It would be something like this:

Width= 24.00 inches
Height= 24.00 inches
Depth= 25.50 inches
Port Length= 36.73 inches
Driver Volume= 5.02 cu/ft
Slot Vent Width: 3.25 inches
Wood Thickness: 0.75 inches

That would be something like 5 cu/ft @ 30Hz with a slot port.

If you're going to be playing movies on this home setup, then 30hz is going to sound like ***.
