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.

1" fittings and decent quality
Size: 16'' x 7.87''
Difficult to tell from any description but these are 1" pipes and fittings. You can find this out if you look at product pictures and can see the 1 printed on a fitting or two that is it. I was trying to match existing pipes that were 3/4 inch so disappointed when they arrived. these are decorative as well. Not the same quality as actual black iron pipe you get at any home improvement store. Good enough for shelving and legs on furniture but I definitely would not stand on these or make a chair or stool that is meant to hold someone's weight. Fit and finish about what you would expect cheap and the flanges are threaded crooked like others have stated. Also when they state the sizes and lengths they do not take into account the fittings so everything will be longer slightly.

Good price for what I needed
Size: 16'' x 43''
Perfect for the coffee table I was working on, adjust to the size I needed as I only used 2 middle pipes for a 36” table top. Good durable pipes. The down come slightly scratched up as they weren’t packaged in anything protective so I ended up spraying them with a matte black.
