Precision Port 3" Flared Speaker Cabinet Port Tube Kit

The unique flared-end construction of the Precision Port™ system enables it to outperform any standard port tube on the market. Conventional tubes suffer from nasty turbulence at the entrance and exit of the port, producing unwanted noise and poor sound quality. The Precision Port™ system overcomes these problems and as a result can actually produce a gain of up to 3 dB in output!

Now you can experience good looks, low distortion, and superior overall sound quality thanks to the Precision Port™ system. Convenient front screw holes make this tube easier to install than others on the market. Create a port up to 17" long, then glue with ABS glue found at any hardware store. Installation instructions included. Dimensions: • 6-1/4" outside flare outer diameter • 5-1/4" cutout • 5-3/16" inside flare outer diameter. Also available in 2", 4", and 6" diameters. Proudly Made in the USA!

To calculate the proper port length for your cabinet and tuning frequency, use Precision Sound Products' Port Length Calculator.

Rated 5 out of 5 by from Fantastic productI bought this about two weeks ago, shipped and processed right away. Excellent quality! Definitely the place to get your audio needs

Rated 5 out of 5 by from Precision portsI been using precision ports in all my custom ported enclosures. I love the way the total box dimensions stay small unlike Slot porting. And plus they are just sexy when installed properly

Rated 5 out of 5 by from Knock out!This port is worth every penny. Easy to install, clear instructions, improved sound over your "regular" port.

Rated 3 out of 5 by from Almost Perfect, but not very classy looking.I am designing and constructing a beautiful pair of home speaker towers. This port system seemed to fit the bill so I ordered two sets. They are just fine; Good quality material etc. However, the 1/2" flange for the outside port piece is textured to look like an old guitar amp or something with a textured vinyl covering. I decided to adapt and use the inside flare which is only nice polished black plastic. The flair is identical. It just doesn't have the ugly additional flange for mounting purposes. I have now decide to down-fire the port and it will not be seen at all. Precision Ports has very few products. Perhaps they will develop some that you would want to see outside the practice-room in the future.

Rated 5 out of 5 by from Great PurchaseQuality of the port was solid. Instructions included on how to calculate port length for box tuning were clear and concise (to me). So glad I made the decision to go ported with my W10GTI...it really opened up the sub and made things so much louder! For anyone wondering, I got the 3-inch port and box was 1.8ft^3 and tuned to 28Hz and Sounds great! could not be happier. Shipping was a bit steep to Canada (cost more than the part itself)

Precision Port 3" Flared Speaker Cabinet Port Tube Kit

I am building a10inch sub boxe with separate chambers. Does the Precision Port 3" Flared Speaker Cabinet Port Tube Kit come with 2 flares or do I need to buy 2? My sub requires a 3 in diameter tube and 8 in length per sub. 

Asked by: Gotsta B Rad
the kit has 2 flares.

I am building a tower with 2 8" woofers, internal volume is 2.276 Ft³. I need a 12.23" x 3" port for 25 Hz. Is it the same to face the port to the front or the rear of the cabinet? Should I consider adjustments to compensate for possible phase problems?

Asked by: Jaime Diaz
Port placement will not matter as long as you allow for proper airflow around the port openings.

What is the outside diameter of the plastic tube portion on this?  The actual tube itself, not the flares or connecting sleeves.  Currently my internal bracing has 3.25" diameter holes.  Thank you.

Asked by: balane
The OD of the tube itself is 3-1/8".

I'm using this 3" port to replace the 3" diam. cardboard tube on JBL L-88's. I was going to use the same length, including the flares, as the original cardboard tube. Bad idea? I can only shorten the tube not lengthen it because of space limitations.

Asked by: yogacraig
If you make the overall flared port the same length as the original straight port the tuning will go up slightly, but only a few Hz. This should not negatively affect audible performance.

Does this kit come with at least a foot of port length? I need at least 11 inches of port...

Asked by: KRNAZNBOY
The main tube of this kit is 12" long total, with flares added the overall length is 18".

I'm working on a ~1 cu ft box for a 10" sub, and want it to be tuned to 32 hz.  That requires a 3" port with length of 15.3". If I went with 2 3" ports, would they both need to be 15.3" long? 

Asked by: Griesj81
If you wanted to add a second port, they would each need to be 34" long to achieve the same tuning frequency.
