POWERFUL LOWS

RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, smaller dimensions compared to the competitors, self-powered design, and impressive size/weight to SPL output ratio. Your crowd will be able to live an engaging immersive musical experience.

CABINET & MECHANICS

The RCF cabinets are made of birch plywood coated with a textured black finish. The subs are stackable and light-weight, for easy set-up and tear down, thanks to the ergonomic handles. A pole receptacle allows the use of the box in various configurations. The powder coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducers from dust.
