    Quick Facts
    Internal Air Space (Volume) 4.75 ft3
    Tuning Frequency 29 Hz
    Cut-Out Diameter 16.625"
    Mounting Depth 13.50"

    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.

Awesome sub!

Best sub I’ve owned hands down. I would recommend this to anyone and everyone

Corner damaged, but solid

Arrived with a pretty dinged corner, but I had planned on modifying it anyhow. Rock solid box that specs out about like described. And unlike another review here, it came with 10ga leads soldered to the terminal cup, although I went bigger on my setup. Added a couple braces inside and some cld, and added a 3/4" baffle to double up the front and dropped an fi audio q18 in it for a temp setup on 2400 watts. Gotta say I'm surprisingly impressed with this box for a prefab. Little small for a solid 18, but still has incredible output, clean sound, no flex, and plays really nice and low. Carpet is really nice, but the contact cement holding it in certain areas is a little lacking. All in all, for $110 on black friday, this is an awesome enclosure if u want a quick decent solution to custom building!

Box came corner dented

I took a offer once received not checked ports so may need to be safe ad some liquid nails as when I build them use that and brass screws on US MDF, but the design cleaner and looks professional accept where hang my dogs toy over dented corner but box heavy 3/4 guess Chinese MDF other hand US be more heavy, but for what you pay and get it is what it is and at that worth it, clean. Ports and bracing not sure why not more poly in box where port not affected bare wood just might make it maybe helps already to fool sub if needed more space. I tried Fi 18 and SKAR EVL 18 - the box worked. Just wish they had VXF 18", one above it, not for me. SKAR was easy to work with on issues, concerns and or problems.

Fits great in 99 CRV

Who needs trunk space? Fits perfect in my 99 Honda CRV. Im probably going to mount handles and feet on this enclosure so I can throw it in my living room home theater for when it isnt used in my car. This enclosure is WELL built. Hefty. and fits perfect in my application. So happy I went with Skar. I will be using Skar for all my upcoming builds.

Thanks SKAR for putting out great products at great prices!
