Logic systems cs1260sb dual 18" cab

I have x3 sheets of Baltic ply I'm wanting to construct the twin 18" push pull cabs need help with cutting plan and the baffle placement and if I should construct the baffle with marine MDF please any information would be most welcome as I have to have them ready before new year 

No real reason to use marine MDF, unless you're otherwise short on Baltic birch.

I think deriving the cut sheet for the cs1260sb isn't exactly a fun process. Unless you really need the small frontal footprint, you can also build the  www.eighteensound.it/media/W1siZiIsIjIwM...ZXYwNjAzMTUucGRmIl1d (reverse mount one of the drivers) or forget about push-pull and build the  www.speakerplans.com/index.php?id=gsub .
