Celestion G12K-100 12" 8 Ohm Guitar Speaker 100W
Celestion's very own monster of rock,  the G12K-100, makes full  use of the  heaviest G12 magnet to combine huge  power handling with  superb clarity across a wide frequency response. A massive bottom-end,  rock-hard midrange  and restrained top-end make this  the perfect  speaker to add thump and  grind to modern high-gain tones.
Loaded in 4x12s it delivers its famous  sledgehammer lows, as  favoured by  Slayer’s Kerry King, but it also often  finds use in small  boutique combos,  bringing a powerful mix of low-end  warmth and  mid-range attack.
