A Celestion Classic Reissued to Celebrate a Legend
The original G12H made history with the first great rock tones thanks to its heavier H magnet. The G12H Anniversary version pays tribute to this iconic model by recreating its incisive grain, low-end sustain, and clarity in the highs. It delivers the sonic authority that built Celestion's reputation in guitar amplification.
Who Is It For and What Are Its Uses?
Ideal for classic rock, blues-rock, and vintage hard rock guitarists, this speaker suits those seeking a tight clean tone with plenty of projection and textured crunch. In a 1x12 cabinet, it adds presence and punch to a combo; in 2x12 or 4x12 setups, it provides a wide soundstage, clear chords, and lead lines that cut through without harshness.
Sound Character and Daily Strengths

Its high sensitivity and ceramic magnet deliver immediate impact, useful both in rehearsals and on stage, with excellent pick attack response.
Tonal Balance
Firm, muscular bass supports present low mids, while the highs remain bright yet natural, producing a sound that cuts through the mix without becoming harsh.
