Subwoofer Port size help!

[bs199sg]

Hey, I have a Pioneer 12" subwoofer, and I am not sure how big I need the air port on the back of it. The enclosure is LxWxH- (in inches) 15.25x10.625x15.75. The volume of the enclosure is 1.035ft^3. Please help, Right now I have a port of 3", and its seems to want a bigger hole. The sub is 800 watts and can go down to 20Hz.

You are about a cube to small to port it.

Waaaay too small of a box. 1.035 is just gross cubic feet, you barely have any airspace left because after accounting in how much space the port and subwoofer takes, you probably only have .8 cubic feet at most. Noloud4u is right, add another cubic feet there if you want any real progress with this. A bigger round port means you need to sacrifice more airspace to achieve a lower tuning because it'll have to be a lot longer. Big and long aeroports take up a lot of room in the box. As of now you are just suffocating your sub.

Thanks for the help. What size do you recommend the enclosure and port to be?
