Looking for larg round tubing

[turtles1118 1]

looking around for some round tubing to fit an 18 inch sub, i had seen someone who has done this befor on the Mach 5 Audio test bed site but I cant find that site any more.

If any one has done any thing like this befor tips and how to measure air space would be a big help.

Thanks.

Pi*r*r*L is the volume calc for a cylinder. (area of a circle times height)

Sonotubes are probably the easiest thing to find.

I got some...

Your typical 18 has like a 17 inch cut out...find out what it is...

Mine are like 17.5...which is perfect cause you gotta build rings for them anyway...

I got about 4 or 6 or something...

I'll sell them cheap but shipping will bite you in the butt...they are big and ups hates that LOL...

Where are you?

PM me if you don't want to say....if you lucky you close by and can come get one.

I am in Memphis TN.

Sonotube FTW! Check into your local concrete supply store for the best deals.

I'd definately say sono tube and maybe a couple layers of fiberglass to help sturdy it up. Its easy to make and cheap too. I just finished a sono tube for my oem tc10. It turned out real nice. I'm not completely done with my install yet, but I going to post a couple pics what I have so far in a different thread.
