15" Ported Subwoofer Boxes

If you like your music “boomy”, vibrating your car’s body panels, you want to consider a ported (vented) enclosure. These types of enclosures, when built with the properly calculated volume and tuned to the correct frequency for the subwoofer, are generally louder than a sealed enclosure. In a vented enclosure the woofer and port work together with the port resonating like a pipe organ.  This works with the woofer to generate more bass than a sealed box.
