Celestion FTR15-3070E 400W 8ohm LF Ferrite

Descrizione

Celestion - FTR15-3070E 400W 8ohm - LF Die Cast Chassis Loudspeaker - FerriteFeatures- 15 ferrite woofer provides 400Wrms power handling (AES Standard) and 97dB sensitivity- 3 high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression- FlexirolTM surround for greater excursion control- Low frequency response, down to 40Hz- Smart chassis design minimises acoustic distortion- Specially treated weather-resistant coneGeneral SpecificationsNominal diameter: 381mm/15inPower rating(1): 400WrmsContinuous power rating(2): 800WEIA power rating(3): 550WNominal impedance: 8ohmSensitivity(4): 97dBFrequency range: 40-4000HzVoice coil diameter: 75mm/3inChassis type: Cast aluminiumMagnet type: FerriteMagnet weight: 2.3kg/81ozCoil material: Round copperFormer material: Glass fibreCone material: Glass loaded paper with weather-resistant impregnationSurround material: Cloth-sealedSuspension: SingleXmax(5): 5.5mm/0.22inGap depth: 9mm/0.35inVoice coil winding width: 20mm/0.79inSmall Signal Parameters4D: 0.33m/8.38inFs: 45.3HzMms: 88.69g/3.13ozQms: 3.07Qes: 0.46Mmd: 74.54g/2.63ozQts: 0.40Re: 5.36ohmVas: 143.85lt/5.08ft3BI: 17.24TmCms: 0.14mm/NRms: 8.22kg/sLe (at 1kHz): 1.3mHMounting InformationOverall diameter: 385mm/15.16inOverall depth: 161mm/6.34inCut-out diameter: 351mm/13.82inMounting slot dimensions: 10mm x 7mm/0.39in x 0.27inNumber of mounting slots: 8Mounting PCD range: 365-375mm/14.37-14.76inUnit weight: 6.4kg/14.1lbNote(1)Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.(2)Continuous Power Handling is defined as 3dB greater than the AES rating.(3)Tested as per the EIA-426-A standard.(4)Measured on axis at 1W, 1m in 2pi anechoic environment.(5)Xmax derived from: (voice coil winding width-gap depth)/2.(6)Small signal parameters measured after unit subjected to pre-conditioning signal.
