FOR IMMEDIATE RELEASE
RCF SUB AX Series integrates full speaker management into portable subwoofers
— Stereo crossovers, advanced EQ, delays, and presets simplify system deployment —
The NAMM Show, Anaheim, CA, January 22, 2026 – RCF (booth 17410, ACC North Hall level 2) continues to expand its portfolio of advanced portable sound reinforcement solutions with the introduction of the SUB 15-AX and SUB 18-AX, two high-power active subwoofers designed for demanding live sound applications where performance, portability and intelligent system control are equally critical.
The SUB 15-AX and SUB 18-AX feature latest-generation 15-inch and 18-inch transducers respectively, paired with powerful Class-D amplification to deliver impressive maximum sound pressure levels of up to 133 dB (SUB 15-AX) and 135 dB (SUB 18-AX) with exceptional clarity and headroom. Purpose-built for small to mid-sized venues and portable deployments, both models provide the low-frequency foundation required for professional touring, corporate events, rental applications and fixed installations.
Designed as the ideal complement to 10”, 12” or 15” full-range loudspeakers, the SUB AX series centralizes loudspeaker management directly inside the subwoofer. Advanced onboard DSP includes dual stereo crossovers, 8-band parametric EQs, routing, system delays, cardioid configurations and recallable crossover presets, allowing users to configure complete stereo systems quickly and accurately without external processors.
User control is streamlined through a full-color touch panel on the rear of the cabinet, along with wireless remote control via Bluetooth®, enabling intuitive system tuning directly from a mobile device.
“Bluetooth® remote control fundamentally changes how FOH engineers interact with their subwoofer systems,” says Tarik Solangi, Vice President of RCF USA. “With the SUB AX Series, users can walk the room, tune in real time, store presets, and make precise adjustments from a mobile device, without ever touching the back of the cabinet. It’s faster, smarter and far more intuitive than traditional control workflows.”
Both subwoofers are housed in rugged all-wood enclosures with scratch-resistant polyurea coating for long-term durability in demanding environments. The cabinets are engineered for easy portability and secure installation, including support for cardioid subwoofer configurations. Power connectivity is handled via a sealed Powercon True1 Top connector for maximum reliability.
With the introduction of the SUB 15-AX and SUB 18-AX, RCF delivers a new generation of intelligent, high-output subwoofers that combine musical performance, advanced control and road-ready construction – purpose-built for today’s modern live sound workflows.
