SUB 708-AS MK3 ACTIVE SUBWOOFER - RCF

The RCF SUB 708-AS MK3 is a portable 18" active subwoofer built for live sound applications that demand strong low-frequency performance, high output, and dependable control. Its 18" woofer in a bass reflex enclosure is powered by a 1400 W peak Class-D amplifier, delivering up to 133 dB SPL with substantial headroom. With a frequency response of 35 Hz to 120 Hz, it is designed to extend the low end of compact PA systems while maintaining a controlled, musical response. Rear-panel controls include volume, EQ, phase, and crossover frequency selection, making it easy to integrate the SUB 708-AS MK3 into a wide range of setups. Stereo XLR inputs and stereo XLR signal outputs support straightforward system connections, while electronic equalization, a soft limiter, thermal and RMS protection, and Bass Motion Control excursion management help maintain performance under demanding conditions. The enclosure is built from Baltic birch plywood and finished with a scratch-resistant polyurea coating for durability in portable and installed use. Side handles support transport, and the M20 pole mount adds practical system flexibility. As a complement to 8" or 10" loudspeakers, the SUB 708-AS MK3 is a strong choice for small to mid-sized venues and mobile sound applications.
