Needing some help in a box design/dimensions

[alexj01_83 6]

I bought this speaker and put it in a prefab box. it does good but i think it could do better if it was in a better built box.( moves allot of air) it is in my room something the size of a dorm room. I use it mostly for music, I'm thinking maybe tuning it to 35-40 Hz. I would like to put it in a t line, but my box desinging skills are not up to par. Could some one help me out with some dimensions??? I'm not looking for sq. I know its a small speaker, but I'm in Iraq right now so I wanted something that Can pack up easily. and not take up to much space. Below is the speaker and the amp i have. Thanks for any help u can give me.
