OEM-Spec™ Enclosures: Purpose-Built for JL Audio®

   

Dropping a premium JL Audio® subwoofer into a cheap leaky box is a quick way to leave performance on the table. Our LAB OEM-Spec™ enclosures aren't trying to reinvent the wheel. Instead, they are precision-built tools manufactured right here in the USA to do exactly what JL Audio® intended.

   

We construct these with rock-solid 3/4” CNC-cut MDF and feature 1” or thicker front baffles on select models to support heavier motors. These enclosures follow JL Audio’s exact volumetric blueprints to the letter. By utilizing their highly efficient smaller-airspace designs, you get two very practical benefits. You get increased mechanical power handling to keep your sub safe from over-excursion, and you gain a significantly smaller footprint in your trunk.

   

Available in both ported and sealed configurations for most JL Audio® drivers, the OEM-Spec™ line delivers the accurate, hard-hitting bass JL is famous for at a price point that actually makes sense.

        

Why It Hits the Mark:

   
           
  • Factory-Tuned Precision: Built exclusively to JL Audio® factory specs for optimal Thiele/Small (T/S) parameter matching.
  •        
  • Heavy-Duty Construction: 100% 3/4” CNC-cut MDF with ultra-thick front baffles on select models for maximum structural integrity.
  •        
  • American Made: Designed, cut, and assembled in the USA for strict quality control.

Good size
This works for most of the items (powder like cinnamon or beet root, etc.0 i need it for. I would like to have one that is 50 oz. It is airtight and a great product but I'm not convinced pumping it 20-30 times really helps.

Good product/unsure of air seal
We love this to hold our coffee beans, but we aren’t sure if it truly seals air out. It seems to work great though and our beans taste fresh!

Does not hold a vacuum
It does not hold a vacuum. I am able to pump and cause a vacuum where I cannot take the top off without pushing the relief button but give it a few hours and the vacuum is gone. Coffee is stale in a few days and I have gained nothing but the expense.

Does not hold a seal very long
Looks good. Quality materials and construction. Vacuum seal doesn’t seem to last very long. After a day the lid can be easily opened, regardless of how many times you pump it beforehand. More aesthetic than functional.
