Ported

Advantages:
More output at the tuning frequency as compared to the same woofer in a sealed enclosure, higher efficiency.

Disadvantage:
Larger enclosure size, Calculating enclosure and port dimensions more difficult,easy to blow woofer if power handling limit is exceeded.
The box itself acts as an amplifier, yielding to more bass than a sealed enclosure (3 to 4 dB). Ported boxes do not have a linear frequency response. If the box is not built according to specifications, it will not sound good. The box design acts as a filter, cutting off lower frequencies.

Bandpass

Advantages:
Bandpass can be designed to play loud or low depending on your needs, by design produce a limited band with, the woofer cone does not move as much other designs reducing the chance of added distortion.

Disadvantage:
Bandpass boxes have a tendency to sound boomy not tight, typically these enclosures don't sound as good reproducing Music requiring great detail such as Jazz or Classical music.

Overall
These enclosures are usually big, and very unforgiving when precise volumes and port sizes are not followed. Bandpass boxes also tend to mask distortion. If you can't hear distortion and turn your stereo down in time, you could damage your subs.
