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.
  •

Amazing durable product for your fur babies!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
We love this product! I have two aggressive chewers, one being a Staffordshire bull terrier, and the other great Dane mix puppy who is eight months old. They both love to chew and can be mischievous or anxiety ridden when they are bored and if they aren’t entertained with something. My Staffordshire bullterrier is a very aggressive chewer and we’ve had a hard time finding durable toys for her. This product is amazing. It keeps them entertained for at least an hour with the food that you can place inside. The molds are great and it’s really nice that I can make homemade dog treats to put in the toy. I use these toys every day, multiple times a day, and they’re holding up amazing. I love that the company includes the molds for the treats as well as a little key to open up the back of the toy to put the food in. This is a really good product. I have spent hundreds of dollars on toys and this one is worth the cost. I’ve tried bully box, Kong products, anything you can think of that says durability chewing, however this is really really good. I 100% recommend this product and I think it’s very fair pricing. Your fur babies will get a lot of playtime with this!!

Good puppy toy
Color: Brown, Pattern Name: Tree stump 1 Pack
Keeps the pup busy. He is not able to bite through it, it is very durable. Only gave 4 stars because it only takes him about 15 minutes to go through it and hes onto the next thing. Love that he is not able to destroy it though like other toys.
