Sealed Subwoofer Boxes Information

Sealed Subwoofer Enclosure Information:

A sealed subwoofer enclosure does not allow any air to enter or escape the box. A sealed subwoofer box allows your subwoofer to perform with optimal transient response for tighter bass and enhanced sound accuracy. You can choose from single, dual, and triple slot subwoofer enclosures to house your subs. Our boxes come standard with a circular hole, but we also carry square enclosures for Kicker subs. Shallow mount subwoofer enclosures are designed with less depth to match shallow mount subwoofers, a great option if you have minimal space behind your seat or in your trunk. The same can be said of our hatchbox sealed enclosures, which are angled to save space in your cab. Most of our sealed boxes are designed with dense fiberboard and a thick layer of carpeting for enhanced durability. For the ultimate enclosure, check out the fiberglass sealed subwoofer enclosures, which include a lifetime warranty.
