The most powerful amplifier in its classRCF's improvements in transducer design make our woofers stronger and powerful, so the amplifier follows the evolution. With 2200W power, our Class-D amplifier is able to manage extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low heat loss. So energy-efficient that there's no need for a cooling fan - the amplifier is attached to a solid aluminum heat exchanger in the rear of the cabinet - with no moving parts.

The stereo input circuit with crossover features a new low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. RCF amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high-efficiency with minimum weight.

Tour-Ready WorkhorseThe RCF cabinets are made of high-quality multi-ply hardwood coated with a black polyurea finish. The subs are stackable and light-weight, for easy set-up and tear down, thanks to the ergonomic handles. A pole receptacle on top and side 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.
