RCF SUB 15-AS Professional Powered Subwoofer

RCF SUB 15-AS active professional subwoofer

RCF SUB 15-AS active subwoofer is designed to provide powerful and controlled low-frequency performance for professional live sound, DJs, and small to mid-sized venue applications. It integrates a high-efficiency 2200W Class-D amplifier with a precision-engineered 15-inch woofer featuring a 3.0-inch voice coil, delivering deep bass output with high clarity and up to 133 dB SPL.

The system is optimized for use with 8-inch, 10-inch, and 12-inch loudspeakers, making it a versatile bass extension solution for a wide range of PA systems. It incorporates Bass Motion Control technology, which enhances low-frequency extension while maintaining woofer stability and reducing distortion even at high output levels.

The rear panel provides flexible control and connectivity options, including mono/stereo XLR/TRS combo inputs, stereo XLR link outputs, and XLR crossover outputs. Users can adjust volume, polarity, and low-pass filter frequency directly from the control interface, allowing precise tuning for different acoustic environments.

The cabinet is built from durable Baltic birch plywood and finished with a rugged polyurea coating for touring reliability. Ergonomic side handles and a stackable design improve portability and setup efficiency. A steel grille protects the woofer, while an M20 pole mount enables integration with satellite speaker systems.

With a combination of high output, robust construction, and flexible control options, SUB 15-AS is a reliable subwoofer solution for professional portable sound reinforcement systems requiring strong and accurate bass performance.
