Hello again all...
I have a pair of DVC Rat Shack subs, that, since I have them, I would like to build a simple cheap enclosure...but would require dimensions. I have the specs, and will post below.
My design goal is for a taller, maybe more narrow enclosure, with both drivers front-facing. (similar to the JL Fathom design.) I may or may not add a grille at a later date.
Here are the specs I have, not sure how accurate they are...

Thanks guys
