DescrizioneCelestion - CDX20-3075 75W 8ohm - HF Compression Driver - FerriteFeatures- 2 exit, ferrite magnet, 3 voice coil compression driver provides 75Wrms (AES standard) power handling and 107dB sensitivity- Patented phase plug design method suppresses cavity resonances at higher frequencies- Titanium diaphragm, deep drawn to increase stiffness and reduce distortion- Lower compression ratio reduces air non-linearity and allows for higher maximum SPL- Rolled polyimide surround improves stiffness control, further lowering distortion- Curved coherent wavefront, optimised for horn loadingGeneral SpecificationsPower rating(1): 75WrmsContinuous power rating(2): 150WNominal impedance: 8ohmFrequency range: 500-18,000HzSensitivity(3): 107dBRecommended min. crossover (12dB/oct): 800HzVoice coil diameter: 75mm/3inVoice coil material. Edgewound copper clad aluminiumMagnet type: FerriteDiaphragm material: TitaniumSurround material: PolyimideMounting InformationWidth: 180mm/7.09inDepth: 71mm/2.8inWeight: 4.8kg/10.6lbFitting: Flange (4 x M6 holes on 10mm/4inch PCD)Throat exit: 50mm/2inNote(1)Tested for two hours on plane wave tube using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance.(2)Continuous Power Handling is defined as 3dB greater than the AES rating.(3)Measured on axis at 1W, 1m, using typical horn, in 2 anechoic environment.
