150W Guitar Speaker Built for High-Power Applications

The Celestion G12H-150 Redback 8 Ohm is a 12-inch speaker crafted for guitarists who expect both extreme power handling and authentic tonal response. Rated at 150W RMS with 8 ohm impedance, it stands up to a 100-watt tube head without losing responsiveness or musicality. No longer must players compromise between high headroom and great tone. Within the pressed steel chassis, a supersized 2-inch voice coil and the heaviest magnet in the G12 family create a sound unmistakably Celestion.

Supersized Voice Coil and Heaviest G12 Magnet

What distinguishes this speaker is its 50 mm voice coil paired with a 50 oz (1.42 kg) ceramic magnet—the largest of any G12 model. This design achieves a tight, controlled low end, detailed mids, and a relaxed treble that smooths out harsh high-mids. Guitarists switching from Vintage 30s describe a thicker, more balanced sound with less upper-mid aggression.

Power Handling and Impedance for Any Amplifier Setup

Matching your amp's output to the right speaker is essential for both tone and reliability. With a 150W rating, the Redback delivers tremendous headroom and easily handles applications from low-powered combos up to full 100W stacks.

• Power Rating: 150 W RMS — lets a single speaker run a 100W head without risk of compression or distortion
• Nominal Impedance: 8 Ω — delivers a fuller, smoother voice than the 16 ohm version for nuanced tonal differences
• Sensitivity: 100 dB — ensures efficient conversion of amplifier output into sound

Frequency Response and Tonal Profile

Faithful reproduction of your guitar's range is crucial, and this model brings low-mid warmth and controlled highs across the spectrum.

• Covering everything from fundamental notes to overtones, the frequency range of 70–5000 Hz meets the needs of most guitarists.
• Resonance Frequency (Fs): 75 Hz — imparts a thick, Greenback-like low end character
• Magnet Type: Ceramic (Ferrite) — classic Celestion clarity enhanced by warm compression
