Detail 01
30W power rating (each)
Low headroom by design. A pair handles 60W total, so a loud amp can push them past their limit.

CelestionBlues/Rock 2x12 Speaker Set
Independent shopping perspective
The Korena take
A matched pair of 12-inch, 30W ceramic guitar speakers for loading or reloading a 2x12 cabinet. For players rewiring an existing cab.
Strong match
Who this is for
- Reloading a 2x12 cab that already fits 11.1-inch cutouts
- Low-wattage amps where you want the speaker working hard
- Builders wiring a pair to 4 or 16 ohms
Consider the trade-offs
When to look elsewhere
- High-power amps — 30W each means 60W total handling
- Bassists; the 75Hz low limit is guitar-range
- Anyone wanting a drop-in with no soldering or wiring
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
Very efficient. Gets loud on little power, so a small amp sounds bigger than its wattage suggests.
Detail 03
8 ohms nominal, per speaker
Two in parallel gives 4 ohms, two in series gives 16. Match your amp's output tap.
Detail 04
Ceramic magnet, 50oz
Heavier than a comparable alnico speaker. At 10.4lb each, a loaded 2x12 gains roughly 21lb.
Detail 05
5.3-inch overall depth
Measure your cab's internal clearance. Deep magnets can foul a shallow cab's back panel or bracing.
Detail 06
11.1-inch cutout, 11.7-inch mounting PCD, 4 slots
Check these against your baffle before ordering. Four slots won't line up with an eight-bolt baffle.
Final check
Know before you order
- 01No cabinet, wire, hardware or gaskets — speakers only
- 02You need soldering tools and a way to wire the pair
- 03Confirm your amp's minimum impedance before choosing series or parallel
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What impedance do I get if I wire both together?
Each is 8 ohms nominal. Wired in parallel you get 4 ohms; in series, 16 ohms. Pick the wiring that matches your amp's output.
02Can I run these with a 50-watt head?
The pair is rated 60W total, so a 50W head fits with little margin. Push a loud amp hard and you're at the limit.
03Will they fit my cabinet?
They need an 11.1-inch cutout, an 11.7-inch mounting circle with four bolt positions, and 5.3 inches of depth clearance. Measure before ordering.
04How much weight does this add to a cab?
10.4lb per speaker, about 21lb for the pair. Worth factoring in if you already carry the cab to gigs.
