When setting out to offer a line-up of premium, universal fit, subwoofer boxes, the end goal was to deliver a final product that was unlike anything else available on the market; setting new standards for quality and performance. The enclosure features a kerf style port, which means that the port construction utilizes the curves typically found only in custom, high-end, professional enclosures, allowing the box to offer deeper and more accurate bass. Furthermore, it’s precisely tuned to ensure that it delivers riveting low-end frequency response and the type of bass that turns heads from outside the vehicle.

The differentiating features that put this box in a league of its own don't stop there though; this 18-inch vented enclosure also utilizes high-end materials during construction, ensuring durability and reliability. On top of its outstanding craftsmanship, this box is also braced for extreme strength, and can handle even the most brutally powerful subwoofers. Internally, we line several walls of the enclosure with poly-fill to enhance the overall versatility and depth of sound that this enclosure reproduces with any given subwoofer. The premium push terminal wiring cup, that is built into the side of the enclosure, features 16-gauge speaker wire that is pre-soldered and connected to the terminals, making it easier than ever to wire up and install your subwoofer.
