For an OB (Open Baffle ) just a BIG bit of plywood that is bigger than your woofer will do, although that is just for starters.
15inch woofer so I'm thinking that a 1/2 sheet of ply cut in two bits may do.
Woops is ply in the US the same size as here? 1200mm * 2400mm, that's 4 by 8 feet, so a half sheet is 4 *4 so cut that's 24 inches by 48 inches, add short side wings about 3 or 4 inches deep.
Both side should be the same driver tho if using in stereo or your front L & R

Best plan is to put all subs in a single cornor
No spread em out, randomly spaced around the room sometimes works so much better.

My HT has 5 subs at the moment; 3 in front one in a rear corner and one in a front corner for a little bass boost

okay so heres what i ended up building... a sealed box that is 4 feet long and the internal dimensions on the end are 17 and a quarter by 17 and a quarter. do you think i could get away with putting the 2 speakers in this... it sounds really good with the one so far.

Thats around 8 cuft and you need at least 3 per so you should be ok. You really need to brace a box like that and try not to mount the drivers centered or have any equal dimensions. Where is the one mounted on the box? You could mount the other one directly behind it in a Push Push configuration and gain some SPL. Where in your room will this be located?

I'd mount the other one on the other end but you need to make an "X" brace that runs the length of the box and braces all four sides to each other. The brace should be made out of plywood with at least half of the wood removed or you can use pieces and strips. Here is a link to give you and idea of what I'm talkin' about. The brace needs to butt up to the back of the magnets so both drivers are coupled to each other thru the brace.
