Sub 18 DIY buildingplans?

[Torsjobe]

Hi! Newbie on this site!
Is there someone who have any buildingplans or CAD on the SUB18? Me and some friends are planning to build the M2 clones and the SUB18 to complement the M2;s. Any help is very welcome!
Best regards Toby

Not my speakers, but I have heard them and they are pretty impressive, I'm interested to see the plans too.

On Lansing Heritage, there is a thread on the Sub18:

However, I found this thread on AVS Forum to be more helpful on doing my own DIY version of the SUB18:

There they not only figure out the dimensions and volume but also discuss altering the size some to improve the response.
