you mean 52' ? because that's either a really large box or a really small person

thats a pretty big box you got there you must be goin with 18's....but with a port 32" wide (or long) and 12" high at 20" deep that will give you nearly 15sq" of port area/ per cube... at a 33hz tuning....and this box will be around 26cubes after port displacement...hope this helps

What thickness MDF are you going with? Are you going to double up all around, double up just the baffle...what's the displacement of your subs? How much space is your internal bracing taking up? What kind of setup are you looking at doing with that box?

If you use 1" MDF all around you'll have 28.6ft^3 to work with before any displacements, if doing 3/4" all around you have about 30ft^3, and a little under 29ft^3 with a double 3/4" baffle. Double 3/4" all around and you're down to 26.2ft^3 before displacement.
