What kind of subwoofers does this fit?
This enclosure is precision-built for two (2) standard 10" round subwoofers. The cutout diameters are exactly 9.125" (9-1/8").

Will it fit in my vehicle?
Yes, it features a maximized internal airspace configuration while maintaining a heavy-duty 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 splits a generous 4.00 ft³ shared internal volume optimized with a high-velocity custom slot-port tuned to 32Hz. 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 10-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.
  •

Best pillow I’ve ever tried—hands down!
Size: Queen, Number of Items: 2
I’ve gone through a bunch of pillows over the years, but this BETU Cooling Pillow is by far the best one I’ve ever used. I sleep in literally every position—on my back, stomach, and sides—and this pillow works perfectly no matter how I’m laying. It really does have a cooling effect, which I love as a hot sleeper. Just make sure your room is cool too, and it makes a big difference. It came vacuum-packed, but it fully expanded within just a few hours. I was able to sleep on it the same day it arrived, and it was super comfy right from the start. I also washed and dried the pillowcase before using it, and it came out looking and feeling great—no shrinking or damage at all. Honestly, I look forward to going to bed every night now just because of this pillow. It’s supportive, comfortable, and totally worth it!

Excellent pillows!
Size: Queen, Number of Items: 2
This pack came with 2 pillows, one firm and one that was flatter and squishy. I absolutely love the flatter one! Most comfortable pillow I've ever used! The firm one was a bit too much for me, but my husband loves it.

It’s alright.
Size: Queen, Number of Items: 2
Not bad pillows. They are comfortable but mine came with an odd odor, kind of mildewy smell to it. Had to spray it down to tolerate sleeping on it.

Nice pillows
Size: Queen, Number of Items: 2
Have had these a few months and so far really like them! They don’t really feel very cooling, but I also run VERY HOT so it could just be me. The foam holds up well and hasn’t flattened like others I’ve tried. They come very compacted- I was shocked how much they expanded!
