port area is too small!!! I would run on the high side like 16 sq in per cube...I run mine @ 20 in per cube and it is a very noticeable diff in out put I even dare say 2-3 db

that box will only have 43.5 in sq of port area you will need a MIN of 48 but more like mid 50s to mid 60s

just off top of my head if you go 16 x 35x15 that will give you 4.8 and change cubes but after sub disp. and port it will put you round 3.8 ish cubes.....dont quote my in using my fingers and toes here.....
