When referring to subwoofer enclosures, ported and vented are the same thing, as opposed to a sealed box. Sealed boxes are said to provide a harder "hit" and better sound quality but may not sound as loud as a ported box. Neither type of box is particularly "better" than the other, so the choice is between SQ (sound quality) of a sealed box vs. the louder but slightly poorer sound of a ported box. Hope this helps!
Yes it should be vented
To get the best quality out of a subwoofer is to check the RMS power rating on the sub and make sure that the amp is sending that power out in that power range. if not enough power is going to the sub it will not perform to its fullest but if too much power is going to the sub it will not sound good and possibly blow the sub. and also the type of box the sub is in effects how good it sounds. a sealed box will give you a longer range of sound while a ported or vented box will give you more bass.

Heating a sealed flask with a cork can cause pressure to build up inside and potentially lead to an explosion. As the contents of the flask heat up, they expand and create more pressure inside the sealed container, which the cork may not be able to withstand. It's safer to use a vented closure or open container when heating substances.

If the attic is well sealed from the inside of the house and well vented to the outside the air can be considered the same.
The best sounding sub enclosure typically depends on the type of sound you prefer and the specific subwoofer being used. Generally, sealed enclosures provide tight, accurate bass, making them ideal for music with a focus on clarity. On the other hand, vented (or ported) enclosures can produce deeper bass at higher volumes, which may be preferable for genres like hip-hop or electronic. Ultimately, the choice should align with your listening preferences and the characteristics of your audio system.
Yes, range hoods should be vented outside to effectively remove cooking odors, smoke, and grease from the kitchen.
a vented battery is vented and the regular battery is regular
when should crawl space be vented
In General, NO. The Roof and Attic Spces below it should be insulated from Heated spaces inside your home according to local building codes. The attic and roof spaces must also be vented properly with soffit and ridge or power vents s cold attic in the winter will keep ice and snow from melting under the courses of shingles. A well vented, cool attic in summer will dramatically lenghthen the lifespan of asphalt based roof coverings. The interior spaces of your house should be insulated and sealed/vented according to local building codes and by licensed professionals. For a roof, the colder the better, all year.
A vented gas cap vents the gas fumes into the atmosphere. A non-vented cap system routes the fumes thru the engine to be burned.
