RCF CX12N351 Coaxial

The CX12N351 is a top class coaxial design that provides an excellent frequency response linearity withvery low distortion. The CX12N351 is powered from an integrated high power neodymium magnetic structure that guarantee high dynamic and sensitivity for both components. The mid-bass section features a 3,5" inside-outside voice coil design that provides a very high power handling, especially in comparison to a standard 3" voice coil. Thanks to an integrated demodulation ring the mid-bass section gets a fastest time response and lower distortion. The compression driver use a 2.5" diaphragm with a 1.4" throat featuring several state of the art technologies. The diaphragm and suspension are formed from 0.05 mm thick pure titanium Features3.5-inch , fibreglass outside aluminum voice coil900 Watt continuous program power handling98.5 dB Sensitivity50 Hz - 3.0 kHz Frequency rangeDual-forced air ventilation for minimum power compressionM-roll surround and exponential cone geometryDemodulation ring2.5-inch Diaphragm, 1.4-inch Exit Throat/pure titanium compression driver180 Watt Continuous program power handlingFrequency range: 700Hz " 20kHzDirect Drive Voice Coil Assembly3-slot, optimised geometry phase plugAluminum rear coverCopper inductance ring for extended responseSpecificationsNominal Diameter: 35.5 / 1.4 mm/inchRated Impedance: 8 ΩProgram Power: 180 WPower Handling Capacity: 90 WSensitivity 1 W, 1 m: 110 dBFrequency Range: 700 - 20000 HzMinimun Impedance: 7.9 ΩVoice Coil Diameter: 63.7 / 2.5 mm/inchVoice Coil Material: Edgewound AluminumNumber of layers: 1 - OutsideDiaphragm Material: Pure TitaniumDiaphragm Design: DomeSuspension Material: Pure TitaniumSuspension design: ProgressiveBL factor: 10.4 T Ã?· mFlux density: 2.0 TPhase plug design: 3 slotPhase plug material: AluminiumMagentics: NeodymiumVoice Coil Demodulatuon: Copper ringResonance frequency: Fs - 58 HzDC resistance: Re - 5.8 ΩMechanical Factor: Qms - 5.4Electircal Factor: Qes - 0.21Total Factor: Qts - 0.20BL Factor: Bl - 25 T Ã?· mEffective Moving Mass: Mms - 62 gEquivalent Cas air load: Vas - 47 litersEffective piston area: Sd - 0.053 mÃ?²Max. linear excursion ( mathematical): Xmax - 5.5 mmVoice - coil inductance @ 1 kHz: Le1K - 1.5 mHHalf-space efficiency: Eff - 4.4%Net Weight: 5.9 / 13 kg/lbsShipping Weight: 6.7 / 14.7 kg/lbs
