New open-box RCF SUB 708-AS MK3 active subwoofer in excellent condition, only unsealed for inspection and photos. This powerful, portable 18-inch sub packs 1,400 watts of Class D amplification, delivering deep, tight bass down to 35Hz with a max SPL of up to 133dB, making it an outstanding choice for small- to mid-sized venues and mobile rigs. Designed as the ideal low-frequency partner for 8- and 10-inch tops, it offers ample headroom and low distortion for modern live sound, DJs, and installed systems.
The SUB 708-AS MK3 features a high-power ceramic-loaded 18-inch woofer in a bass-reflex enclosure, optimized for punch and extension. Onboard processing includes a built-in stereo crossover, selectable crossover frequencies, polarity reverse, digitally controlled EQ, soft limiting, and system protection, giving you clean, controlled low end and flexible integration with your existing PA. Stereo XLR inputs and outputs make setup straightforward, while bass motion control manages excursion for reliable performance at high levels.
Built for real-world use, the cabinet is constructed from rugged Baltic birch and finished with a scratch-resistant polyurea coating for long-term durability. A heavy-duty steel grille protects the driver, and integrated side handles make loading in and out simple.
