Frequently Asked Questions
RCF improved the driver design in the MK3, resulting in tighter, more controlled bass response and slightly improved headroom without distortion.
While powerful, the SUB 705-AS MK3 can be used in smaller venues by adjusting gain and crossover settings, but it's best suited for spaces needing significant low-end reinforcement.
