    So yeah, someone on another forum has helped me to find some sonotube! 24", but I was wondering how much I would need to properly suit a Tempest...there's a 8' minimum buy, so I was hoping that it'd be at most 4'...

    Lastly, ANYBODY IN SOUTHEAST MICHIGAN WANT TO SPLIT AN 8' TUBE? Assuming that 4' is all I need, that is. [​IMG]

    Well, looking at PatSun's site, looks like all I need is 41" of a 24" diameter sonotube! I'll be making a design almost exactly like that...

    Now it's just a question of finding someone to split the tube with! [​IMG]

    Joe,

    Yeah, I finished my sub that's very similar to Pat's Sunosub II about a month ago. I used 43" of the 24" sonotube for an internal length of about 41" (take off whatever amount of end plug you'll have on each end).

    Regardless, you'll probably be OK to cut it in half and have 2 48" sections.

    If you can't find someone to take the other section, consider keeping it for a friend who has to have one after they experience yours. You could even help them build it since you'll be an expert by then!

    heh, yeah, but as a student, shelling out $45 extra for an uncertainty is...frightening. [​IMG]

    But you might also ask, what is a student doing with a sub like this...hehe. [​IMG]

    Where could I find construction details on Pat's Sunosub II?

    Once you decide on the alignment/Vb, it's a simple matter of looking up the formula for the volume of a cylinder in one of your books. (Hint: You already know "r".)

    Phil-E-Guy, Pat's page for his Sonotube II:

    http://www.io.com/~patman/sunosub2.html

    I'm looking at building one, too. I haven't figured out exactly where to get one "construction supply" and "cement suppliers" are vague to me - need something more concrete. (concrete - Sonotube- oh I made a funny!)

    Check the Yellow pages for local sources (Construction Supply companies).

    I recommend you figure out the volume of the enclosure and size of the port you want and then check out this site: http://www.quux.net/roo/diy/sonosub/sonocalc.html

    The driver volume for the Tempest is 305 cubic inches. Put in the rest of the variables you're interested in and you'll be good to go. You'll be able to quickly see the differences in going to different diameter tubes if you like. I found it very handy.
