April 8, 200916 yr You only have 2.6 ft^3 gross volume using 1/2" MDF. The absolute least size port I would do (and it is small) is 14" x 2". That will be 30" long for 33 Hz and will take up .6 ft^3.Factor in driver displacement, and you are just under 1 ft^3 tuned to 33 Hz with 14 sqin of port area per driver .
