🔊 Next-Generation Control Meets Powerful Low-End
The RCF SUB 15-AX is a next-generation active subwoofer that combines high-output performance with advanced system control. Delivering up to 133 dB SPL from a powerful 2200W Class-D amplifier, it provides deep, tight low-frequency response with exceptional clarity and headroom.
Designed for modern sound systems, the SUB 15-AX goes beyond traditional subwoofers by integrating full DSP control and wireless operation—making it an all-in-one low-frequency solution for demanding professionals.
📱 LiveRemote App
Whether you’re a musician, DJ, or pro sound engineer, the RCF LiveRemote App—also used with ART 9 AX speakers—is fully compatible with the SUB AX models.
On the subwoofers, crossover preset selection, system EQ, delay adjustments, and individual crossover settings are quickly accessible. When two subwoofers are paired, they can be configured for 2.2 system operation.
Available for Android and iOS smartphones and tablets, giving you full wireless control of your system.
⚡ Advanced DSP & Wireless System Management
At the core of the SUB 15-AX is a powerful internal DSP engine, accessible via a built-in color touch panel or remotely via Bluetooth®.
System control includes:
- Dual crossover management
- 8-band EQ for precise tuning
- Delay alignment for system optimization
- Cardioid configurations for directional bass control
- Recallable presets for fast setup
RCF’s proprietary Bass Motion Control (BMC) ensures consistent, controlled bass performance—even at high output levels.
🧳 Designed for Modern Portable & Installed Systems
The SUB 15-AX is engineered as the ideal companion for 10” and 12” top speakers, centralizing system processing within the subwoofer for faster deployment and cleaner setups.
Its durable multi-ply hardwood enclosure, finished in a rugged polyurea coating, is built for both touring and installation environments.
The PowerCON TRUE1 TOP connector ensures reliable power connectivity in demanding conditions.
