Team D4S PROFAB Dual 12" PORTED Subwoofer Enclosure

Our goal with the Down4sound Prefab enclosures are to offer an amazing, low tuned enclosure at an affordable price. When searching the internet at all the cheap options available it was pretty disheartening to see people wasting their hard earned money on such garbage enclosures. Most of which are built of very flimsy material, tuned very high and either not covered or covered with some type of cheap fabric (because this makes them cheaper to build). I decided to offer a STRONG & LOW TUNED enclosure that all the true bassheads would love. That deep rich bass that is found in the lower 30hz range. 


  • 4.0 Cube Dual 12" Enclosure
  • Subwoofer cutout - 11 1/16"
  • .75" MDF
  • 31Hz Tuning
  • Mounting Depth- 15"
  • Black Bedliner Finish
  • Plastic terminal Cup
  • Plastic Bag
  • Foam Corners
  • Double Wall Shipping Box 
  • Good for up to 3000w Rated Power (Any higher power than this and we highly recommend you get one of our custom hand built heavy duty enclosures)
  • Designed by Bassahaulic Productions 


L x W x H: 32.5 x 20 x 16

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.

    Exceeded my expectations. Can’t beat it for the price.

    Sounds great. Definitely plays lower than I expected and takes every bit of 3000w with ease.

    Good “prefab”

    Well built box with good tuning, exactly what I was looking for saved me from building a box. only issue I had with it is the Mounting holes for the woofers, the bolt pattern was not correct the circumference was to small for my deaf bonce apocalypse woofers tried everything to make them work but had to make my own holes. Thanks for the awesome looking box D4S!!!

    This box would be better with 2 terminal cups, so if you are running 2 2 ohm subs, you can. wire them to 1 ohm.

    Sweet enclosure

    This box sounds amazing! I've got two Sundown SA Classic 12s in mine and this is a night and day difference from the cheap prefab box I used previously. Plus I got it delivered to my door in 3 days. Thank you for making a quality enclosure at a decent price!

    Best pre/pro fab box

    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.
