Independent shopping perspective
The Korena take
A 2-inch black port ring that finishes a cut hole in a bass drum head. For drummers venting a resonant head cleanly.
Strong match
Who this is for
- Finishing a hole you cut in a resonant bass drum head
- Letting air escape to shorten bass drum sustain
- Matching black hardware and black drumheads
Consider the trade-offs
When to look elsewhere
- Passing a microphone through — 2 inches is too small
- Anyone who wants the ring to cut the hole for them
- Players who like a fully sealed, boomy resonant head
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 finish
Disappears on a black or ebony resonant head; it will stand out on a white or coated one.
Detail 03
Port ring, not a hole cutter
It trims and reinforces an existing hole so the mylar does not tear or fray at the edge.
Detail 04
Single ring
One head, one port. A second bass drum or a spare head needs another.
Detail 05
Under sixteen dollars
Cheap insurance against a torn head, which costs several times more to replace.
Final check
Know before you order
- 01The hole is not pre-cut — you cut it yourself first
- 02Nothing else included: no cutter, no template, no second ring
- 03Place it off-center, away from the head's center, to keep tone
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I mic through a 2-inch port?
No. A 2-inch opening vents air but will not clear a kick mic and clip. If you plan to mic inside the drum, you need a larger port.
02How do I cut the hole?
You need a separate hole cutter or heated cutting tool. Mark the position off-center first, then cut clean — the ring covers the edge, not a ragged tear.
03What does a port actually do?
It lets air escape, which shortens sustain and tightens the low end. A sealed resonant head stays boomier and rings longer.
04Will black look wrong on a white head?
It will read as a dark circle against white or coated heads. That is a look some drummers want; if you do not, match the ring to the head.
