RCF SUB-9019-AS Active 4000W 19" Subwoofer (RDNET Ready)

Engineered for Demanding Touring Applications
The RCF SUB 9019-AS is a professional-grade active subwoofer designed to deliver powerful low-frequency output in large-scale live sound environments. Built with a 19" high-excursion precision transducer and a 4000W peak Class-D amplifier, this sub handles anything from dynamic stage performances to heavy-hitting DJ sets. With a wide 30 to 200 Hz frequency range and a maximum SPL of 138 dB, the SUB 9019-AS offers deep, clear bass reproduction in any professional setup.

Wireless Configuration with RDTap Setup App
Managing your subwoofer has never been easier thanks to the RDTap app, which enables wireless, contactless configuration—even while the sub is unpowered. By tapping your smartphone against the back panel, you can transmit setup parameters such as preset selection, delay alignment, equalization, and cardioid configuration. This tool streamlines system prep in fast-paced environments like tours and rentals, reducing setup time without compromising precision.

RDNet Integration for System-Wide Control
The SUB 9019-AS is RDNet-ready, allowing full integration into RCF's RDNet network for advanced system management. Audio engineers can monitor and adjust DSP parameters across individual units or groups of speakers, including EQ, delay, crossover, and cardioid behavior. The robust software platform ensures tight phase alignment and seamless integration with other RCF loudspeakers and subwoofers.

Advanced Crossover Engine Delivers Seamless Integration
RCF’s proprietary Advanced Crossover Engine (ACE) ensures flawless phase and timing alignment between the SUB 9019-AS and full-range FiRPHASE-enabled RCF loudspeakers. This means tighter bass response, improved clarity at crossover points, and better coherence across your entire system. ACE simplifies deployment in flown or stacked systems by handling acoustic alignment internally.

Powerful Class-D Amplification with Precision Input Circuitry
The built-in Class-D amplifier delivers 4000W peak output, managing high SPL levels with minimal distortion. An advanced stereo input circuit maintains clarity across all volumes with a low-distortion design and intelligent safety limiters. The power supply uses switched-mode technology for lightweight efficiency and thermal reliability, helping the SUB 9019-AS perform consistently in any venue or climate.

Roadworthy Construction for Harsh Environments
Constructed from weather-resistant plywood with a rugged polyurea coating, this subwoofer is built to withstand the rigors of touring. A magnetic I/O panel rain cover shields sensitive connectors from dust and moisture. Ergonomic side handles and M20 pole mounts make it easy to transport and position. The detachable cart connection system (cart sold separately) adds portability for production teams on the move.

Bass Motion Control Technology Improves Woofer Accuracy
Bass Motion Control (BMC) replaces traditional high-pass filters with an intelligent algorithm that dynamically limits woofer excursion only when needed. This lets the woofer operate freely across its full range, enhancing linearity and preserving phase integrity at extreme low frequencies. It results in smoother, more controlled bass reproduction without sacrificing depth or clarity.
