What kind of subwoofers does this fit?
This enclosure is precision-built for two (2) standard 12" round subwoofers. The cutout diameters are exactly 11.125" (11-1/8").

Will it fit in my vehicle?
Yes, it features a wide, deep-footprint shared airspace layout optimized to maximize rear cargo areas in larger SUVs, trucks, and trunks. The exact external dimensions are 38" W x 14" H x 26" D.

How is the performance and wiring?
Designed as a true high-end, custom-ported specification, this cabinet steps far out of the lane of generic boxes. It splits a generous 5.00 ft³ shared internal volume optimized with a high-velocity custom slot-port tuned to 34Hz. By matching proper volumetric requirements and optimized port dimensions, it delivers incredibly deep, aggressive, and highly efficient low-frequency extension tailored perfectly to high-performance round 12-inch subwoofers. It features upgraded 2" round nickel-plated binding posts for secure and reliable wiring connections.

   

PreFab™ Custom-Spec Series: The Off-The-Shelf Custom Enclosure

   

In the car audio community, off-the-shelf boxes usually mean thin panels, generic tuning, and choked output. We developed the LAB PreFab™ Custom-Spec series to completely rewrite that narrative. Proudly manufactured in the USA, this series delivers true custom-shop acoustic performance without the custom-shop price tag or wait times.

   

Each cabinet is precision-cut from solid high-grade MDF and engineered around a highly optimized, high-velocity custom slot-port design. Instead of generic calculation curves, these enclosures are built around real-world manufacturer specifications to ensure proper port area, maximum flow, and ideal airspace matching. It is the ultimate plug-and-play solution for audiophiles and daily bassheads who refuse to compromise on custom-level low-end extension.

        

The Custom-Spec Advantage:

   
           
  • True Custom Slot-Porting: Engineered with optimized port areas and precise tuning to replicate custom-shop low-end extension and power handling.
  •        
  • American Made Solid Build: Designed, cut, and assembled in the USA using high-grade CNC-cut MDF to ensure maximum acoustic efficiency.
  •        
  • Manufacturer-Spec Airspace: Built closer to specialized manufacturer parameters than any generic box on the market—ready to ship, ready to slam.

Thinner fabric than usual.
Size: Large, Color: Black Heather Full Zip
Good quality, but much thinner fabric than my other hoodie sweatshirts. Because of this, I have not been wearing it, but instead I've been wearing the thicker ones I already owned. This item was a good price; now I see why. It's too light for winter, and too heavy for summer. Not sure when it will be useful.

Good value
Size: 10.5, Color: Black/Black
They fit and they stay on my feet (I was worried because these are slip-ons).

Comfortable lightweight sneakers for casual everyday wear
Size: 9.5, Color: Navy
These sneakers feel like a decent value for the price. They are very lightweight, which makes them comfortable and easy to wear throughout the day, though that also means they feel a bit less substantial than more supportive athletic shoes. I have mainly been using them with business casual office outfits, and they work perfectly well for that kind of light-duty everyday wear. I would not personally use them for anything especially active since they do not offer a ton of support, but for casual use they have been great. I also like how easy they are to slip on and off. I typically wear a size 9.5, and these fit true to size for me.
