sealed with give you nice tight, punchy bass, great for SQ. ported will be a bit boomier and louder with less SQ. it's more of a personal preference thing than anything else on what you want.

I personally like sealed better. I got the below from a basic car audio electronics site I look at when curious about something.

A sealed enclosure will be the smallest (for a given response shape) and will have good low frequency extension but may not have the best low frequency extension. If space is limited, this may be your best choice.

A ported enclosure will generally have a better low frequency extension for a given response shape (alignment) but would require a larger enclosure. If you made the enclosure as small as the sealed enclosure but ported it to gain the low frequency response, the output would deviate from the desired flat response.

A bandpass enclosure can sound good and give you a flat response but most of the generic bandpass enclosures are not designed for a flat response. They are designed to impress you in the stores. This means that they are built to produce a large peak at some frequency near 60hz. These enclosures will work well with something like rap music but generally won't sound good with other types of music. If you use a bandpass enclosure, it should be designed specifically for your speakers.

If you're building your first system, I'd recommend a sealed enclosure. It is the simplest enclosure and will be the easiest to get right. A sealed enclosure only needs to be the right size and well sealed. Alright... Enough of my opinions. Move on to the next section.

i was a big fan of sealed enclosures, until i got the ported box i have now. with the rite amount of power, the tightness is there. its as easy as this, if you want have "concert sound", get a sealed.. if you want your chest to shake, get a ported box
