While the size of the sub is important, the type of enclosure you choose may have an even bigger impact. The enclosure, which is usually referred to as a box, is just that: a box that contains the subwoofer. The three main types of enclosures are:
- band pass
If you want bass that is exceptionally deep, then you should go for a sealed enclosure. In some cases, a smaller sub in a good, sealed enclosure will produce deeper bass than a larger sub in an open enclosure. This type of enclosure is great for tight, accurate bass that won’t necessarily shake your fillings loose.
Ported and band pass enclosures typically provide bass that isn’t as deep. In turn, they also provide louder sound. If you listen to music that demands extremely loud bass, and you don’t care all that much about accuracy, then you’ll want to look at one of these enclosures.
The other option is to select a subwoofer that is specifically designed to work without an enclosure. These subs are typically mounted to a board that is installed inside a trunk. The trunk itself has to be relatively airtight because it acts as the enclosure.
