You are talking about external ports, correct? Having the ports on the outside of the box is a good thing //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

pressure should be different outside of the enclosure compared to inside the enclosure so this could be a factor if the port isn't secured inside the enclosure. For instance if the pressure inside the box is really high and the port is long and only held by 4 screws, it could "ring" or vibrate. I don't know if this affects anything, but its possible. outside the box the pressure around the port would not be has strong so this should not be a problem. I always wondered this when I made boxes with aeroports, but the boxes sounded good so I didn't give it too much thought.

The ports do vibrate up and down some externally, but nothing crazy.

Basic airflow. With external ports the air doesn't need to circulate around them inside the box. Make for an easier in/out flow. External ports also helps with loading against panels & corners inside a vehicle without having the box really close to those panels blocking air flow.
