Well- you can't fit anything larger in the WO without making the entire box bigger via scaling or some other way.

And as soon as you have to change the design you venture into no-man's land.  You would basically have to re-design the entire box so its works.  I don't know what else to say I guess except that you can do it- we just don't know how it will perform.

Main reason you haven't seen it is it doesn't fit in many vehicles. The design is a lot more used for cars and by scaling up to a 15" sub, you are talking a pretty big box. Since you have the van, I would say go for it and see how you like it.
MrEZ, I know you have lots of time and MDF so why not?!
Kick it and let us know how it sounds.

Disclaimer,
The WO is built on a measured angle and reaction via using the single reflex fourth order bandpass enclosure model so scaling offers a number of options when stepping up to an 18. I am one of only a handful of people I know who have ever built bandpass boxes for subs that size.
Good luck

My thoughts on an 18" WO
I like scaling this thing so the basic premise is the difference in a 10" Sd and an 18" Sd. After that the numbers are generic since the design is not specific to a certain driver to begin with. I would go with 48"W x 46"L x 20" tall and here are the differences in the design. After this, you would just need to substitute some numbers into the plans for the original and start cutting. I have done this with the 12" version and was very pleased with the really deep output it had. COuld be interesting at very least to see some whoppin 18s in one of these.

hey mugsie,

dont you thik the 1.25 throat should be kept 1.25 instead of increasi  to 3" doesnt the sixe of the opening controll the bandpass? with the aditional height i imaging port noise wont be a problem? but you have buil way more boxes than me so i take your knowledge very seriously. i would like to one day build a big wo (18s would be fun) and scaleing it  RIGHT is something i have not seen DEFINITIVELY yet   ???

my best guess is to scale the whole box by the difference in driver cone area / size %
?

^ i guess that would make the throat 3" + or - for 18s  :-/

Actually, now that I do the math, I think it would be between 2.5 and 2.75" but yes the cone area increase is how I made the port size equivalent.
I did the same with the 12" (1.75") and the 15" (2.25") and it sounded pretty great.
I hope this works lol. I can't wait to find out if it pounds!
