EvansOnyx 2-Ply Drum Head 20 in.
1/3
Independent shopping perspective
The Korena take
A 20 in. two-ply Onyx batter head. For drummers who hit hard and want a dark, short, low-overtone sound from a large drum.
Strong match
Who this is for
- Heavy hitters who dent thinner heads within weeks
- A 20 in. floor tom or 20 in. bass drum batter
- Drums that ring too long and need natural control
Consider the trade-offs
When to look elsewhere
- Players wanting an open, singing, long-decay tone
- Anyone needing a resonant or front bass head
- Drums measuring 18 or 22 in.
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
20 in.
Fits a 20 in. drum — commonly a 20 in. bass drum or a large floor tom. Measure the shell.
Detail 03
Batter head
The struck side. On a bass drum that is the pedal side, not the logo side facing the audience.
Detail 04
Onyx film
Opaque rather than clear, so you cannot see through it to check seating on the bearing edge.
Detail 05
One head per pack
A full bass drum change needs a front head too, sold separately.
Final check
Know before you order
- 01One head only — no front head, no muffling pillow, no drum key
- 02Confirm your shell is 20 in.; head size is drum diameter, not hoop width
- 03Bass drum use means pulling the pedal and hoop off to fit it
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Bass drum or floor tom?
Either, as long as the drum is 20 in. across. It is a batter head, so it goes on the struck side.
02Will I still need muffling?
Often less. Two plies already shorten decay and cut overtones, so you may only need light internal damping.
03Does it fit a 22 in. bass drum?
No. Heads are sized to drum diameter. A 22 in. drum needs a 22 in. head.
04How does it compare to a single-ply head?
Shorter sustain, darker tone, fewer overtones and far more durability. A single ply is more open and rings longer.
