Help finding Aero port

[Halostryker]

I've never used Aero ports before because I can never find the right size. Well now I'm trying to build a ht sub box and I would prefer to use an Aero port for the way they look and because it's easier to build.

For my build the box is gonna have a gross volume of 1.11 cubic feet tuned to 29 hz.

The port will need to be 3 inch by 20 inch.

Where can I find a port this length? Thanks guys

You can buy the Precision Ports (aeroports) at Parts-Express. They sometimes have decent sales on them too, and come in a few sizes.

As for how to tune them, the Precision Port company has a calculator on their website where you enter box volume, tuning freq desired, and port size which than tells you needed length.

only problem with that is the maximum length they make their ports is 17".

my advice, buy their 3" flares and some 3" PVC pipe from Lowes and there you go.

just make sure the connection between the flares and the PVC is air tight!

3" PVC lol

If you want to make them a custom length, do not buy normal schedule 40 PVC...that stuff is too thick and the couplers won't fit. You need to find some thin-wall PVC like what is used in the normal aeroport kits.

I've thought about this but wasn't sure it would work thanks for clearing things up
