SK3X8V | Triple 8" Ported Universal Fit Subwoofer Box

  • Skar Audio introduces its SK series of line-up of high-performance subwoofer enclosures to bridge the gap between competition-grade quality and universal fit pre-fabricated enclosures.

    The SK3X8V is a triple 8-inch, universal fit, ported subwoofer enclosure. Featuring three independent subwoofer chambers, we engineered this enclosure to produce incredibly accurate and responsive low-end frequency response. In addition, each chamber features its own slot port alongside the bottom of the enclosure, which is tuned for the optimal compatibility and performance of most 8" drivers.

    Quick Facts
    Total Gross Air Space (Volume) 2.80 ft3
    Tuning Frequency 41 Hz
    Cut-Out Diameter 7.35"
    Mounting Depth 6.25"

    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. That being said, all of our enclosures are hand built using only the finest materials. On top of its outstanding craftsmanship, this enclosure 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. Each subwoofer chamber also features independent terminal cups, which come pre-soldered and wired internally with 16 gauge speaker leads that allow for an easy subwoofer installation. Finally, the enclosure is finished in a premium black trunk liner carpet and features an embroidered Skar Audio logo on the top surface.

Triple 8" Ported Universal Fit Subwoofer Box.

Thank you I received my package on time. Triple 8" Ported Universal Fit Subwoofer Box. I put 3 8" subs by Rock ville 2000 watch each subwoofer sound like A gang of midgets Rumbling wrestling in the back of my trunk . Listen You would have to hear for yourself so go buy some.
Also bought the Box From skar for 2 subs

I had my 8” subs in a .45 cu/in box and felt like they weren’t working well so I purchased this box and it put a huge smile in my ear. It is built sturdy inside and out including the external terminals.

Just bought this and got it wired to 1.33 ohms. Can’t wait to install it with my RP-1500
First bass system.

Overall a pretty decent box.

The box is great and works as it should. Only complaint is when I drilled the hole for the mounting screws, large parts of the box chipped off inside the box. Not a major issue, just an fyi.
