Celestion – K12H-200TC 200W 8ohm – Twin Cone
Altoparlante doppio cono da 12′ con chassis in acciaio stampato, magnete in ferrite, bobina da 2′, potenza 200Watt, impedenza 8ohm
Caratteristiche
– 12′ twin cone drive unit with extended high frequency response
– 2′ high temperature copper voice coil for increased reliability and 200Wrms (AES standard) power handling
– Optimised cone neck/voice coil assembly for increased strength, minimising high frequency distortion and improving sound quality
– Secondary cone terminated by pressure formed cloth dust cap for enhanced mid-band clarity
– High efficiency magnet structure design delivers improved sensitivity
– Double roll surround for greater excursion control and smooth frequency response
