Speaker Cabinet Port Tube 1-1/2" ID x 4" L Flared
Speaker Cabinet Port Tube 1-1/2" ID x 4" L Flared is rated 4.25 out of 5 by 8.
Rated 5 out of 5 by from Recommended for Voxel mini-subUsed two of these glued together with SuperGlue in Paul Carmody's design. If you drill a 2.5 inch hole for this you may need to do what I did and use a little clear silicone adhesive to hold it in snug.

Rated 4 out of 5 by from not exactly as describedthis port has an ID of 1-9/16" and is 4-3/8" long. you need to deduct 1/4" from all port calculations, because of the length of the flare at the end of the port. A 2-9/16" hole cut will firmly seat this port in the box. The fins *do not* break off easily. You should use gasket tape, plus sealant to seat this in place. If you use a woofer over 5" in diameter, you should use 2 of these ports, glueing them end to end (once the correct length is determined) so that flares are at both ends to take out any port speed noise. If you use two ports back-to-back, remember to deduct 1/2" from all port calculations.Why is this important? when using a small box volume, minor changes in port length/diameter can make large differences in performance. In a box volume of less than 0.5 cu ft, the difference in posted ID of 1-1/2" and actual 1-9/16", can make a difference of over 1" in port length needed (length increases as ID increases).hope this helps!

Rated 5 out of 5 by from Easiest port tube to use!Use your hole saw to drill a 2.5" hole...you're done. This thing will pop right in.Sturdy plastic and long length are two great features. Easy to cut down to tuned length.Finally, a cost effective and efficient port tube that doesn't require a bunch of fiddling. A hard to mount port tube is the last thing you want to deal with at the final stage of the building process; you need something easy and quick so you can listen to what you just wasted endless hours designing and machining!

Rated 5 out of 5 by from My favorite 1.5" portHere's some tips to get the best out of this product. This port requires a 2-9/16" hole. If you get it accurate enough, it will press in and stay well without breaking the fins or needing epoxy.If you'd like to use this port with a 6 or 7" woofer, you can avoid the port speed turbulence issues by using 2 ports glued end to end so that you have a flare on the inside. Of course you will have to cut each half to length and glue or tape it together.With 5-1/2" or smaller woofers, no need to worry about port turbulence.
