Overview

Celestion G12H-150 Redback 12" Guitar Speaker 16 ohm

The G12H-150 Redback was designed for guitarists who demand massive power handling without sacrificing tone. With a huge 150W rating, a heavy-duty 2" voice coil, and the largest G12 magnet, it delivers classic Celestion character while standing up to the full force of a 100-watt head on its own. This speaker shows you can have both power and tone in one package. Engineered with tight, controlled lows, a detailed midrange, and smooth treble, the Redback offers balance, responsiveness, and easy playability with serious muscle. In lower power combos, it produces rich, clean tones and works beautifully with pedals. If you want to downsize your cabinet, a single Redback paired with a 100W head still delivers massive, thunderous tone.
