RCF SUB 905-AS MK3 15-inch 2,200-watt Active Subwoofer

RCF SUB 905-AS MK3 active high-power subwoofer

RCF SUB 905-AS MK3 active subwoofer is designed for professional sound reinforcement applications requiring powerful, controlled, and extended low-frequency reproduction. It features a 2200W peak Class-D amplifier that delivers extremely high sound pressure levels with excellent efficiency, low distortion, and fast transient response, making it suitable for demanding live sound environments, DJs, and touring systems.

The system is equipped with a high-performance 15-inch woofer featuring a 3.0-inch voice coil and ceramic magnetic structure, housed in a rugged bass reflex cabinet. It delivers a maximum SPL of up to 133 dB, providing deep, impactful bass reinforcement for small to large-scale sound systems.

Advanced DSP processing includes selectable crossover frequencies, gain control, polarity inversion, EQ, cardioid mode, and output delay settings. These features allow precise system alignment, optimized low-frequency control, and reduced stage and rear sound spill for improved performance in professional setups.

Bass Motion Control technology enhances woofer excursion management, ensuring extended low-frequency response with improved linearity and reduced distortion even under high-power operation. This results in tight, accurate, and controlled bass reproduction.

The cabinet is constructed from high-quality multi-ply hardwood with a durable scratch-resistant polyurea coating for touring reliability. Ergonomic side handles and a stackable design ensure easy transport and fast setup. A top-mounted M20 pole socket allows flexible system integration with satellite speakers.

With stereo XLR inputs and outputs, PowerCON IN/OUT connectivity, and robust internal protection systems, SUB 905-AS MK3 delivers reliable performance for professional applications requiring precision, power, and flexibility in low-frequency reinforcement.
