Celestion AN2775 20W 8ohm Compact Full Range

Descrizione

Celestion - AN2775 20W 8ohm - Compact Full Range Loudspeaker - NeodimioFeatures- Compact and lightweight, full-range neodymium loudspeakers- Advanced Finite Element Analysis techniques used for acoustic, mechanical and electromagnetic modelling- Ideal for applications such as portable line arrays where actively controlled wavefront (beam steering) is used- Delivers wider dispersion to higher frequencies than many equivalent compact, full-range drivers on the market- Chassis purpose-designed for maximum free air movement, with square mounting frame to facilitate close coupling of multiple units- Stiff and light aluminium cone remains rigid to higher frequencies, delivering a smoother response in the critical listening band- Half roll elastomer surround provides damping for unwanted resonances and sustained centring control at extremes of excursion- Designed to be weather resistant for outdoor applicationsGeneral SpecificationsNominal diameter: 70mm/2.75inPower rating(1): 20WrmsNominal impedance: 8ohmSensitivity(2): 84dBFrequency range: 160Hz-20kHzVoice coil diameter: 20mm/0.75inChassis type: Glass reinforced ABSMagnet type: NeodymiumVoice coil material: Round CopperFormer material: PolyimideCone material: AluminiumSurround material: ElastomerXmax(3): 1.5mm/0.06inGap depth: 3mm/0.12inVoice coil winding width: 6mm/0.24inSmall Signal ParametersD: 60mm/2.36inSd: 28.27cm2/4.38in2Fs: 150HzMms: 1.83g/0.06ozQms: 12.21Qes: 1.67Qts: 1.47Re: 5.20ohmVas: 0.58lt/0.020ft3BI: 2.43TmCms: 0.51mm/NMounting InformationOverall depth: 45mm/1.8inOverall size: 71.3 x 71.3mm/2.8in x 2.8inCut-out diameter: 66.1mm/2.6inFitting: 4 x M4 holesMounting PCD range: Ø82mm/3.2inUnit weight: 100g/3.53ozNote(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)Measured on axis at 1W, 1m in 2pi anechoic environment.(3)Xmax derived from: (voice coil winding width-gap depth)/2.
