In the car subwoofer industry, there are almost as many types of subwoofer enclosures as there are brands and sizes of subwoofers. The differences between these enclosures can have a great effect on the sound your subwoofer produces, so it is important that you match your enclosure to the sound you re looking for. In car audio applications, the near-infinite number of configurations tends to fall under a few main headings. In this article, we ll discuss a few of the major types of subwoofer enclosures that you may happen upon while looking to house those precious component subwoofers that you ve just purchased.

What Type of Car Subwoofer Enclosure Do You Need?

A sealed enclosure is an enclosure that, as you may have guessed, is completely sealed off. This is generally a particleboard box made to specific dimensions required by the subwoofer. It can be empty or stuffed with an insulating material. The insulating material can vary from standard fiberglass insulation to polyester foam. In any case, the objective of insulation is to increase the perceived volume of the subwoofer. This type of enclosure produces deep and accurate bass. This is the ideal subwoofer enclosure for those less concerned with power and more concerned with precision. If you want an enclosure that will help your subwoofer crank out hard-hitting bass, read on.

For a more powerful bass sound, consider a ported box. These subwoofer enclosures are cosmetically similar to a sealed enclosure, with the addition of a hole or vent. This port reinforces the low-end frequencies that a subwoofer produces by allowing sound produced by the rear of the speaker to reach the listener. These enclosures are also typically smaller than sealed enclosures. This type of enclosure will deliver large-volume, powerful bass, ideal for genres with heavy bass like rap and hip hop. If this simply isn t enough power for you, continue reading.

A bandpass enclosure is a very technical and rather complex enclosure designed for absolute maximum bass power. It s typically constructed in two chambers. One is a sealed enclosure that houses the driver and the other is a vented enclosure that resides in front of the speaker cone. This type of enclosure is devoted almost entirely to volume, so you will likely experience distortion and inaccurate bass, especially at high volumes. If you just want to rattle your car until all the loose parts fall off, this is the enclosure for you.

These three types comprise the majority of car subwoofer enclosures, though others do exist. Some car subwoofers can be mounted on their own on a flat particleboard panel and perform well. These are called  free-air subwoofers.  Others use folded horns to amplify sound in a box or on their own. In any situation, there are plenty of different subwoofer enclosure configurations to choose from. Make sure that the one you choose works with your driver, and enjoy your listening experience.
