MY STS build (Sono-tube-subwoofer)

[Mat-Moo]

Anyone made one yet? Very tempted to try it out and I've found a reasonable cheap source (I hope) for the tube (Details to be released!)

If you do I beg you not to post any details anywhere that I might see them

Sounds interesting...

Ditto.....

Toyed with the idea of using 450mm PVC drainage pipe - couldn't locate a short piece though, not that I looked very far... a sonotube design wouldn't fit in my movie room too well, but the idea of making one (or two !) appeals from the diy'er inside me.

Essex tubes want £35+vat for one column forming tube (delivered), although I'm unsure as to what length that is at present. Depending on the length needed and the chance to cut this up and share it, this maybe a cheaper option! However that is not the source I'm following at present. However what I need to do now is learn how to calculate the volume needed for the sonotube based on the "Rock" sub and tuning to about 20hz (I'd like anyway). I will probably mount the amp internally as well, aka (insert witty lost webpage here!) and hopefully end up with something like http://www.quux.net/roo/diy/sonosub/photos/P0001174.jpg I think I've already got an idea for the sock http://www.tinklersmotorcycles.co.uk.../stockings.jpg but again that's just an idea. Input welcome, especially any good websites you may of bookmarked! e.g. http://www.lungster.com/l/speakers/sonotubefaq.html BTW I want to mount the sub and port in the bottom aka http://www.lungster.com/l/speakers/sonosub/sonosub.html as then the top is kid safe but will have to look nice!

I built one about a year ago, the thread seems to have been archived I can repost pics if you want.

Volume's easy simply I think it's pi X diameter X length, I did the tuning using winisd and then adjusted it for my room.

I got the tube from Essex, but if you find a cheap supplier I may be interested in building another one.

Let me know if you want any more help

Any pics you have Always willing to take input and ideas! There would only be a limited supply, don't know how much yet. The £35+vat from essex tube is for 1m only!

Just found the original thread which has a few pics :-

Shiva tube sub complete

[Mat-Moo]

Thanks for that. I'm more likely to go for carpet or sock finish (in black). Just need to find some nice wood for the caps (mdf for internal bits).

[Mat-Moo]

Well believe it or not, I found what I needed on E-Bay! The seller says they have more http://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MEWA:IT and I've already been talking to them about the p&p which we are trying to sort out.

I was also thinking about using slices of treetrunks for the end carp finishers, but I don't know if it ould look correct or not. Beach would be nicer.

Also I don't have a sub/panel yet... maywell borrow the relax-12 stuff. Only thing is I can't decide on external, or internal mounting of the amp.

[slingshot]

That looks like a bargain, that's going to be one huge sub though !

I went for external amp since it was easy to make a box to house the amp rather than cutting a hole in the tube and putting batons in the sub, and much easier to change/upgrade the amp at a later stage. If you go external all you need to seal is a couple of small drill holes for the speaker terminals.

Be interesting to see how you mount it though if you for internal

[Mat-Moo]

Well I wanted the sub and port in the bottom, so I needed the wider tube. It maybe cut down a bit depending on how bg it looks when it gets here (and what swmbo says) but that's roughly a 300l pipe at the moment.

[Mat-Moo]

Internal mount, this is my fav style so far http://members.optushome.com.au/wcal...nstruction.htm

[theritz]

That's a neat piece of work, right enough. All it needs is a Sounds Very Serious ( ) badge on the front.....

Well I didn't think it would cost so much, but he reckons the tube ways 20kg and he sent it via TNT today so I should get it on monday at a cost of £20.... Oh well I guess it's still cheaper than Essex tubes! Better buy some mdf now and I think the internal mount amp is nice!

[IronGiant]

Any left over?
