tower speaker tube

Thinking about making some NVS like tower speakers, and was wondering if anyone has come up with a good way to make a large diameter tube. Were talking 8" or 10" diameter. It looks as if PVC is not close enough in standard size to use and the only other pipe I have found is some clear acrylic piping that is mucho dinero.

any help would be greatly appreciated.

Thanks!

That's fairly large... I've heard of friends using special hard cardboard tubes in car applications to make their own bass tubes, but I wouldn't do that on a boat unless I was wrapping the whole thing in fiberglass afterwards. I personally did some 6.5" acryllic enclosures, and yeah - for two, it cost me like $80. If I were doing a tower, I'd probably just get back into fiberglass... Of course, I'm sure you could find a large enough PVC and Cap to cut the correct size opening into the cap - but it's hard to say who'd carry that.

buckets

Yeah I thought about buckets. You would have to take them and then fiberglass the inside of them to add strength, and then paint them.

at that point, I think I would find the cardboard tubes... I'm thinking something like concrete molds, or something like that? Then again, if you got the glass out anyways, why not carve up your own design and glass around it for one nice big molded structure?

you could take sheet aluminum and roll it, weld the seems, weld in a piece of aluminum plate on each side and cut out a hole on one side to mount the speaker in. It's pretty straight forward. I think this is the way a lot of companies make thiers.

Ace...that is exactly what I have talked to my sheetmetal fab shop that makes stuff for us at work. The only problem is that that is alot of welding (seam, and both ends). Doing that though, I could have pem hardware pressed into the flange for the speaker. I am waiting on a quote from him for a couple of sets. He said it would be simple for him to put it on his roller and roll up a perfect circle.

I made mine by cutting out an internal skeleton of plywood, then wrapping it with a thin metal to give it some strength. From there I wrapped it in a fiberglass wrap, sanded, painted, sealed and they work perfect.
