i just bought a 15" speaker cone for dirt off some guy, (my mate pre-bagsed an 18" one) anyone had any experience building cabs? any tips on maximum bass efficiency? I have no idea what i'm doing but i'd love to do it well.

I'm in the middle of building a cab for a 12" sub. If you want to do it right it takes a bit of research. If you have the technical specs, life is a hell of a lot easier for you - measuring them is a real pain. Check this site for basic info http://www.diysubwoofers.org/

Also check this software that calculates the size of the box for you http://www.ajdesigner.com/speaker/index.php - I found it quite helpful.

I haven't tried these guys out yet, but they sell all manner of speaker building stuff - useful for getting stuffing material and flanged ports (if you need them)http://www.wilmslow-audio.co.uk/

Edit - there is a trade off between speaker efficiency and frequency response -there is no right or wrong way as far as this is concerned - depends on what you want.

nice one, really aprecciate this, maybe when we're all done some pics up on here?

some general speaker info here, maybe of use.
stuff about cabinets at bottom of page.
not exactly comprehensive but includes some valuable maths.
page on crossovers is worth a look, also.
