LOW FREQUENCYNEODYMIUM<strong>TRANSDUCERS</strong>For 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 <strong>TRANSDUCERS</strong>RCF 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
