The RCF J8 features a line source satellite module with eight 2” full-range drivers paired with a high-powered 12” woofer in a bass reflex enclosure. All powered by on-board 1400 W Class D amplification. The EVOX J Series maintains a similar footprint to the original EVOX systems, now in a portable composite enclosure. The system offers stunning sound performance with crystal-clear vocal reproduction and unparalleled musical response.
POWERFUL CLASS D AMPLIFIER
RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. D-Line amplifiers deliver ultra-fast attack, realistic transient response and impressive audio performance. The amplifier features a solid mechanical aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. The EVOX J amplifiers present SMPS power supply section in order to produce maximum output and minimum transportation weight.
THE TRANSDUCERS INNOVATORS
The RCF loudspeaker line incorporates a vast range of transducers covering the entire audio spectrum. We design our transducers to optimise the relationship between the purity of sound, combining the absence of distortion and the ability to withstand high power levels over a long period of time. RCF develops advanced transducer technology including the application of high-tech materials such as Neodymium, Carbon Fibre, Pure Titanium, Kevlar, Kapton and Mylar hybrids. With over 60 years of design and manufacturing experience in the market, RCF has been instrumental in technological inventions such as: carbon fibre cone moulding, double silicon spiders, inside/outside voice coil windings to edge wound voice coil manufacturing and pure titanium diaphragm forming. Our latest developments have resulted in designing state of the art neodymium magnetic circuits, radically new voice coil ventilation systems and ground breaking direct drive voice coil assemblies.
POWER HANDLING
At the core of RCF’s new transducer designs, significant amounts of time and resources were spent in terms of material science, design topology research and power testing in order to develop products with high structural strength, optimal thermal characteristics and the best possible power handling. RCF Precision engineers have developed a composite polyimide-imide former material capable of withstanding peak temperatures in excess of 380°C, well beyond the thermal requirements of modern professional audio systems. By combining this material with special adhesives, our inside-outside voice coil technology, dual silicone spiders, dual forced hyperventilation and cones based on a special fibre doping and treatment, the new RCF family of products features the industry’s most robust and reliable transducers.
NEW FERRITE MATERIAL: HIGH POWER, LOW WEIGHT MAGNETIC CIRCUIT DESIGNS
RCF Precision engineers have developed a new ferrite magnet capable of delivering higher flux in a new, minimum weight design. Thanks to this new technology, all new RCF Precision ferrite products present the minimum weight for comparable performances. New specific magnet sizes and moulds have been developed to optimise the new design performances. RCF Precision set out to develop a magnetic circuit topology capable of delivering the highest, balanced level of performance in three specific areas: maintenance of a consistent, high integrity magnetic flux gap, distortion lowering design techniques and efficient integration of the magnetic circuit in a minimum weight design. The T-pole design is optimised to generate the minimum amount of flux modulation in the magnetic assembly during typical voice coil movement within the gap.
DUAL FORCED HYPERVENTING SYSTEMS
In our complex cooling designs individual components come together to create an ideal ventilation system. Commencing with the design of the basket, RCF Precision has focused on providing finned cooling channels while optimising the surface area available in order for the front magnetic plate to dissipate heat efficiently. When assembled and placed on the basket, the front plate, ceramic core and the rear plate form part of the ventilation system that is highlighted by cooling slots precision machined through all three components. RCF Precision’s unique double silicone sealed spider design functions as an air pump expelling hot air and drawing in cool air every time the cone assembly moves. This system provides cooler operating conditions and optimal power compression. The perfect balance of noise control and quantity of the air venting the inner side of the voice coil is guarantee from a diffractor placed at the centre of the pole piece.
