RCF SUB 8008-AS - 4400W 2 x 18-inch Powered Subwoofer with 4-inch Voice Coil in Black Finish

The RCF SUB 8008-AS is a robust and high-powered active subwoofer designed to deliver deep, powerful bass for large-scale live sound applications. Equipped with two 18" high-power woofers and a state-of-the-art 4400W Class-D amplifier, this subwoofer delivers exceptional performance, reaching up to 137 dB SPL. The SUB 8008-AS excels in both clarity and headroom, making it the perfect choice for live bands, DJs, clubs, and rental companies looking for reliable and high-output bass reproduction.

At the core of the SUB 8008-AS are two advanced 18" woofers featuring 4.0" voice coils and high-power ceramic magnetic circuits. The unique magnetic design ensures a consistent, high-integrity magnetic flux gap, delivering excellent performance across a wide range of frequencies. The speaker's robust construction minimizes distortion while maintaining lightweight efficiency, thanks to RCF's precision engineering and T-pole design optimization that minimizes flux modulation during typical voice coil movement.

The SUB 8008-AS features a powerful 4400W peak, 2200W RMS, Class-D bi-amplification system, delivering ultra-fast attack, realistic transient response, and low heat loss. This amplifier operates with exceptional energy efficiency, using a fan-less design with a solid aluminum heat exchanger attached to the rear of the cabinet. This efficient design ensures reliable operation in demanding environments without the need for active cooling, making it perfect for extended use in high-intensity live sound applications.

Designed for versatility, the SUB 8008-AS incorporates multiple rear-panel controls, including 12 factory-tuned crossover presets, a polarity switch, a Deep/Punch selection, and cardioid and output delay settings. These options allow you to fine-tune your sound system for optimal bass performance, regardless of the application or venue size. The ability to switch between different cardioid presets enhances the sound projection and reduces rearward radiation, making it ideal for front-of-house and stage applications.

The speaker's rugged all-plywood cabinet, finished with a durable, scratch-resistant polyurea coating, is built to withstand the rigors of touring and constant transport. It includes two ergonomic side handles for easy setup and tear-down, while its stackable design ensures efficient storage and portability. The cabinet also features two M20 threaded pole mounts, allowing for both vertical and horizontal configurations, providing flexibility for different speaker setups. The powder-coated steel grille, with acoustically transparent foam backing, further protects the transducers from dust and moisture, ensuring long-term durability.

The SUB 8008-AS is fully compatible with other RCF systems and integrates seamlessly with both active and passive components, making it a cornerstone of any professional PA system. The stereo XLR input and output connectors provide convenient connections to other speakers or audio equipment, and the Powercon TRUE1 TOP sealed AC connector ensures reliable and safe power distribution during events. With the added benefit of RCF's proprietary Bass Motion Control (BMC) technology, the SUB 8008-AS delivers exceptional low-frequency control, extending the bass response while maintaining the integrity of the audio signal.

Whether you're outfitting a large venue, a touring sound system, or a club, the SUB 8008-AS offers unparalleled performance, flexibility, and reliability. Its combination of powerful bass response, durable design, and easy integration into existing systems makes it an essential tool for audio professionals who demand the best in subwoofer performance.
