Im thinking of making a bass tube for my dual 8" subs for my next box.
I dont see alot of info on the net on good designs or what materials to use, so im wondering if the sonotube from Home Depot used to pour concrete pillars is strong enough?
If so does any reinforcemant need to be applied to the cardboard sheel or since its a cylinder already its damn strong?

loudsubz, I didn't read the google search JB provided, but I have made sonotube pods for 6.5's.
What I did was picked out two sonotubes that were close in dia. (I think they're nominally sized). Cut them crosswise so I had 4-5 tubes, then cut them all but one lengthwise. Used the solid tube as the outside then woodglued the cut ones inside it one at a time. Built up 4-5 layers. I then drilled holes and glued in those plastic plugs that you use in drywall to accept the speaker screws.
Overall it worked pretty well. But these were for 6.5's, not a sub.
Hope that makes sense. Good luck!

They wwere butted up against the door panels of my old '88 Camry that had no stock door speakers.
Custom cut them to fit and screwed them on from behind the panel.
It was ghetto, but it worked for me at the time.
I think an mdf cutout and some liquid nails would make a good end cap.

This should be of some help:

Endcaps can be affixed to the enclosure with standard wood glue and wood screws (I used flat-head screws, which went in and made their own coutersink). Be sure to put a bead of silicone caulk around the inside seam to seal air leaks.
