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 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 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.
  •

Excellent for my sensitive skin and rosacea
Another excellent product from this brand. I have type 1 rosacea on my cheeks, even when I avoid triggers (like red wine, warm weather, etc.), and very sensitive skin overall. I've been using the cicalfate serum from this brand for the sensitivity, but it didn't help the redness. After two weeks of using this twice daily, I noticed a significant difference. After a month, I had no redness unless I encountered a trigger. Even then, the intensity of the redness seemed less. I tried going without this product for a month when the first bottle ran out, and sadly, the redness started coming back within a cycle of weeks. I've got this on auto-delivery now, along with the cicalfate serum. I never want to be without it!

Best moisturizer for sensitive skin
I have very sensitive skin and have tried many products over the years. This is by far the best daily moisturizer. I don’t wear makeup other than under eye concealer. This keeps my skin looking and feeling great. Not greasy. One bottle lasts about a month. I have probably bought this 10 times in the past year.

Not as good as the antirougeurs cream
I used to use the Antirougeurs cream and loved it but since they no longer make it, I had to switch. I have been using the redness expert cream for a week and it makes my face even redder. I also started to break out. The texture is good but I don’t think it works like the other cream.

Really helps with the redness
Years ago, my dermatologist recommended this line whenever I had a problem with redness. The redness occurs when I spend time outside, even with sunscreen & a hat. When I perspire it irritates my skin & poof, redness. I started using this, once I found it on Amazon, & this really helps to relieve the pain, discomfort & burning sensation. It has a cooling affect on your skin. Until I found this brand I simply suffered until the irritated skin healed. I apply this at night, especially after being outside & sweating & the redness is gone in the morning. I plan to use this until I no longer need it.
