Celestion - CF1840JD 1000W 8ohm - LF Die Cast Chassis Loudspeaker - FerriteAltoparlante da 18 con chassis in fusione d'alluminio. magnete in ferrite. bobina da 4. potenza 1200Watt. impedenza 8ohmCaratteristiche- 18 ferrite magnet. cast aluminium chassis LF driver delivering 1200Wrms (AES Standard) power handling and 98dB sensitivity- 4 high temperature. dual layer. Inside/Outside voice coil for higher efficiency. preventing sensitivity loss through thermal compression- FEA optimized magnet assembly and suspension deliver highly symmetrical cone movement. leading to exceptionally low harmonic distortion- Vented magnet assembly increases airflow to provide enhanced cooling- Twin demodulation rings reduce flux modulation. minimizing electromagnetic distortion- Double suspension and multi-roll surround provide exceptional linearity at extremes of cone excursionSpecifiche GeneraliNominal diameter: 457mm/18inPower rating(1): 1200WrmsNominal impedance: 8ohmSensitivity(2): 98dBFrequency range: 30-2500HzVoice coil diameter: 100mm/4inChassis type: Cast aluminiumMagnet type: FerriteMagnet weight: 3.18kg/112ozCoil material: Round copperFormer material: Glass fibreCone material: Kevlar loaded paperSurround material: Cloth-sealedSuspension: DoubleGap depth: 10mm/0.39inVoice coil winding width: 30mm/1.18inXmax(3): 10mm/0.39inParametri di Thiele-SmallD: 0.38m/14.96inFs: 44.2HzMms: 215.15g/7.59ozQms: 4.21Qes: 0.496Mmd: 185.145g/6.54ozQts: 0.444Re: 5.29ohmVas: 113.924BI: 24.758TmCms: 0.063mm/NRms: 13.653kg/sLe (at 1kHz): 0.96mHInformazioni di MontaggioOverall diameter: 460mm/18.11inOverall depth: 220.35mm/8.68inCut-out diameter: 414mm/16.3inMounting slot dimensions: 11mm x 7mm/0.43-0.28inNumber of mounting slots: 8Mounting PCD range: 441-432mm/17.36-17.01inUnit weight: 11.6kg/25.5lbNote(1)Tested for two hours using a continuous. band-limited pink noise signal as per AES standard.
