I bought two of these eleven years ago, and used one right away. I just used the second and was thinking it was about time to write a review. The main reason I purchased this was to eliminate port noise on a box that was converted to a vented design. For that purpose the tube performed very very well. The only two drawbacks are: 1) You do need a decent flat surface area to mount the flange and then must avoid the speaker and inner walls, and 2) the port only supports Lv values up to 1134; (with a mechanical length of 1234;). For my second design, I needed it to be about an inch longer. Fortunately, I still had the 'cutoff' from the first design and was able to extend the port. (This critical dimension isn't even provided in the product description.) For a 'cut-to-length' product, it should be longer than what was provided. Other than the limitation on length, it's otherwise a good option for either custom enclosures or adding a port to an existing box.

Need longer extension. No compatible extensions or 90 degree elbows . 5 stars if 11 inche port is long enough for you.

Works great. I used a pair of these in a 34;Ball Park Boombox34; I built for my daughter's softball team. They are facing forward on a down firing sub and there were no huffing sounds when I had just the sub playing during sound tests. The bevel port end looks good with the curves of the box and fill the void between speakers nicely.
