The SUB 702-AS mk3 redefines portable bass performance with its cutting-edge 12" active subwoofer design that pushes sound pressure levels up to 129 dB. This high-power unit combines a state-of-the-art transducer featuring a ceramic magnetic circuit with a robust Class-D amplifier, making it the perfect companion for 8" or 10" loudspeakers in live sound applications. The rear panel provides comprehensive control with volume, EQ, polarity, and crossover frequency selection, while the rugged all-wood cabinet with scratch-resistant polyurea coating ensures durability and portability for small to mid-sized venues.
RCF subwoofers have earned their reputation among sound engineers for producing exceptional SPL levels at very low frequencies, combined with compact dimensions and impressive power-to-weight ratios. The 1400W peak power Class-D amplifier manages extreme sound pressure levels with ultra-fast attack and realistic transient response, while maintaining energy efficiency that eliminates the need for cooling fans. The amplifier connects to a solid aluminium heat exchanger with no moving parts, and features a stereo input circuit with advanced safety limiter that preserves signal integrity at all levels.
Revolutionary BMC (Bass Motion Control) technology sets this subwoofer apart by replacing traditional high-pass filters with an intelligent woofer excursion management system. This forward-thinking approach creates a complete map of the woofer’s dynamic behaviour, generating a custom algorithm that prevents over-excursions while maintaining extended linearity and superior sound integrity. The BMC method allows the transducer complete freedom for signal reproduction, handling the lowest audible frequencies without compromising woofer stability or altering phase behaviour like conventional high-pass filters.
Built for professional touring and installation demands, the all-plywood cabinet features ergonomic handles with rubber grips for easy setup and transport. The M20 threaded pole mount supports additional speakers, while the heavy-duty polyurea coating, powder-coated metal grille, and robust cabinet construction withstand rigorous use and transportation. Frontal vented ports allow flexible placement including recessed spaces, and acoustically transparent sound foam backing protects internal components from dust and humidity while maintaining optimal performance.
