PRECISION TRANSDUCERS2006the rules of sound

Established in 1949, RCF has prided itself on carrying out the designand production of its own products.We have always preferred to design and construct completely all ourown components.Many years dedicated to studying and building audio transducershave resulted in some notable milestones. RCF was the first companyin Europe to have a high level Research Centre studying loudspeakers,horns and compression drivers.There are many different ingredients that go into creating qualityproducts and systems. These include computer aided simulationsoftware to assist the understanding of transducer behaviour andthe relationship of dynamics and transient response. RCF utilisesmany state of the art software to identify magnetic circuits, voicecoil dynamics, suspension linearity, horn dispersion simulation, etc.,however it is the vast technical and practical experience that ourResearch and Engineering team posses that ensures the quality ofour products plus placing RCF as the market leaders in transducerdevelopment.RCF The Transducer Innovators The RCF loudspeakerline incorporates a vast range of transducers covering the entireaudio spectrum. We design our transducers to optimise the relationshipbetween the purity of sound, combining the absence of distortion andthe ability to withstand high power levels over a long period of time.RCF develops advanced transducer technology including the applicationof high-tech materials such as carbon fibre, pure titanium, Kevlar¤and Mylar¤ hybrids. With over 50 years of design and manufacturingexperience in the market, RCF have been instrumental in technologicalinventions such as: carbon fibre cone moulding , double siliconspiders , inside/outside voice coil windings to edge wound voicecoil manufacturing and pure titanium diaphragm forming. Our latestdevelopments have resulted in designing state of the art neodymiummagnetic circuits and ground breaking direct drive voice coilassemblies.1

LOW FREQUENCYNEODYMIUMTRANSDUCERSFor decades RCF professional woofers haverepresented the ultimate performance,the highest power handling and themost advanced technology.Thanks to high energy magneticdesigns, complex cooling systemsand specifically developed newtechnologies, our neodymiumtransducers place themselvesat the same, unsurpassed level.SEALEDMIDRANGE TRANSDUCERSRCF has developed two exceptional, sealed, midrange neodymiumdesigns. This innovative solution offer many advantages comparedto traditional midranges designs:- thanks to a massive neodymium magnetic circuit, sensitivityis up to 4 dB higher than traditional designs;- the optimally tuned rear chamber is sealed and doesn’t requirethe typical back wooden chamber;- the aluminum basket, in direct contact to the magnetic circuit,provides the best cooling ever found in a midrange transducer.2

INSIDE/OUTSIDEVOICE COILSRCF has developed a unique voice coil, combining the advantagesof inside/outside technology to the superior quality of polyimideimidematerials (wire resins and formers resins).The inside/outside coil offers many advantages:- the dissipation surface is doubled;- the adhesion area to the Former is doubled;- during thermal expansion the Former is squeezed betweeninside and outside layers offering the best mechanical resistance.Our inside/outside formers are made from polyimide-imidefibreglass and the area between the coil and the cone is a triplelayer of Nomex - fibreglass - Nomex for maximum stiffness andaccurate sound transfer.COMPLEXCOOLING SYSTEMSIn our complex cooling designs individual components cometogether to create an ideal ventilation system. Commencing withthe design of the basket, RCF has focused on providing finnedcooling channels while optimising the surface area available tothe front magnetic plate to dissipate heat efficiently.The dust cap and the sealed spiders function as an air pumpexpelling hot air and drawing in cool air every time the coneassembly moves. Many openings are situated directly on thetransducer s side and on the rear plate.3

LOW FREQUENCYTRANSDUCERSRCF was the first manufacturerintroducing many of the innovationsthat are now recognised standardin professional transducers,pioneering new solutions, frominside-outside voice coils todual spider silicon dampeddesigns. Our range, includingseveral industry milestones, isable to provide innovative toolsand solutions for the mostdemanding speakermanufacturers.MAGNETICCIRCUITS DESIGNSRCF R&D set out to develop magnetic circuits capable of deliveringthe highest, balanced level of performance in three specificareas; maintenance of a consistent, high integrity magnetic flux,distortion lowering design techniques and efficient integrationof the magnetic circuit design within the overall design of theloudspeaker cooling system. Our transducers features a fullyoptimized magnetic circuit highlighted by a flux maximizingdesign and a rear plate that provides the lightest possibleweight and highest flux efficiency. The design is optimized togenerate the minimum amount of flux modulation in the magneticassembly during typical voice coil movement within the gap.18

DUALSILICON SPIDERSRCF original dual silicone sealed spider design offers manyadvantages:- the two spiders offers double resistance to fatigue;- the silicon between the cloth layers, being a very high memorymaterial, provides the best shape stability to the spiders;- the system, being sealed, functions as an air pump expellinghot air and drawing in cool air every time the cone assemblymoves.RCF dual silicon sealed spider design provides to our transducerscooler operating conditions and optimised power compression.PROGRESSIVE SPACEDDEMODULATION RINGSOur top level low frequency transducers feature RCF uniquespaced gap demodulation technology designed to dramaticallylower distortion artifacts within the loudspeaker s operatingfrequency band. This technology assists in progressively brakingthe voice coil as it reaches its maximum excursion point. Thisbraking effect provides a much quieter, smoother transition forthe moving mass as it reaches its maximum excursion limits.19

HIGH FREQUENCYNEODYMIUMTRANSDUCERSEvery detail is under our control, fromtitanium forming and voice coilwinding to phase plugs machiningand final assembly. Lightweightand powerful, our neodymiumdrivers are a reference inperformance and reliability.DIRECT DRIVEVOICE COIL ASSEMBLIESThe top of the former is bent and bonded directly to the edge ofthe titanium diaphragm resulting in a Direct Drive configuration.Direct Drive guarantees optimal transfer of energy between thevoice coil and the dome assembly, providing smoother, extendedfrequency response beyond 10 KHz, reducing break up modesand lowering distortion. This assembly delivers high powerhandling along with excellent mechanical and thermal propertiesthat make RCF neodymium compression drivers robust andreliable.68

DIAPHRAGMASSEMBLIESDiaphragms and suspensions are precision formed from ultra thin pure titanium. Suspensionsare based on an innovative design using progressive parabolic semi circles. The sectionsof the suspension offer a consistent suspension modulus with a variable, altering profile.This drastically reduces distortion eliminating resonance points and assists in controllingsuspension break-up modes. The rear magnetic plate where the diaphragm assembly islocated, possesses specially designed CNC machined ventilation slots that eliminatestanding waves, turbulence and distortion created by the movement of the suspension. Atthe point where the titanium suspension is bonded to the assembly ring, a special dampeningadhesive has been applied in order to further reduce and eliminate distortion creatingresonances. The diaphragm assembly has been designed with easy field service in mindas it can be removed and replaced within minutes.NEODYMIUMMAGNETIC CIRCUITSNeodymium magnetic circuit designs provide even higher magnetic field strength in thevoice coil gap than standard ceramic assemblies while dramatically lowering the overallweight of the device. Neodymium rare earth material also provides higher levels of force(BL) that increase control of the dome assembly’s moving mass. This leads to higherefficiency, better transient response and diminishes high frequency distortion modes.A thin copper ring is precision pressed on to the pole piece in order to modify and lowerthe inductance characteristics of the magnetic circuit and voice coil providing a controlledextension of the acoustic frequency response. RCF has provided cooling fins on the rearof the aluminum diaphragm assembly cover that creates a heat dissipating surface areafor the driver’s magnetic circuit. This assists in lowering circuit temperature, improvingthe driver’s power compression characteristics and increasing output. Specific attentionhas been paid to magnetic circuit polarization for optimum thermal immunity.69
