For some people, the sealed enclosure for their subwoofer is just not their style. While that does provide very precise bass, it does not provide very deep bass, and that can play havoc with some music genres. For something like heavy metal, rock or even hip-hop, something like a ported subwoofer box is needed. This is because the ported subwoofer box creates very forceful bass.

How is it able to do this? Well, as the name of the enclosure says, it has a small vent that it uses to reinforce the low bass response. Because the bass is pushed through that small vent, you get much more output than you do in sealed boxes, and it is able to do this at any amplifier wattage. That means you don’t have to buy an amplifier for the subwoofer because it is using the principles of physics to do it for you.

This is a very popular type of subwoofer box in cars because it really gets things booming in the car. For the car stereo system that wants to rattle windows, the ported subwoofer box is what is key to doing that. As a result, you will not be disappointed when you listen to Led Zeppelin or any other hard rocking band with a ported subwoofer box.
However, there is one drawback to this design, and it comes in the form of space.

Ported boxes need to be much larger than sealed enclosures because they have to allow the sound to move in the box and out thse vent to create the deeper bass. This means it can be hard to fit them in cars except for a few select locations, like the backseat or the trunk. However, in the trunk you may lose some of the quality you were hoping for from the bass because it is so far behind you. In the backseat, you may not have anyone sitting there because of space restrictions or simply because the bass is too deep for someone sitting three inches away from it.

These are things you need to take into consideration before you go with a ported subwoofer box. However, once you do find the space for it, there are few other types of subwoofer boxes that are as good as this for getting that really deep bass that will rattle the windows of people around you as you cruise down the street with the bass cranked.
