I need a 8" port at 30" long. It will have to include a 90 degree bend in the box.
I'm having trouble finding any PVC to use or any pre-built tubes at 8". Can anyone point me in the right direction?

I got my 6" PVC from a commercial plumbing company... they had larger sizes as well.

Sonotube comes in 8" sizes... Lowe's should have it, depending on where you live... it is called Quik-Tube and is made by Quikrete.

It comes in 8" x 48"...



You could probably order it online and have it delivered to your local Lowe's if not available in store... or your local hardware store may have it or can order it.

Finding an elbow to work with 8 inch Sonotube would be a challenge. Other options would be 8 inch PVC pipe with an elbow which would probably be expensive. You could also try to redesign your box so a straight length of sonotube will work, or consider a slot port with the same surface area.

I wound up using 3 4" ports using pvc with 90 degree bends. The angle idea is a good one. I didn't thing of that.

I'm thinking of starting a new thread with pics of the build if anyone would be interested and if that's acceptable. Come to think of it I should start a small blog so anyone interested (and a few friends) could follow and see how the build is coming.

Please do! We are always looking for a new build thread that can be added to the "Subwoofer Database". :T
Mike,

Is there any preferred format for such a thread? For example, do most people like to have all pictures shown inside the thread? Or if the builder has their own web page with pictures and documentation, is just a link to that ok? And I don't mean a generic thing like ImageShack or similar with one line titles to each picture. I mean a real web page made from scratch. :) Or a combination of the two?
