Detail 01
30W power rating
It breaks up early, which is the point. Match it to a low-wattage amp or wire multiple speakers to share the load.

CelestionG12H Anniversary 30W, 12" Guitar Speaker 16 Ohm
Independent shopping perspective
The Korena take
A 12-inch guitar speaker with a 50oz magnet and 30W rating, built for players who want early breakup and a strong low-mid push.
Strong match
Who this is for
- Low-wattage tube combos where speaker breakup is part of the sound
- Adding weight and thump to a thin-sounding 1x12
- Recording rigs cranked to speaker distortion at manageable volume
Consider the trade-offs
When to look elsewhere
- High-power amps — 30W is easy to exceed with a 50W head
- Players who want clean headroom at stage volume
- Bass, keys or full-range PA use
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
100dB sensitivity
Loud for the wattage. It will sound noticeably louder than a 97dB speaker fed the same power.
Detail 03
75Hz-5000Hz range
Reaches lower than most 12-inch guitar speakers and cuts off top end early, giving a thick rather than bright character.
Detail 04
50oz ceramic magnet
Heavy magnet tightens low end and firms up response compared to lighter-magnet speakers of the same size.
Detail 05
5.3-inch overall depth
Deeper than average. Check clearance in shallow combos before you order.
Detail 06
1.75-inch voice coil
Larger than vintage-style 1-inch coils, so it handles its rating with more thermal margin.
Final check
Know before you order
- 01Verify the impedance you need before ordering — it comes in more than one value
- 02Bare driver only. No mounting hardware, wire or connectors included
- 03Check cabinet depth against 5.3 inches and the 11.1-inch cutout
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will 30W handle my 50-watt head?
Not on its own. Either run a lower-wattage amp or use two speakers in a cabinet so the load is split between them.
02What impedance should I get?
Match your amp's output. A single speaker should equal the amp's rated load; multiple speakers change the total depending on wiring.
03How is it different from a lighter-magnet 12?
The 50oz magnet and 75Hz low reach give more low-end weight and a firmer feel than smaller-magnet speakers.
04Will it fit my combo?
It needs an 11.1-inch cutout, an 11.7-inch bolt circle with four slots, and 5.3 inches of depth behind the baffle.
