Help me choose a box design

[pervitizm 0]

After seeking help from numerious forums..(ROE, Termpro, SSA, and SMD) I've narrowed down my box design to just two for my DC LvL4 18. I just do know which one I want to build. Should I go with box 1 or box 2

Box 1: Tuning is now looking right at around 33Hz.

Box 2: Tunning is around 30Hz

I would go with a single port for ease in building the box.
