Well after a lot of playing with WinISD and using a few bits of cardboard to see how much room this box could end up taking I've decided to go with the 12" XLS and a PR in a 60L box with 110grams added to the PR. It seems to model pretty closely to the vented solution and volume is down a bit which is good. I've resigned myself to the fact that this will not be my only subwoofer and so its become more of a build it and see how it goes and then at the very least I will have gained some actual expereince and have a fairer idea of what I'm actually looking for in the real world rather than dealing with figures.
Using 2 PR would be nice but cost starts to get in the way, at least this way I can in the future experiment with vented/more drivers/radiators if I want to. The huge ports kind of put me off, that and my ability to make huge flares. I modelled the 10" XLS with one PR which everyone seems to be fond of and it looks pretty much exactly like mine but with a bit less SPL so hopefully I'll be pretty happy with it.
If I'm doing something horribly wrong let me know!
I take it WinISD works out the inital mass of the PR via the Qms/Fs/Vas etc? Ie where you choose the "added mass" it is actually the added mass and not the net mass of the radiator?
Thanks for all your help though guys

It's not that hard to build flares:

Just use some body filler
Let us know how you go with it Kev
