Bass-reflex port tubes for DIY speakers

This set of four port tubes is designed for builders constructing vented loudspeaker enclosures who need a finished, professional-looking bass-reflex opening. Each tube fits a 44 mm mounting hole and adds 66 mm of total length to the cabinet interior. They are sold new and ready for immediate installation.

Flared profile reduces port turbulence

The flared ends with a 49 mm maximum diameter and 39 mm minimum diameter smooth airflow at the entrance and exit, lowering unwanted noise and distortion compared with straight tubes. Standard mounting holes simplify alignment and fastening during cabinet assembly.

Mounting diameter 44 mm determines fit

The critical dimension is the 44 mm mounting diameter; verify your enclosure cut-out matches this size before purchase. Total length of 66 mm sets the internal port depth, so ensure the cabinet volume accommodates it.

Questions about this item

Will the 44 mm mounting diameter need any replacement parts later?

The tubes are solid plastic with no moving parts, so no maintenance or replacement components are required once installed.

What dimension limits how many tubes fit in a cabinet?

Each tube has a 66 mm total length and a 49 mm maximum diameter, which set the space needed per port.

Do the tubes generate heat or noise when the subwoofer runs all day?

Being passive vents, they produce no heat or electrical noise; only airflow turbulence could occur at very high output.
