Product Details

Precision Port 2" 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.

The 2" model now comes with starter holes on the rear of the mounting flange, allowing the user to decide whether to use 3 mounting holes, 4 mounting holes, or none at all! All you need is a standard twist-drill to make your custom mounting decision. The central tube can be cut to any desired length, with a maximum overall port length of 11". Once the pieces are cut, the system can be permanently bonded with ABS pipe cement. Dimensions: • 5-1/4" outside flare outer diameter • 4-1/4" cutout • 4-3/16" inside flare outer diameter. Also available in 3", 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.

Precision Port 2" Flared Speaker Cabinet Port Tube Kit
Precision Port 2" Flared Speaker Cabinet Port Tube Kit is rated 4.7059 out of 5 by 17.
Rated 5 out of 5 by from My "go-to" portThis port looks and sounds great. For some reason the equation that comes with the paperwork is impossible, but using BassBox 6 pro I got the length I needed and it sounds great. I would suggest using screws and gasket tape as well.

Rated 5 out of 5 by from Great port tube!solid construction, high quality ABS. Included a formula sheet to calculate the proper port length. I'd recommend using the formula sheet over one of the free speaker design programs such as winISD.

Rated 5 out of 5 by from Excellent Product!These are some very well built ports. A must to have the flares to reduce port noise. Excellent quality, a bit pricey, but worth every penny.

Rated 5 out of 5 by from It's a flared portIt's a flared port. That pretty much sums it up. Just as a warning, it may be hard to install it since there's no real way to attach the port outside of glue. And the middle tube feels very thin. OK sure, for the materials you definitely get nearly no value for the money, but it's a flared port! It really does make a huge difference in speaker design. In my opinion, it should be illegal not to use one.

Rated 5 out of 5 by from Excellent product for the price!!Once you calculate the correct square dimensions of your speaker box or cabinet. (There are websites that can help you with calculations) Remember to measure twice and cut once. I have seen similar products for twice the price, but this tube kit has great smooth sound when it is correctly installed. I will purchase another one soon.

Precision Port 2" Flared Speaker Cabinet Port Tube Kit

When calculating the enclosure volume, should I subtract the volume of the port tube?

Asked by: ZackWillie
Port and driver displacements can be considered in the overall volume of the enclosure. In most cases it is not enough to make any real difference, but it is application specific.

Hello, I plan on using one of these in a single cube enclosure for two Dayton Audio 6 1/2" classic 4 ohm woofers as part of a boombox project and I was wondering, how many inches from the enclosures internal wall should the port be? Thanks!

Asked by: mustardgas1
A general rule of thumb is to keep the opening of the port as far away from walls as it is in diameter, so in this case 2" would be a safe number.

Is there an easy way to put a 90 degree bend in this port? Will it work with PVC fitting sold in stores like Home Depot? Reason being, it will be too close to the rear of the enclosure for the length I need.

Asked by: Leesonic
I have seen standard PVC elbows used with these ports before but they required a bit of fabricating since they are not a direct fit.

This is dumb but 1st question:how long is this? I just want to be sure before i buy. Im building a 1.5cu ft box and i want it at 33hz. I used the calculator but how long does it need to be one end of a flare to the other end of the other flare

Asked by: Jake421
With dual flares the overall length will only need to be 4-1/4".

What type of glue do you recommend to glue the port to MDF?

Asked by: TomAGardner
Gorilla Glue or any two-part epoxy will work well for this application. We generally recommend drilling out the screw holes marked on the back side of the flare mounting flange for the best attachment method.

How short in length can this port be adjusted to?

Asked by: NewB
The shortest this port could be cut to is roughly 3" which is essentially just attaching the two flares together.
