1/3
Independent shopping perspective
The Korena take
Two-ply oil-filled 22-inch bass drum head in black. Built for a short, thuddy kick with minimal ring — a studio and heavy-music staple.
Strong match
Who this is for
- Rock and metal drummers wanting a deep, dead kick thump
- Studio sessions where a controlled kick saves mixing time
- Players who want damping without stuffing the shell
Consider the trade-offs
When to look elsewhere
- Jazz or orchestral players needing an open, sustaining kick
- 20-inch or 24-inch bass drums
- Anyone wanting bright attack and stick definition
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
Black film
Slightly darker and warmer than the clear version of the same head, and it hides beater marks.
Detail 03
22 in. diameter
Standard rock bass drum size. Measure the shell, not the hoop, before ordering.
Detail 04
Batter head
Goes on the pedal side. Your front head with the port hole stays as is.
Detail 05
Heavier film
Takes hard beater hits well and lasts longer than a single-ply head under heavy playing.
Final check
Know before you order
- 01Head only — no impact patch, drum key, or front head included
- 02Two-ply heads feel stiffer under the beater than single-ply; pedal response changes
- 03Tune low and even; over-tightening a hydraulic head kills the low end
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How dry does this actually sound?
Very. The oil layer removes most sustain, leaving a short low thump. Little to no internal muffling is usually needed.
02Does black film sound different from clear?
Slightly. The added coloring darkens the tone a touch. The bigger factor is the two-ply hydraulic construction.
03Will this fit my 20-inch kick?
No. This is a 22-inch head for 22-inch bass drums. Check your shell diameter before ordering.
04Do I need a beater patch with it?
Yes, recommended. A patch keeps the beater from wearing a hole in the film and extends head life.
