RCF SUB 9007-AS - 7200W 2 x 21-inch Powered Subwoofer with RDNet and 4-inch Voice Coils in Black Finish

The RCF SUB 9007-AS is a powerful, dual 21" subwoofer designed to deliver exceptional low-frequency performance in large-scale sound systems. With a peak power rating of 7200 watts and 3600 watts RMS, this subwoofer can generate an astounding maximum SPL of 141 dB, making it ideal for demanding live sound environments, installations, and AV rentals. The SUB 9007-AS is engineered to perform in the most challenging scenarios, from outdoor festivals to large arena events, providing deep, impactful bass that is both clean and precise.

At the heart of the SUB 9007-AS are two 21" high-power neodymium woofers, each featuring a 4.0" voice coil for superior cooling and power handling. The woofers are housed in a rugged, tour-grade Baltic birch plywood cabinet, known for its durability and structural integrity. RCF's proprietary Hyper Ventilation system further enhances the subwoofer's performance by minimizing power compression, ensuring that it maintains peak output even during extended use. The woofers are designed with a combination of carbon fiber, fiberglass, and cellulose pulp in the cone, which provides excellent rigidity and resistance to deformation, ensuring high efficiency and long-term reliability. The 4.0" voice coils are wound on fiberglass formers reinforced with Nomex, ensuring that the subwoofer handles high power with minimal distortion.

The SUB 9007-AS is powered by a cutting-edge 7200W Class-D digital amplifier that provides extended low-frequency performance while maintaining high efficiency. The amplifier is integrated with a 32-bit DSP circuit, which handles all the essential functions such as soft clipping, RMS limiting, and equalization. With RDNet compatibility, users can easily control and monitor the subwoofer remotely, adjusting parameters such as level, delay, and EQ through the RDNet networked management software. RDNet allows for precise control over the entire system, making it ideal for complex installations and large-scale events where system optimization and real-time adjustments are essential.

Designed for easy setup and transportation, the SUB 9007-AS features an ergonomic design with eight aluminum handles (four per side), allowing for easy handling and quick deployment. The subwoofer is stackable and lightweight, making it ideal for touring and rental applications. Additionally, the cabinet includes mounting points and dual M20 pole mounts, allowing it to be used in multiple configurations with other RCF loudspeakers such as the HDL 50-A 4K, HDL 20-A, and HDL 10-A. The subwoofer's heavy-duty, powder-coated front grille incorporates a special transparent-to-sound foam backing that protects the transducers from dust and debris.

With a frequency response of 20 Hz to 400 Hz, the SUB 9007-AS is designed to handle the full spectrum of bass frequencies, ensuring tight, controlled low-end reproduction for any application. The unit includes a variety of input and output options, such as XLR and RDNet Ethercon connectors, for easy integration into any sound system. The SUB 9007-AS also features advanced DSP controls, including selectable presets, crossover settings, phase switch, and output delay settings, all accessible via the rear control panel or through RDNet remote management. Whether used for live performances, theater sound systems, or large installations, the RCF SUB 9007-AS is the ultimate subwoofer solution for deep, powerful bass in professional audio setups.
