Overview

The RCF SUB 702-AS MK2 is a powered subwoofer engineered for professional live sound reinforcement where powerful, articulate bass is needed without the bulk of larger cabinets. At its core is a 12-inch woofer driven by a 1,400-watt digital Class D amplifier, a combination that delivers punchy, well-defined low frequencies capable of anchoring the bottom end for bands, DJs, presentations, and installed sound applications. The Class D topology keeps the amplifier efficient and the overall weight manageable at 47.8 pounds.

Designed for real-world flexibility, the SUB 702-AS MK2 includes switchable crossover frequencies so you can set the optimal handoff point between the sub and your top cabinets, along with a phase reverse switch to fine-tune time alignment for the tightest bass response in your specific room. Stereo XLR inputs accept signal from your mixer or processor, and the stereo crossover outputs pass the high-frequency content to your tops, making system wiring clean and straightforward. Measuring 21.3 x 16.3 x 21 inches, this subwoofer fits easily into vehicle loads and tight stage areas where a larger sub simply would not be practical, making it a versatile workhorse for mobile and installed applications alike.
