Detail 01
Alnico magnet, 5 inch diameter
Alnico saturates earlier than ceramic under load, so the speaker starts compressing before the amp does.

Sale
Independent shopping perspective
The Korena take
A 50W alnico 12-inch in the 15-ohm version, weighing 9.3 lb. For players rewiring a cab around a low-wattage amp and wanting an alnico driver.
Strong match
Who this is for
- Low-wattage combos where the speaker is meant to compress
- Cabs wired for 16-ohm amp outputs
- Replacing a ceramic driver with an alnico magnet
Consider the trade-offs
When to look elsewhere
- Amps over 50 watts driving a single speaker
- Anyone needing an 8-ohm load out of the box
- Builds where 9.3 lb of magnet is too heavy
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
50W rating with 100dB sensitivity
Lower power handling but high output, so it gets loud on very little amp power.
Detail 03
15 ohm nominal impedance
Intended for amps with a 16-ohm tap. Two in parallel land at 7.5 ohms, close enough for an 8-ohm output.
Detail 04
75-5000Hz frequency range
Both ends are narrow by hi-fi standards. That restricted top end is what keeps distortion smooth rather than fizzy.
Detail 05
6.5 inch overall depth
Deeper than many drivers. Check clearance behind the baffle in shallow combos before ordering.
Detail 06
11.1 inch cutout, 11.7 inch bolt circle, 4 slots
Standard 12-inch mounting, so it fits baffles cut for other 12s with a four-bolt pattern.
Final check
Know before you order
- 01Confirm your amp has a 16-ohm output or that your cab wiring lands near it.
- 02Measure depth behind the baffle; 6.5 inches is deeper than average.
- 03A 50W rating means one of these will not cover a 100W head alone.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I run a 15-ohm speaker on a 16-ohm output?
Yes. A 15-ohm nominal load on a 16-ohm tap is well within normal tolerance for a tube output transformer, and speaker impedance swings far more than that with frequency anyway.
02What is the difference between alnico and ceramic here?
Alnico magnets lose grip sooner as power goes up, so the speaker compresses and softens attack earlier. Ceramic stays stiffer and cleaner at the same volume.
03Will 50 watts handle my 50W amp?
It matches on paper, which leaves no margin. Players running a 50W amp hard usually want the speaker rating above the amp, or the load split across two drivers.
04How heavy is it?
9.3 pounds, or 4.2 kg. That is on the heavier side for a single 12, mostly because of the 5-inch alnico magnet structure.
