Speaker Cabinet Port Tube 4" ID x 4-3/8" L
Speaker Cabinet Port Tube 4" ID x 4-3/8" L is rated 4.5 out of 5 by 10.
Rated 4 out of 5 by from Nice Inexpensive Port Tube, but.......I like these and use these. I always keep a spare as they tend to crack easily, especially if the cut out is too small. Note to Parts Express: these will not insert into a 4" cut out, it needs to be at least a 1/16th to 1/8 inch larger than 4".

Rated 5 out of 5 by from Just what I needed.I build guitar and bass cabinets and this is just what I need as my box program has a 4 inch port tube selected for most of my boxes.I cut them to size with a coping saw and glue them into place with Polyseamseal clear adhesive caulk.Inexpensive and they work.

Speaker Cabinet Port Tube 4" ID x 4-3/8" L

I am building a cabinet for a bass guitar amp.  It will house a 15" speaker and be about 22" by 24".    My question is whether I should use one port tube or two, and should I use the 4" tube  or another size?
