Help with simple design

[MikeyF 10+ year member]

Hey, I needed some help with a simple design. I was wondering if anyone could draw up a box design for a 12" DC LVL 4, tuned to 33hz. The website says it should be 1.5 cubes, but I defiantly thought they would be a bit bigger, like around 3. Would like it for a daily driver. But heres the info for the sub, and any help would be greatly appreciated. Thanks, Mike.
