About This Product
Building or modding a speaker box?
This is a universal bass reflex port tube, perfect for enclosures housing 12 to 18-inch speakers.
The important numbers: the opening hole diameter is 110mm (that's about 4.33 inches), and the tube length is 200mm (7.87 inches).
It's an open-box item, but in great shape.
The front outside diameter measures 128mm, and it tapers down to a tail outside diameter of 91mm.
This flare helps reduce port noise and lets air move smoothly.
Made in China, unbranded, but does the job.
If you're tuning a subwoofer box for deeper, louder bass, this vent tube is a key component.
Get that air moving right.
