Description

Recreating an iconic Celestion design that helped define rock guitar tone starting in the 1960s, the Celestion Heritage G12H-55 12" guitar speaker delivers the thick body, authoritative low end and distinctive growl of the original low-resonance G12H. Its 55Hz resonance extends the speaker's low-end response for deep, powerful bass, while a substantial 50 oz ceramic magnet contributes the punch and presence that distinguished the G12H from its lighter-magnet counterparts. Rated at 30W with 100dB sensitivity, the G12H-55 combines vintage British character with enough efficiency to project clearly in single- and multi-speaker cabinets, while a 55Hz–5kHz frequency range keeps the response focused on the frequencies that matter most for guitar. Available in 8- and 16-ohm versions, the Heritage G12H-55 is a compelling choice for vintage-inspired builds, replacement cabinets and players chasing the weight, warmth and unmistakable character of classic Celestion tone.
