Box advise for Eclipse 88120dvc

I have this sub laying around, so i thought id put it to use. Should i go ported or sealed? If ported what size box and what tuning should i use?

I want this sub to get as loud as i can possibly get it...but still retain some sq, and get low, very low. I do know that this is an sq sub, so i dont plan on winning any comps with it, but i know it has potential to get decently loud. i have plenty of power on tap, so thats not an issue...just need some suggestions for the enclosure.

thanks
