Need help with BTL 12" enclosure

[Davidd92]

I've been working on an enclosure for my 12" Fi BTL. Except I cant seem to figure a box design out. If anyone could help come up with one that'd be great. some max dimensions are 32w x 15h x 20d. I would like it to be around 32hz and about 2.4cuft Any help would be outstanding!
