Rated 3 out of 5 by from Delivered product does not match with the imageDelivered product does not match with the image in this website.The required hole cut and entire diameter of the port is different. So this port can not apply to my enclosure!!See the below photo, the part number is correct but different product!!

Rated 5 out of 5 by from High Quality Port TubeThis port tube appears to be made of high quality styrene, as I was able to cut to the required length with my 12" miter saw! As another reviewer stated, ensure the hole for this port tube is 1 and 3/8 inch in diameter and you should be able to press fit for a nice professional look when installed. Shipping was faster than expected.

Rated 5 out of 5 by from For such a basic thing it's greatOkay, a bass port is just a plastic cylinder but these seem to be be made very well and there are no unsightly seams. I drilled for a very snug fit and I used a rubber mallet to gently pound them in, this worked fine. They fit in such a way that they don't rest flush against the outside, but extend just slightly where the lip flares out.

Rated 5 out of 5 by from Perfect for small Yamaha speakersI added two of these to each in a set of Yamaha NS-6490's.  One just above the woofer situated between the tweeter, midrange, and woofer.  The second port was added above the tweeter and midrange so it is centered vertically with the first port. What a gigantic difference in bass response and sheer volume of the bass.  These have brought out the hidden full-bodied sound reproduction of these bookshelf speakers.  Adding a generous amount of well-placed acoustic dampening foam inside the cabinets makes for smoother bass as well.  My personal "like them rating" has moved up from OK to Very good (from a 5.0 to a 8.75).  A friend with a stock pair brought his over for a "A-B" comparison and after he switched back and forth between his and my modded set he said, "I can't believe this", then asked me, "What the xxxx did you do to yours?!", and  "Will you do that to mine?".  I also padded down the midrange with three 5 watt cement resistors in series, two 4 ohm & one 6 ohm, and padded down the tweeter with two 4 ohm 5 watt cement resistors in series.  This cured the midrange and treble heavy nature of this model. and the ports nicely took care of deficient bass.  Now they are very well spectrum balanced and truly impressive for their size.  I highly recommend these ports for improving smallish acoustic suspension (sealed enclosure) speakers.  If they have at least an 8" woofer I recommend using two per enclosure placed front firing.

Rated 5 out of 5 by from Thee things are great for the priceI've purchased maybe 12-15 of these ports and they are always consistent in quality. It should be stated in the description that you need to drill a 1 3/8" hole for these.

Speaker Cabinet Port Tube 1" ID x 4" L Flared

I have a small enclosure housing a 3" full range driver and only have about 4.5" of inside depth; does the specific length greatly affect the sound of can I just work with what I have and cut the port short to get better bass than if I just sealed it?

I intend to buy 6 of these and cut and join them in pairs to make double flared ports. Do you provide joining sleeves, else are you able to point me in the direction of the suitable parts or even the material and schedule of the pipe to source my own?

Asked by: Bergo27
Unfortunately we do not have any couplings for this type of application and these will not be a standard size for any other pipe couplings. You will either have to glue or tape the two ends together.

How would I calculate the length for a flared port? I understand a flared port can be shorter than a non-flared, but by how much?

Asked by: Geoffrey
Flared ports need to be longer then their un-flared cousins. Adding 1/2 the length of the flare section of the port to the non-flared section of port will get you very close to the total port length.As you increase the cross-sectional area of a port you need to make it longer if you want tuning frequency to remain fixed.
