RCF Pro Sound SUB 8003-AS MK3 18" Active Subwoofer with DSP

The RCF SUB 8003-AS MK3 is a professional-grade, active subwoofer designed to deliver powerful and precise low-frequency reinforcement for demanding audio applications. As part of RCF's Pro Sound series, this 18-inch bass reflex cabinet incorporates a built-in digital signal processor (DSP) and a high-power amplifier, making it a self-contained solution for extending the low-end performance of PA and sound reinforcement systems. Its design focuses on reliability, portability, and sonic clarity, suitable for both fixed installations and touring use. The subwoofer is built around a proprietary 18-inch transducer with a ceramic magnet structure and a large 4-inch voice coil, capable of handling significant power. The integrated amplifier delivers up to 2200 watts of peak power, producing maximum sound pressure levels of 135 dB. Key technological features include RCF's Bass Motion Control processing, which enhances clarity and definition in the lower frequencies, and a comprehensive rear panel with user-adjustable controls. These controls include selectable input gain, crossover frequency, polarity, output delay settings, and a cardioid mode option for improved front-to-back rejection in certain setups. Connectivity is provided via stereo XLR input and output connectors, and the cabinet is constructed from durable birch plywood, finished in a black textured coating. This subwoofer is ideally suited for working audio professionals, including live sound engineers, rental companies, and installers who require robust, tour-ready low-frequency support. Its combination of high output, advanced DSP control, and a relatively compact, stackable form factor makes it practical for a wide range of applications, from live music venues and clubs to mobile DJ setups and corporate events. The thoughtful design, including convection cooling and comprehensive protection circuits, ensures dependable performance even under strenuous operating conditions.
