CelestionBlues/Rock 4x12 Speaker Set
1/3
Independent shopping perspective
The Korena take
Four 12-inch 16-ohm ceramic speakers for loading a 4x12 cabinet. For players rebuilding or reconing a cab for classic blues and rock voicing.
Strong match
Who this is for
- Reloading an empty or tired 4x12 guitar cabinet
- Amps up to roughly 120 watts total across four speakers
- Players chasing a vintage-leaning midrange voice
Consider the trade-offs
When to look elsewhere
- Bass rigs — the 75Hz low limit cuts off the bottom
- Full-range PA or hi-fi use, given the 5kHz ceiling
- Anyone unwilling to solder and wire a speaker array
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
75-5000Hz range
A classic guitar speaker window. It rolls off harsh top end and does not reach bass-guitar lows.
Detail 03
100dB sensitivity
Loud for the wattage. The cab will feel louder than the 30W rating suggests at the same amp setting.
Detail 04
Ceramic magnet, 50 oz
Firmer and tighter than alnico, with more headroom before the speaker itself starts to compress.
Detail 05
1.75 inch voice coil
A smaller coil breaks up earlier and warmer, which is where the blues and rock voicing comes from.
Detail 06
85Hz resonance, 5.3 inch depth
Shallow enough for most closed-back 4x12s. Check clearance behind the baffle before ordering.
Final check
Know before you order
- 01No cabinet, wire, or connectors included — speakers only
- 02Measure the 11.1 inch cutout and 11.7 inch bolt circle against your baffle
- 03Wiring four 16-ohm speakers wrong will mismatch your amp's output impedance
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What impedance will my cabinet be?
Each speaker is 16 ohms. Series-parallel wiring of all four gives 16 ohms total, which suits most tube heads.
02How much power can the cabinet handle?
Each speaker is rated 30W, so a full set handles about 120W total when the load is shared evenly.
03Will these fit my existing 4x12?
Check the 11.1 inch cutout, 11.7 inch mounting circle, four mounting slots, and 5.3 inch depth against your baffle.
04Can I use these for bass guitar?
No. The response starts at 75Hz and the 30W rating is aimed at guitar. Bass will push them past their limits.
