Universal Subwoofer Enclosures are designed to fit in most trunks, hatchback spaces, and the rear area of most SUV's and Vans.

A sealed subwoofer box will deliver a tight, clean and accurate bass response and have a flat frequency response curve.
Ported Subwoofer Boxes» Ported Subwoofer Boxes
Ported or Vented Subwoofer Boxes have holes cut into each subwoofer compartment that allows air to escape. These vents/ports cause your subs to produce a loose low bass response that can be described as more of a low rumble than a quick "thud". Ported/Vented sub boxes are popular among people who listen to of rap, hip-hop, or any other bass heavy musical style.
Band Pass Subwoofer Boxes» Band Pass Subwoofer Boxes
Band Pass Enclosures are somewhat of a hybrid between a sealed enclosure and a ported enclosure. They tend to produce tighter bass than you'd expect from a ported box, but more rumble than you'd expect to get from a sealed sub box or enclosure.
