Detail 01
Hydraulic construction
Two plies with a thin oil layer between them. The oil kills overtones, so the note is short and fat.

1/3
Independent shopping perspective
The Korena take
Blue 22 inch hydraulic bass drum batter head. For drummers who want a short, deep thud with damping built in.
Strong match
Who this is for
- 22 inch bass drums needing a controlled, punchy note
- Players who dislike stuffing pillows or blankets in the kick
- Loud styles where a long ringing kick gets lost
Consider the trade-offs
When to look elsewhere
- Drummers wanting an open, resonant, sustaining bass drum
- Bass drums that are not 22 inch
- Anyone after a bright, articulate attack with lots of overtone
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
22 inch
Matches a 22 inch bass drum shell. Measure the shell diameter, not the hoop or the old head's rim.
Detail 03
Two-ply film
Thicker and more durable than a single ply. Takes repeated beater impact better and stays in tune longer.
Detail 04
Blue film
The blue tint comes from the oil layer between plies. It is a visual marker of the design, not a coating.
Detail 05
Batter head
Goes on the beater side. The front head with the port hole is a separate purchase.
Final check
Know before you order
- 01Confirm your bass drum is 22 inch by measuring the shell diameter
- 02Front resonant head and any port hole are not included
- 03Built-in damping means you likely will not need internal muffling; remove pillows first and listen
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this need extra muffling?
Usually not. The oil layer already shortens the note. Start with no pillow inside and add damping only if you still hear ring.
02Which side does this go on?
The batter side, where the pedal beater strikes. It is not a front head.
03Will it fit a 20 or 24 inch kick?
No. This is cut for a 22 inch shell and will not seat correctly on other diameters.
04How durable is it?
Two plies of film give it more life under a beater than a single-ply head, especially with hard, frequent playing.
