Recommended subwoofers for example are any more budget type of subs such as any Sundown audio subwoofer up to the U series. DO NOT USE THIS BOX FOR ANY BIGGER SUB THAN THAT SUCH AS THE X SERIES, ZV5 SERIES AND UP. IT WILL BREAK THE BOX. Anything above that in size and you would want to purchase one of our custom one off (hand built to order) subwoofer boxes.

    Best pre/pro fab box

    Posted by Dylan Morton on Jun 08, 2022

    The box I had from my local audio shop was nice but normal pre fab boxes are always tuned to high. This D4S box is tuned perfectly super loud and nice and low! Super happy with the box.

    12 inch profab box

    Posted by ROBERT EDWARDS on Mar 07, 2022

    Well my box came with two pretty smashed in corners. I think it is a very well built box and would probably sound good but I think they need to step up the Styrofoam on the corners and on the long sides of the box because that is where I had two big old holes in the box. I think they should put Styrofoam around the whole box and double on the corners. Because not allowed to return it but they did give me partial refund.

    This box is absolutely flawless. the resonance is beautiful. the push terminals are legit. JP adds a personal touch to the packaging and the Team Down4Sound sticker is big and definitely will be proudly displayed on the van.
