  • Our take on the CT1X8 Single 8” Kerf Ported Universal Car Subwoofer Box

    The CT Sounds CT1X8 is an empty single 8-inch ported enclosure built for deeper, louder bass than a sealed box of the same size. Its kerf-style port, dado and miter joinery, recessed side panels and poly-filled lining are features usually found on custom builds, not off-the-shelf universal boxes. The 7.37-inch cutout and universal fit let it take most 8-inch subwoofers, and the pre-soldered 12-gauge wiring with an 8-gauge terminal cup makes hookup plug-and-play. It suits shoppers who already own an 8-inch sub and want more low-end without paying for a custom enclosure.

    What reviewers say

    Owners of the CT1X8 tend to praise its build quality and the output gain over sealed boxes, calling the kerf port a step up for the money. Some note that it is bulky and that results depend heavily on which subwoofer you install.

    About the CT1X8 Single 8” Kerf Ported Universal Car Subwoofer Box

    The CT Sounds CT1X8 is an empty single 8-inch subwoofer enclosure with a kerf-style port. The port is a design usually found in custom enclosures. The box is pre-fabricated and universal, and its 7.37" cutout diameter fits a wide range of 8-inch subwoofers.

    The box is made from 3/4" MDF. Dado joints connect the left and right pieces to the back, top and bottom pieces. Miter joints cut at 45 degrees join the corners. Recessed side panels add to the air-tight, vibration-free construction, and the internal walls are lined with poly-fill.

    The enclosure is wrapped in black carpet and has a flush-mounted black terminal cup. The cup has 8-gauge push terminals with red and black stickers marking positive and negative. Inside, 12-gauge speaker wires are pre-soldered to the terminal cup.
