And yall thought I was kidding.

 

you can use a concrete round form from homedepot, cap the ends - and apply resign to the inside to give it more strength, - the new log!

 

crap thats heavy but definitely doesnt tranfser sound.

 

Those concrete forms are thick cardboard if I'm not mistaken. Probably wouldn't be too heavy, never tried it though.

 

ooh round "form" I missed that. I thought we had moved onto actually concrete. I dont think any thickness of cardboard could handle the pressures a sub produces could it?

 

go to home depot and get a 12 round piece of pvc tube and let imagination run wild it is a perfect circle

 

They are called Sonotubes, and they work great as enclsures. They are cardboard, but like 3/4 inch wall thickness.

Grade A...have you bought these at HD? I've been looking for a local source. I found a couple online places, but shipping was big.

seen them there or lowes!

 

that is why i said to coat with resin!

 

I'll have to do some looking...the guy at Lowe's by me just gave me a funny look...

These tubes are rigid enough for two reasons. First, they are thick. Second, they are round. For tubes, round is the most pressure resistant shape that there is. Think about it in PSI, and vectors. In a flat sided box, say 12x12x12, you have 144 sq inches, in any one direction, to apply pressure to. In a tube, you really don't have any sq inches in the same direction, since the sides aren't flat.
