What matters in use
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 01
Fits a mic inside the drum and lets air escape. Big enough for most kick mics, tight for large-diaphragm bodies.
Detail 02
Reinforces the cut edge so the head does not tear outward from the opening under playing tension.
Detail 03
Blends into white or coated front heads. It will stand out against a clear or black head.
Detail 04
The front head, not the one you hit. Porting changes sustain: shorter decay, more attack, easier to mic.
Detail 05
Cheap enough to buy alongside a new front head rather than risk cutting an old one twice.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is the reinforcement ring only. You cut the opening yourself, then apply the ring around it.
The front resonant head, not the batter head you strike.
Most standard kick mics pass through a 5-inch opening. Very large bodies or shock mounts may not.
The ring can come off, but the hole you cut in the head is permanent.
