Well sort of, everything he said is right except, "The port is to let sound waves in and out so the box or speakers dont rip themselves apart from the vibration.", hence a sealed box.

all you audio geeks out there and this guy has to wait 20 min for an answer from a mechanic. The port is to let sound waves in and out so the box or speakers dont rip themselves apart from the vibration. Also the port diameter and length are tuned to accent certain frequencies, mostly low, bass. the wave length of the sound you want to hear best will have a specific venturi diameter and length. I dont remember the formula but I learned this in Physics class.

The "Port" is to let air in and out of the box, not sound waves, the speaker is already on the outside of the box. It has to do with making a smaller speaker sound louder and thump harder, its combined with the use of stuffing in the box.

Yes, james is right. It allows the speaker to move easier. Also easier to mess up your speaker if you don't know what you are doing.
