does anyone know where to get a piece of sonotube in the uk? can't find it anywhere
AFAIK, Sonotube is basically PVC lined cardboard tubing, as used for casting circular columns and the like. As I recall, the last time I looked at some on a building site, it also had PVC on the outside, which would make it a bit of a pain to finish.
Give Essex Tube Windings a ring on 01375 851613, and they should be able to tell you who is your nearest stockist.
thanks mate. i will do that.
If you don't mind keep us informed as to how you get on. I'd be interested in playing with some if a viable option exists
Actually, I think i'm slightly wrong - inside is usually black PVC lined, and outside is shiny white cardboard (not PVC).
If you haven't found it already their website is here.
It looks like they're flexible on the finishes available.
i have contacted them and it is £65 plus postage. thanks for the help!
For what dimensions? How thick is the section?
50 inches in length 24 inches diameter and can't remember the thickness though
You can get a serious amount of veneered MDF box for that sort of money.
Is that the size you need ? If so, that's one Mother of a sub you're building - about 350 litres by my reckoning
So how do these tubes work?
In around 1987 someone told me you could get good base from a tube, so I bought six foot of 6" PVC sewage pipe, glued a really cheap 6" driver on it, connected it to the B speaker output of my hifi and was really rather unimpressed.
I was a bit naive back then.
Kind of crushed my DIY aspirations until RichH pointed me here a couple of weeks ago.
Sorry Dave, I apologise for getting into all this nonsense!
Sonotubes are basically the same as any other speaker enclosure - the tube shape makes them very rigid, and all that is needed is a top and bottom cap, so in theory they're easier to build (as long as you can cut circles!). The volume of the enclosure needs to be calculated just like it does for any other speaker. I think in the 'States, the tube stuff is a lot cheaper, hence their popularity. Do a google for "sonotube shiva" and see what I mean.
I spotted a some contractors laying some of those yellow gas pipes yesterday so I asked them if they had any spare sections and walked away with a 6ft section . This PVC pipe is about 2ft in diameter with 1 inch thick walls so should be a cheap alternative to Sonotubes and probably stronger. Its certainly heavy enough. The contractors said they get lots of requests from people using them for speakers! Has anyone else tried using this stuff?
Looks like no-one else has tried this, but sounds like a good idea to me. As with all these things, it's always worth a try, and I think you're onto a winner with this one - just need to decorate the living room bright yellow to match
I have done this in my car with a cheap sub and amp. Works but you need to make sure you mount the sub in the hole as airtight as poss. I siliconed mine in. Gave me the fuzzy bass i needed at the time... Used a Gas Tube off cut in snazzy yellow...
