All of the sonotube subs I've seen/read on DIY pages are downfiring. Are there any drawbacks of putting the tube on its side, making a front firing sub?

None other than the fact that the tube itself isn't very strong, so it's easy to dent.

I read in Make Magazine a while back about Minwax Wood Hardner. IRRC, They said it was excellent for use on cardboard prototypes and such. It gave them a hard outer shell. Has anyone tried this with a sonotube? I know I've seen people discuss using it with MDF, but not cardboard.
Just a thought if durability is a concern.Comment

The safest thing is to frame it with a ply facade or glue carpet on it.

That's what I had in mind, Thomas. Put the tube on its side, make a rectangular frame with endcaps for ends and bottom and a 1/8" ply bent around the top curve. From the front, it'd be shaped like a half circle sitting on top of a square. The main benefit for me would be not having a couple of 250lb boxes to worry about when I'm moving!Comment

Hey MC99,
The last sub I built used 24" sonotube and I covered all sides in 1/2" Birch ply added feet and all to the ply. Driver and ports are front firing. looks like a regular box but it is very large; over 25" square.(EDIT: cubed) It is, however, much lighter than a regular box this size though."The most successful people in this world have also failed the most"Comment

I am pondering the same idea, although I am thinking of boxing the tube completely.Originally posted by madclown99
One problem as I see it, is that the overall weight of the tube inside 1/8 ply frame is quite light. The good thing, - you can easily lift it and move it around. The bad thing, - it will definitely ‘walk’ around the room, particularly if the driver used is like what I have here, - the Avalanche 15.
I am considering putting 2 drivers at the opposite ends of the tube/box to take advantage of force cancellation. This way the sub should remain where it is intended to stay. I suppose one can also anchor it, but it creates other problems.Comment
