My design calls for a 6" diameter PVC aeroport. I can't find anything that size anywhere. Can I use two 3" ports instead of one 6" port?

What are the final goals? ie: Net volume and tuning?

Tuned to 32 hz:

as you can see the aeroport diameter is 6", but i couldn't find PVC in that size so i bought two 3" PVC pipes... how do i have to cut these to keep my 32hz tuning?

Looks like its a 6in port but pipe thickness is 1/4in 6 1/2 outer diameter you can use a thinner wall pipe if you can find one

i bought two 3" PVC pipes... with the 6" port it had to be 13" in depth to reach 32hz... do i have to cut both 3" PVC's to 13" to reach this same tuning? or should they be longer/shorter?

no... just no. 2 3" does not equal 1 6"

so then what should i do since i can't find any 6" PVC? it doesn't pass the same amount of air? because i had a few people telling me it did...

That box is way to big for a single 6" port.. Why not shoot for a single 8"?

2 4" ports is close to a single 6". Just go to parts express and order a 6" aero port kit or you local sewage supply store should have 6" drain pipe.

One 6" port at 13" long = like 28" of port on a 4.5 cuft box.. That's tiny.

Any particular reason you're shying away from port area?

Just go with the 'general rule' of port area.. 9-13 inches of port per cube if using an aero or 13-16 inches per cube for a slot.

Woah, woah, woah.. Just saw this. The 6" PVC can be found at lowes and costs roughly 12 bucks. It is 2ft long and located in the plumbing section in a different section than the normal white PVC. I think it is sch.45 but I don't remember for sure.
