Celestion : T5820: 2.7″ 20W Full Range Speaker 8OHM

Compact and lightweight full-range neodymium loudspeakersAdvanced Finite Element Analysis techniques used for acoustic mechanical and electromagnetic modellingIdeal for applications such as portable line arrays where actively controlled wavefront (beam steering) is usedDelivers wider dispersion to higher frequencies than many equivalent compact full-range drivers on the marketChassis purpose-designed for maximum free air movement with square mounting frame to facilitate close coupling of multiple unitsStiff and light aluminium cone remains rigid to higher frequencies delivering a smoother response in the critical listening bandHalf roll elastomer surround provides damping for unwanted resonances and sustained centring control at extremes of excursionDesigned to be weather resistant for outdoor applicationsNominal diameter 2.75″/70mmPower rating 120WrmsNominal impedance 8?Sensitivity 284dBFrequency range 160Hz-20kHzVoice coil diameter 20mm/0.75inChassis type Glass reinforced ABSMagnet type NeodymiumCoil material Round CopperFormer material PolyimideCone material AluminiumSurround material ElastomerXmax3 1.5mm/0.06inGap depth 3mm/0.12inVoice coil winding width 6mm/0.24inVoice coil material Round CopperVoice coil former material PolyimideBandwidth 190Hz-20kHzMounting InformationOverall depth 1.8″/45mmOverall size 2.8″ x 2.8″/71.3 x 71.3mmCut-out diameter 2.6″/66.1mmFitting 4 x M4 holesMounting PCD range 3.2″/82mmUnit weight 100g/3.53oz
