Powerful Class-D Amplifier
RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. RCF amplifiers deliver an ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure, which not only stabilizes the amplifier during transportation, but also helps the fan-less heat dissipation. The amplifier presents an SMPS power supply section to produce maximum output and minimum weight.
Innovative Transducers
RCF specializes in developing advanced transducer technology, including the application of high-tech materials such as Neodymium, Carbon Fiber, Pure Titanium, Kevlar, Kapton, and Mylar hybrids. With over 70 years of design and manufacturing experience in the market, RCF has been instrumental in technological inventions, such as carbon fiber cone molding, double silicon spiders, inside/outside voice coil windings to edge wound voice coil manufacturing, and pure titanium diaphragm forming. Latest developments have resulted in designing state of the art neodymium magnetic circuits, radically new voice coil ventilation systems, and groundbreaking direct-drive voice coil assemblies.
Legendary Subwoofers
RCF subwoofers are the first choice of many sound engineers thanks to the very-high SPL levels at very-low frequencies, small dimensions compared to the competitors, self-powered design, internal delay control, cardioid configuration options, and impressive size/weight to SPL output ratio. Your crowd will be able to live an engaging immersive experience.
Cabinet and Mechanics
The RCF cabinets are made of the best multi-ply hardwood coated with a textured black finish. The subs are stackable and lightweight for easy setup and tear down thanks to the ergonomic handles. Pole receptacles on top and side allow 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 transducer from dust.
