RCF SUB 18-AS 2,200-watt 18″ Professional Powered Subwoofer

RCF SUB 18-AS active professional subwoofer

RCF SUB 18-AS active subwoofer is designed for high-impact low-frequency reinforcement in professional live sound environments such as concerts, clubs, DJ setups, and touring systems. It features a powerful 2200W Class-D amplifier paired with an 18-inch high-performance woofer with a 4.0-inch voice coil, delivering deep, accurate bass reproduction with exceptional headroom and clarity up to 135 dB SPL.

Engineered to complement 10-inch, 12-inch, and 15-inch full-range loudspeakers, it provides strong and controlled sub-bass support for scalable PA systems. Bass Motion Control technology ensures extended low-frequency performance while maintaining woofer stability and minimizing distortion, even at high output levels.

The rear panel offers flexible connectivity and control options, including mono/stereo XLR/TRS combo inputs, stereo XLR link outputs, and XLR crossover outputs. Users can easily adjust volume, polarity, and low-pass filter frequency for precise system tuning and integration.

The enclosure is constructed from durable Baltic birch plywood and finished with a rugged polyurea coating for maximum touring reliability. It features ergonomic side handles for easier handling, a stackable design for efficient transport, and an M20 pole mount for use with satellite speakers. A reinforced steel grille protects the woofer while maintaining acoustic transparency.

SUB 18-AS combines high power output, robust construction, and flexible configuration options, making it a reliable solution for professional portable sound systems requiring deep, powerful, and controlled bass performance.
