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.

Oil them often
Beautiful boards. Wish the charcuterie side had more sections in the smaller boards. Be prepared to oil them often or the cut marks show quite a bit.

Just what I expected
Been using these for about a month now. I will say they do scratch very easily. My knives suck, and first use you can see every scratch. I don’t really mind because I feel like that’s expected with wooden cutting boards.
They look pretty, sit pretty, and haven’t split or warped on me yet. They have a good weight to them as well. I imagine you will have some upkeep such as using oil/board butter but I haven’t gotten to that point yet.

Very nice boards
Great cutting boards. Have handled alot of abuse. The fact that you get 3 sizes is a plus and may be the best part is the golder for them so they can sit on your kitchen counter amd enjoy their beauty when not using them. Do not put them in the dishwasher

No more plastic in my food
This is the real deal. Get yourself a cutting board maintenance kit and this will last 20 years. Great wood, no micro plastics in your food, easy to clean and maintain. And looks fantastic

Beautiful Acacia Boards That Actually Feel Premium and Thoughtfully Made
I’ve gone through a lot of wooden cutting boards over the years, and these immediately stood out as feeling much higher quality than most sets in this price range. The acacia wood has a really rich, attractive grain pattern and the boards arrived smooth, solid, and well finished with no rough spots, cracks, or cheap “composite wood” feel.
What initially caught my attention was the fact that these are marketed as non-toxic and free from mineral oil. Most people don’t think much about what wooden kitchen products are treated with, but I appreciated that these use a natural blend instead of petroleum-based mineral oil. The boards had a very clean, natural wood smell out of the box instead of that chemical/oily smell some cheaper boards have.
The three-size setup is honestly perfect for daily kitchen use. I find myself constantly rotating between them:
the large board for meal prep and meats
the medium board for vegetables
the small one for fruit, cheese, garlic, herbs, etc.
The engraved food icons are also a surprisingly nice touch because they help keep things organized and reduce cross contamination without looking tacky.
A few other things I really liked:
They’re lightweight enough to move around easily but still feel sturdy
- The wood is gentle on knives
- The groove catches juices well
- They look nice enough to double as serving boards
- Packaging was clean and plastic-free/minimal
Like any real wood cutting board, you absolutely need to:
- hand wash only
- dry them after use
- occasionally recondition the wood
If you expect dishwasher-safe convenience, these probably aren’t for you. But if you want attractive, natural wood boards that feel healthier and more intentional than cheap plastic boards, these are excellent.
Overall, these feel like a genuinely thoughtful kitchen product rather than generic mass-produced boards with a trendy “eco” label slapped on them. Very happy with them so far.
