Detail 01
25W power rating
This is the whole point and the main limit. Match to a small amp, or split power across multiple Greenbacks.

Sale
Independent shopping perspective
The Korena take
The 25W 12-inch Greenback in 8 ohm. A low-power speaker for players who want the speaker itself to compress and break up early.
Strong match
Who this is for
- Low-wattage amps where speaker breakup arrives before ear damage
- Adding grind to a clean-sounding 1x12 combo
- Multi-speaker cabs where power is split across drivers
Consider the trade-offs
When to look elsewhere
- Loud clean playing — it colors and compresses under load
- Amps over roughly 25 watts driving a single speaker
- Bass, keys or full-range 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
8 ohm nominal impedance
Runs alone off an 8 ohm tap. Two of these wired in series make 16 ohm, in parallel 4 ohm.
Detail 03
12 inch
Drops into standard 1x12, 2x12 and 4x12 baffles. Still confirm cutout and depth on your specific cab.
Detail 04
Green cone label
Cosmetic only. It identifies the model at a glance through an open-back cab.
Final check
Know before you order
- 01Speaker only — no connecting wire, screws, gasket or terminals
- 02Confirm your amp has an 8 ohm output, or wire multiples to suit
- 03Measure baffle cutout and rear depth clearance before ordering
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will a 50W head blow this speaker?
A single one, likely yes. It is rated 25W. Use a smaller amp, or spread a bigger amp across several of them.
02How many do I need for a 4x12?
Four. Wired together they handle 100W total, which is why Greenbacks are commonly used in fours rather than alone.
03Can I mix this with other speakers in one cab?
Yes, but the lower-rated speaker takes the same voltage as the others, so it becomes the weak point. Watch total impedance too.
04Is this 8 or 16 ohm?
This listing is 8 ohm.
