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?

woo, thanks alot jeep

 

for those who have made them, did you use the threaded rod in the middle between both end caps?

 

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!

what did you do for the other end? did you put an MDF cap on it? or did you mount 6.5" on either end

 

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.

 

oh ok, its a little different the design im going after, Im making a whole sub container for them, not just a baffle for some door speakers

 

Yes I realize that but the fab of the tube might be helpful. I made a long enough piece to just cutoff chunks for the pods. 24-30"? Might be long enough for a bass tube.

 

This should be of some help:
