring your bass lines stay tight and punchy even when you push the faders to the absolute limit.
2200-Watt Class-D Amplifier: Delivers devastating, distortion-free power that keeps the dancefloor moving all night long without breaking a sweat.
133 dB Max SPL: Unleashes a tidal wave of volume, giving you the raw acoustic muscle needed to fill small and medium-sized rooms effortlessly.
Bass Motion Control: Intelligently manages woofer excursion, letting you push the absolute boundaries of low-end frequencies without compromising sonic integrity.
Your Command Center
Forget the outboard gear. The SUB15-AX centralizes your entire speaker management system right inside the box. With a brilliant color touch panel and Bluetooth remote control via the LiveRemote App, you can tweak your room from the palm of your hand. It’s the perfect partner for 10-inch or 12-inch top boxes, giving you complete control over crossovers, delays, and EQs.
Color Touch Panel & LiveRemote App: Dial in your settings directly on the back of the sub, or walk the room and make adjustments via Bluetooth on your smartphone.
Advanced DSP Engine: Features dual crossovers, 8-band EQs, routing, and delays, giving you surgical precision over your sound without an external drive rack.
Cardioid Configurations: Easily recall presets to set up advanced cardioid arrays, keeping the bass focused on the audience and off the stage.
Ready for the Road
Life on the road is rough, but this sub is built for it. Its all-wood cabinet is coated in a rugged polyurea finish that resists scuffs, scratches, and the inevitable spilled drink. And at just under 50 pounds, it's a portable powerhouse that saves your back during load-in while delivering the performance of a permanent installation.
Polyurea-Coated Wood Cabinet: A rock-solid, multi-ply hardwood enclosure built to survive the merciless reality of touring and late-night load-outs.
Sealed Powercon True1 Top: Features a secure, weather-resistant AC connector so your power stays locked in, even when the stage gets chaotic.
Lightweight Portability: At just 48 pounds, one person can easily maneuver this bass beast out of the van and onto the stage.
The Definitive Bottom End
The RCF SUB15-AX is what happens when relentless power meets refined processing. It brings club-shaking bass to any portable gig, offering the smarts to tune your rig perfectly and the muscle to move the crowd. It’s the definitive low-end solution for audio professionals who refuse to compromise on sound quality or convenience.
