RCF SUB 8003-AS MK3 active high-power subwoofer

RCF SUB 8003-AS MK3 active subwoofer is designed for demanding professional audio applications requiring extremely powerful, deep, and controlled low-frequency reproduction. It features a 2200W peak Class-D amplifier that delivers outstanding sound pressure levels with high efficiency, low distortion, and fast transient response, making it suitable for large venues, touring systems, and high-energy live performances.

The system incorporates a high-performance 18-inch woofer with a 4.0-inch voice coil and ceramic magnetic structure, housed in a rugged bass reflex cabinet. It delivers up to 135 dB SPL, providing impactful and extended low-end performance that enhances any professional PA system with deep and precise bass response.

Advanced DSP processing allows full control over gain, EQ, polarity, crossover frequency, cardioid mode, and output delay. These features ensure precise system alignment, improved low-frequency control, and reduced unwanted stage or rear bass energy, making it ideal for professional live sound environments.

Bass Motion Control technology enhances woofer excursion management, allowing extended low-frequency reproduction while maintaining linearity, stability, and low distortion even at extreme output levels. This results in tight, powerful, and accurate bass performance.

The cabinet is built from durable multi-ply hardwood with a scratch-resistant polyurea coating, designed for heavy touring use. It is stackable for efficient transport and setup, and includes ergonomic side handles for easy handling. A top-mounted M20 pole socket enables flexible system integration with satellite speakers.

With robust internal protection, stereo XLR connectivity, PowerCON IN/OUT power support, and road-ready construction, SUB 8003-AS MK3 delivers professional-grade subwoofer performance for high-demand sound reinforcement systems.
