What kind of subwoofer does this fit?
This enclosure is precision-built for a single standard 15" round subwoofer. The cutout diameter is exactly 14.125" (14-1/8").

Will it fit in my vehicle?
Yes, it features a maximized internal airspace configuration while maintaining a high-output deep cabinet profile suited for SUVs, trucks, large trunks, and cargo areas. The exact external dimensions are 33" W x 16.50" H x 21" 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 is precision-engineered with a massive 4.00 ft³ of internal volume and a high-velocity custom slot-port tuned to 32Hz to deliver incredibly deep, heavy-hitting, and highly efficient low-frequency extension tailored perfectly to high-performance round 15-inch subwoofers. It features an upgraded 2" round nickel-plated binding post 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.
  •

Size seems spot on shoe is beautiful
Size: 12, Color: White
These are beautiful shoes. A great cross between the ubiquitous flat as a board shoes like vans and tennis shoes. More comfortable than the super flat shoes and more formal than sneakers. Very soft leather. Not much arch support and I don't know if an insert would fit well. I am between an 11.5 and 12 in most brands (actual foot length from heel to tip of big toe is 11 and 1/8 inches). These fit perfectly in a 12 with room for comfort. An 11.5 probably would fit but snugly. I do not agree that they should be sized down at least based on my experience. If you can get these for under eighty dollars like I did they are well worth it. I'll be wearing them all summer.

Weightless, well made. But there are problems with size
Size: 8.5, Color: White
I bought it for a teenager, for size 81/2. This, according to the dimensions on the page, is 25.9 centimeters. They came, the size was indicated correctly, but they are large for the child. Very large. They fit me, size 10. The child is disappointed. Well made, look neat on the foot. Almost weightless But I can't give the maximum rating. I wish the seller to deal with the size grid.
